Please, only buy or use sofas and upholstered chairs that do NOT contain any flame retardant chemicals. Be sure to look at the tags attached to the furniture that are required by a California law since 2015 (called Technical Bulletin 117-2013) to be on each new sofa and upholstered furniture. It will tell you if it contains flame retardant chemicals or not.

This is especially important if at some point you are thinking of having a child, if you are pregnant, or if you have children. The problem is that the flame retardant chemicals, which were added for decades to the foam in upholstered furniture, migrate out and so get into us (through the skin, inhaling, or by swallowing). Unfortunately, almost all of us have flame retardants in our bodies.  Where they can cause health problems.

Two new studies were published recently showing harms from exposures to flame retardants. The first found an association between flame retardant chemicals before birth (when the pregnant woman is exposed, it gets to the developing baby) and later reading problems.

The second study found that exposures to pesticides and flame retardants have overtaken  lead and mercury as leading contributors to IQ loss in children.

The researchers looked at exposure to major groups of endocrine disrupting chemicals during pregnancy and effects on the children. Yes - once again, chemicals frequently found all around us are hormone disruptors, and these chemicals also negatively affect neurological development. One result with higher exposure is that it lowers IQ. The 4 groups are: flame retardants (polybrominated diphenyl ethers or PBDEs), certain pesticides (organophosphates), mercury (methymercury), and lead. Exposures to the first three have the biggest effect during pregnancy (they cross the placenta and so get to the baby).

The researchers found an interesting result: organophosphate pesticide (such as chlorpyrifos) exposure and IQ loss attributed to it has increased since 2003. And that since the EPA did not ban chlorpyrifos (widely used on crops), then organophosphate pesticide "levels will continue to climb in the United States population due to ingestion of chlorpyrifos-treated crops". NOTE: these pesticides are allowed on conventional crops, but NOT organic crops.

How to avoid exposure? Hard to totally avoid exposure to these chemicals, but you can lower your exposure. Eat as many organic foods as possible. Try to avoid buying or having flame retardant sofas, upholstered chairs, and other upholstered furniture in your home. [Note: if they say that they use "safer" replacement chemicals - still avoid that furniture. The replacements are similar chemicals and may be just as bad or worse.] Frequently open windows to "air out" the home.

More bad news about the toxic class of chemicals called PFAS chemicals, which are used in a wide variety of consumer products, such as Teflon non-stick cookware and Scotchgard. The problem is that the chemicals don't stay in the products, but leach out (migrate out) and spread further - even into us. Unfortunately these chemicals persist in the environment. Earlier studies had already detected PFAS  (per- and polyfluoroalkyl substances) chemicals in water, soil, some foods, and in the bodies of almost all Americans. Now some recent research studies and the efforts of investigative journalists have uncovered more disturbing findings about the spread of these chemicals in the environment, in foods, and us.

The site Intercept has done a series of investigative reports highlighting these new findings about PFAS chemicals For example, these chemicals are found in fertilizers that contain sewage sludge (or biosolids) that farmers use on their farms. Farmers have been been doing this for decades. And it's in milk from dairy farms that spread this compost (fertilizer) made from sewage sludge on their fields. Of course! What is spread on the fields gets into food and which humans then ingest. The chemicals are also found in breastmilk from women in every country that has been studied.

Environmental Working Group (EWG) also has a series of articles on these chemicals, including the results of a recent FDA study of foods. The FDA found PFAS in many foods, including meat, seafood, dairy products, sweet potatoes, pineapples, leafy greens, and chocolate cake with icing. But the FDA has not publicly disclosed the results. Why not? Especially since the EPA has already said that "dietary exposure" (what we eat) is a main way that people get these chemicals into their bodies.

Why should we be concerned? PFAS chemicals are called  by some as "persistant chemicals" because of their persistence in the environment and humans. PFAS chemicals are linked to all sorts of serious health risks, including reproductive harm (e.g.poorer semen quality), cancers, lowered sex and growth hormones in children, immune effects,  thyroid disease, liver and kidney damage, and high cholesterol.

PFAS chemicals (such as PFOA, PFOS, PFBS) are used in a wide variety of consumer products because they have stain, water, and grease repellent properties. They are used in nonstick cookware, in food packaging (especially the paper wrappers and cardboard containers), stain-resistant carpets, furniture, floor waxes, textiles, water-proof and stain-resistant clothing (such as Gore-tex fabric), and performance gear. Remember Teflon? That's one. Some have been banned, phased out of use because of their dangers, but the replacements appear to be just as bad. The chemicals migrate out of food packaging into food, or can be released into the air and dust from carpets and upholstery treated with stain-resistant coatings.

I want to point out that sewage sludge (also called biosolids), are found in many commonly available fertilizers, such as Milorganite fertilizer.  It's not just farmers who've been using the stuff for years. Note that organic fertilizers and organic farmers can NOT use sewage sludge (biosolids). It turns out that even compostable food containers contain PFAS chemicals that leach out. Yikes!

What can you do to lower exposure to PFCs? These are chemicals that are hard to totally avoid, but one can lower exposure to them. And some have been phased out. The good news is that research shows that after a while levels in blood and breast milk should drop. What to do?? First of all, don't use non-stick pots and pans, and definitely not older Teflon ones. Use stainless steel or cast iron instead. Avoid the use of non-stick smooth dental floss made with a "non-stick" coating such as Oral-B Glide dental floss (use plain waxed or unwaxed floss instead). Try to not eat prepared foods in coated containers frequently. Avoid Scotchgard or other stain-proofing or stain-resistant treatments on upholstered furniture or rugs. Avoid water-proof treated fabric. It's also best to avoid drinking PFAS-contaminated water (which may be hard to do in places such as NJ where so much of the water supply is contaminated by PFAS chemicals).

Published on Leave a comment on What’s Getting Into You From Vinyl Flooring?

Many of us have concerns over the fact that people are constantly exposed to endocrine disruptors (chemicals that disrupt hormonal systems) in many common household and personal products. Even the vinyl flooring found in many homes  contains phthalates, which are endocrine disrupting chemicals.

In the past year several studies have looked at vinyl flooring in homes and whether the chemicals in the flooring outgas into the air and then get into people living in the homes. The answer is YES - the chemicals in vinyl flooring do get into people living there, and they can be measured in urine (in the breakdown products of phthalates called metabolites).

Since research shows that endocrine disrupting chemicals have health effects, then the question is: Do chronic low levels do anything to people? Especially worrisome is, are they having an effect on the developing fetus when pregnant women are exposed to them and they get into the body?

The following 2 studies looked at flooring, but keep in mind that we are exposed to phthalates in many, many products - e.g., plastic shower curtains, plastic food containers, some personal care products, household products. The problem is that the pthalates migrate out of the plastic products - they don't stay in the product. In the case of vinyl flooring - one can say that there are phthalate emissions from the flooring! And of course it gets into household dust.

Numerous studies found that phthalates (the phthalate metabolites) are routinely found in people of all ages - throughout the world. It can be measured in our blood (serum) and in our urine. Studies find them in breastmilk and also in amniotic fluid. Research finds associations associations between exposure to several phthalates and various effects on human health, including reproductive effects.

The following are two complementary studies. Study 1 looked at vinyl flooring (called PVC flooring in the article) in homes (in the kitchen and bedrooms), and found that phthalates get into pregnant women, and can be measured in the urine. Study 2 (from Duke University), found that chemicals children are exposed to in the home from vinyl flooring and the sofa (flame-retardants) can be measured in their blood and urine. The researchers took all sorts of samples from homes and children over a 3 year period and found evidence in the children of exposure to phthalates, organophosphate esters, brominated flame retardants, parabens, phenols, antibacterial agents and perfluoroalkyl and polyfluoroalkyl substances (PFAS).

So we have proof that these chemicals are getting into us. We can't avoid them totally, but can lower our exposure levels - look for upholstered furniture without flame retardants (read the label!), and don't install vinyl flooring (wood and tile floors are OK).  ...continue reading "What’s Getting Into You From Vinyl Flooring?"

Published on Leave a comment on New Book Warning Us About Endocrine Disruptors

The following is a really nice article about endocrine disruptors (chemicals that can interfere with the body's hormonal system). Journalist Hillary Brueck writes about where they are found (all around us!), some of the many negative health effects, and about NYU physician and researcher Dr. Leonardo Trasande and his new book: "Sicker, Fatter, Poorer: The Urgent Threat of Hormone-Disrupting Chemicals to Our Health and Future ... and What We Can Do About It." Also, some things we can do to lower our exposure to endocrine disruptors.

By the way, once again Europe is ahead of the US in dealing with this problem. Excerpts from Business Insider: A toxic-chemicals expert is sounding the alarm about 4 cancer-linked chemicals that could be making us sicker and fatter

Through the course of a single day, your hands, mouth, and body come in contact with countless pieces of paper, plastic, fabric, and furniture. You probably don't think about the chemicals these substances might harbor, or consider that they have a drug-like effect on health. But some do. They can make metabolisms slow down, subtly lower IQs, contribute to ADHD in children, and mess with sperm counts in men.

They're called "endocrine disruptors," and they're around us all the time. The chemicals change how our bodies work by shifting the way hormones operate, according to Leo Trasande, a pediatrician and public-health researcher at NYU Langone Health. "Hormones are the basic signaling molecules in our body that take on so many actions for practically every organ system," Trasande told Business Insider. "And endocrine disruptors are synthetic chemicals that scramble those signals, contributing to disease and disability."

In his new book, "Sicker, Fatter, Poorer: The Urgent Threat of Hormone-Disrupting Chemicals to Our Health and Future ... and What We Can Do About It," Trasande lays out the four big categories of endocrine disruptors he's most concerned about, based on evidence from scientific studies and observations in his patients. They are: Bisphenols, like BPA, which are often found in the linings of aluminum-canned food and drinks and on cash-register receipts. Brominated flame retardants that are in some carpets, furniture, and clothing. Synthetic pesticides on food. "Plasticizer chemicals" called phthalates that show up in plastic food packaging, lotions, and cosmetics.  ...continue reading "New Book Warning Us About Endocrine Disruptors"

Published on Leave a comment on Study Finds That Simple Steps Lower Flame Retardant Levels In the Body

Flame retardants are a big, big concern nowadays, with their links to all sorts of health problems, including endocrine disruption, cancer, reproductive problems, etc. (here) And it's hard to avoid them - they're in products all around us, including the upholstered furniture and electronics that most people have in their homes. They leach or "migrate" out of the products, enter into the air, and settle as dust particles in our homes, and in the process get into us - from inhalation and ingestion of the dust. So we can't fully avoid them... but we can drastically reduce the amounts we get into us fairly quickly as a recent study showed.

The study (of 32 mothers living in New York City) found that more frequent hand washing and more frequent house cleaning for one week reduced flame retardant levels - as measured in the urine. About 50% reductions after one week! And yes, all women had flame retardants in their urine - some of which they were able to reduce, but not eliminate. Earlier research by most of this same group of researchers found that every toddler tested (25 toddlers living in New York City) had flame retardants (from dust) on their hands.

The US EPA says that dust is the major way humans are exposed to flame retardants. They suggest the following steps be taken to lower flame retardant exposure, especially if one has young children: frequent hand washing (especially before eating), dust frequently with a moist cloth, frequently wet mop or vacuum with a  vacuum cleaner that has a HEPA filter, and repair tears to upholstered furniture. The study confirms that these steps work.

And please, if buying new upholstered furniture such as sofas, or rugs, or curtains, or some baby products - look at the label to make sure it doesn't contain flame retardants. Even the newer flame retardants that manufacturers claim are "safer" are still chemically related to the old versions, and have the same health concerns. From Medical Xpress:

Handwashing and house cleaning may protect against unhealthy chemicals

Washing your hands and cleaning your house frequently may help to lower your contact with common flame-retardant chemicals, according to a new study by researchers at the Columbia Center for Children's Environmental Health (CCCEH) at Columbia University's Mailman School of Public Health.

Published on Leave a comment on Can We Avoid the Endocrine Disruptors Around Us?

Today I am posting the story of one person writing about how hard it is to reduce contaminants, that is, unwanted chemicals, in our bodies. The story is by Nicholas Kristof, who has been eating organic foods and trying his best to avoid endocrine (hormone) disrupting chemicals (such as BPA) for a number of years. But the analysis of his urine showed that he wasn't able to totally avoid them.

This also raises the question - how many more unwanted chemicals would have been in his body if he hadn't been so diligently trying to avoid them? And as usual, the question remains - what are all these chemical mixtures doing to him and to us? How about developing fetuses and children? To men and women trying to conceive a baby? To the ill and elderly? Right now an experiment is going on in the world, one which we can't escape - chemicals, including endocrine disruptors (all produced by the chemical industry) are being tested on us (the research subjects). For more information on this topic, click on category ENDOCRINE DISRUPTORS and scroll through the posts, or go to Environmental Working Group - ewg.org, or get a Detox Me Action Kit from the Silent Spring Institute (and get your urine analyzed).  Excerpts from the article by Nicholas Kristof, from the NY Times:

What Poisons Are In Your Body?

Published on Leave a comment on Flame Retardants And Reduced IQ In Children

A new study that analyzed other studies (a meta-analysis) found that the class of flame retardant chemicals called PBDEs (commonly found in furniture and household products) has an effect on children's intelligence, so that it results in a loss of IQ points. Most of the studies looked at the child's exposure to flame retardants during pregnancy and then later IQ. They found that the child's IQ was reduced by 3.70 points for each ten-fold increase in flame retardant levels (thus, the higher the PBDE levels, the greater the effect on the child's IQ). This is of concern because flame retardants are in so many products around us, both in and out of the home. Older flame retardants (PBDEs) were phased out by 2013, but it turns out that the newer replacements (TBB and TBPH, including Firemaster 550) also get into people and also have negative health effects.

More and more research is finding health problems with flame retardants because they are "not chemically bound" to the products in which they are used - thus they escape over time. and get into us via the skin (dermal), inhalation (from dust), and ingestion (from certain foods and dust on our fingers). And because flame retardants are persistant, they bioaccumulate (they build up over time). They can be measured in our urine and blood. Evidence suggests that flame retardants may be endocrine disruptors, carcinogenic, alter hormone levels, decrease semen quality in men, thyoid disruptors, and act as developmental neurotoxicants (when developing fetus is exposed during pregnancy)  so that children have lowered IQ and more hyperactivity behaviors.

Where are flame retardants found? All around us, and in us. They are so hard to avoid because they're in electronic goods, in upholstered furniture, polyurethane foam, carpet pads, some textiles, the foam in baby items (car seats, bumpers, crib mattresses, strollers,nursing pillows, etc.), house dust, building insulation, and on and on. What to do? Wash hands before eating. Try to use a vacuum cleaner with a HEPA filter. Try to avoid products that say they contain "flame retardants". Only buy upholstered furniture with tags that say they are flame retardant free. The California Childcare Health Program has an information sheet on how to lower exposure to fire retardants. From Medical Xpress:

Flame retardant exposure found to lower IQ in children

A hazardous class of flame retardant chemicals commonly found in furniture and household products damages children's intelligence, resulting in loss of IQ points, according to a new study by UC San Francisco researchers. The study, published Aug. 3, 2017, in Environmental Health Perspectives, included the largest meta-analysis performed on flame retardants to date, and presented strong evidence of polybrominated diphenyl ethers' (PBDE) effect on children's intelligence. Despite a series of bans and phase-outs, nearly everyone is still exposed to PBDE flame retardants, and children are at the most risk," said UCSF's Tracey Woodruff, professor in the Department of Obstetrics, Gynecology and Reproductive Sciences..... 

The findings go beyond merely showing a strong correlation: using rigorous epidemiological criteria, the authors considered factors like strength and consistency of the evidence to establish that there was "sufficient evidence" supporting the link between PBDE exposure and intelligence outcomes. Furthermore, a recent report by the National Academies of Sciences endorsed the study and integrated evidence from animal studies to reach similar conclusions that PBDEs are a "presumed hazard" to intelligence in humans.

Researchers examined data from studies around the world, covering nearly 3,000 mother-child pairs. They discovered that every 10-fold increase in a mom's PBDE levels led to a drop of 3.7 IQ points in her child." "Many people are exposed to high levels of PBDEs, and the more PBDEs a pregnant woman is exposed to, the lower her child's IQ," said Woodruff. "And when the effects of PBDEs are combined with those of other toxic chemicals such as from building products or pesticides, the result is a serious chemical cocktail that our current environmental regulations simply don't account for." The researchers also found some evidence of a link between PDBE exposures and attention deficit hyperactivity disorder (ADHD), but concluded that more studies are necessary to better characterize the relationship.

PBDEs first came into widespread use after California passed fire safety standards for furniture and certain other products in 1975. Thanks to the size of the Californian market, flame retardants soon became a standard treatment for furniture sold across the country..... Mounting evidence of PDBEs' danger prompted reconsideration and starting in 2003 California, other states, and international bodies approved bans or phase outs for some of the most common PBDEs. PBDEs and similar flame retardants are especially concerning because they aren't chemically bonded to the foams they protect. Instead, they are merely mixed in, so can easily leach out from the foam and into house dust, food, and eventually, our bodies. [Original study.]

Published on Leave a comment on Steep Decline In Sperm Counts In Western Men

Once again a study (this time a review and meta-analysis of other studies) found an alarming and steep decline in sperm counts in men from Western countries over a 40 year period. This steep decline for both sperm concentration (SC) and total sperm count (TSC) is for men in North America, Europe, Australia, and New Zealand. The sperm count and sperm concentration declined 50 to 60% in the period between 1973 to 2011 - with a downward slope showing a decline of -1.4% to -1.6% per year. On the other hand, men from South America, Asia and Africa did not show a decline.

The authors of the study were very concerned over the results showing this decline in Western countries, with no evidence of the decline leveling off. As these declines continue, more and more men will have sperm counts below the point at which they can reproduce. Instead they will be infertile or "sub-fertile" (with a decreased probability of conceiving a child). The threshold level associated with a "decreased monthly probability of conception" is considered to be 40 million/ml.

Shockingly - this study found that in 1973 when Western men who were not selected for fertility, and didn't know their fertility status (e.g., college students, men screened for the military) - the average sperm concentration was 99 million/ml, but by 2011 it was 47.1 million/ml. These men were called "unselected" and are likely to be representative of men in the general population. Men known to be fertile (e.g., had fathered a child) were at 83.8 million/ml in 1976, but were down to 62.0 million/ml in 2011. Both groups had consistent declines year after year.

What about the men from South America, Asia, and Africa? There, studies showed that the "unselected" men (not selected for fertility and who didn't know their fertility status) started out at 72.7 million/ml in 1983, and were at 62.6 million/ml in 2011, while men known to be fertile started out on average at 66.4 million/ml in 1978 and were at 75.7 million/ml in 2011. They did not show the decline of the North American, European, Australian, and New Zealand group of men.

What does this mean? And what is going on? These results go beyond fertility and reproduction. The decline is consistent with other male reproductive health indicators over the last few decades: higher incidence of testicular cancer, higher rates of cryptorchidism, earlier onset of male puberty, and decline in average testosterone levels. Instead, it appears that sperm counts of men are "the canary in the mine" for male health - evidence of harm to men from environmental and lifestyle influences.

These Western developed countries are awash in chemicals and plastics, also with endocrine disruptors (hormone disruptors) in our foods, our personal care products, etc - and so studies find these chemicals in all of us (in varying degrees). Same with flame retardants, pesticides, "scented" products. Exposure to all sorts of environmental pollutants - whether in air, water, soil, our food - such as high levels of aluminum. All of these can have an effect on sperm counts and reproductive health.

And note that chemicals that can depress sperm counts  are also linked to many health problems, including chronic diseases.

What can you do?  You can lower your exposure to many chemicals (e.g., pesticides), plastics, and endocrine disruptors, but you can't avoid them totally. Yes, it'll mean reading labels and ingredient lists on foods, personal care products (such as soaps, shampoo, lotion), and products used in the home. [LIST OF THINGS YOU CAN EASILY DO]

TRY TO AVOID OR LOWER EXPOSURE TO: phthalates, parabens, BPA, BPS, and even BPA-free labeled products (all use similar chemicals), flame-retardants (e.g., in upholstered furniture and rugs), stain-resistant, dirt-resistant, waterproof coatings, Scotchgard, non-stick cookware coatings, dryer sheets, scented products (including scented candles and air fresheners), fragrances, pesticides in the yard and home, and "odor-free", antibacterial, antimicrobial, anti-mildew products. Don't microwave foods in plastic containers (including microwave popcorn bags). 

INSTEAD: Try to eat more organic foods, look for organic or least-toxic Integrated Pest Management (IPM) alternatives for the home and garden. Store foods as much as possible in glass, ceramic, or stainless steel containers. Buy foods, if possible, that are in glass bottles - not cans (all lined with endocrine disrupting chemicals) and not plastic bottles or containers (plastics leach). Some people use water filters because there are so many contaminants in our water, even if they meet federal guidelines on "allowable levels" in the water.

Avoid cigarette smoke or smoking. Try to lose weight if overweight. Open windows now and then in your residence to lower indoor air pollution. The list is long - yes, a lifestyle change! (see posts on ENDOCRINE DISRUPTORS, FLAME RETARDANTS, and PESTICIDES)

From Medical Xpress: Study shows a significant ongoing decline in sperm counts of Western men

In the first systematic review and meta-analysis of trends in sperm count, researchers from the Hebrew University-Hadassah Braun School of Public Health and Community Medicine and the Icahn School of Medicine at Mount Sinai report a significant decline in sperm concentration and total sperm count among men from Western countries.

By screening 7,500 studies and conducting a meta-regression analysis on 185 studies between 1973 and 2011, the researchers found a 52.4 percent decline in sperm concentration, and a 59.3 percent decline in total sperm count, among men from North America, Europe, Australia and New Zealand who were not selected based on their fertility status. In contrast, no significant decline was seen in South America, Asia and Africa, where far fewer studies have been conducted. The study also indicates the rate of decline among Western men is not decreasing: the slope was steep and significant even when analysis was restricted to studies with sample collection between 1996 and 2011.

The findings have important public health implications. First, these data demonstrate that the proportion of men with sperm counts below the threshold for subfertility or infertility is increasing. Moreover, given the findings from recent studies that reduced sperm count is related to increased morbidity and mortality, the ongoing decline points to serious risks to male fertility and health.

"Decreasing sperm count has been of great concern since it was first reported twenty-five years ago. This definitive study shows, for the first time, that this decline is strong and continuing. The fact that the decline is seen in Western countries strongly suggests that chemicals in commerce are playing a causal role in this trend," Dr. Shanna H Swan, a professor in the Department of Environmental Medicine and Public Health at the Icahn School of Medicine at Mount Sinai, New York.

While the current study did not examine causes of the observed declines, sperm count has previously been plausibly associated with environmental and lifestyle influences, including prenatal chemical exposure, adult pesticide exposure, smoking, stress and obesity. Therefore, sperm count may sensitively reflect the impact of the modern environment on male health across the lifespan and serve as a "canary in the coal mine" signaling broader risks to male health. [Original study.]

Flame retardants are in many products around us, both in and out of the home, but there is much concern over their health effects on humans. Older flame retardants (PBDEs) were phased out by 2013, but it turns out that the newer replacements (TBB and TBPH, including Firemaster 550) also get into people and also have negative health effects. So it shouldn't be a surprise that every single toddler tested in a study in New York City showed evidence of flame retardants on their hands (both the old kind and newer replacements), and that they had more on their hands than their mothers. Flame retardants were also found in all house dust samples. Since they are linked to many negative health effects, you really, really want to minimize the amounts in your body.

More and more research is finding health problems with flame retardants because they are "not chemically bound" to the products in which they are used - thus they escape over time. and get into us via the skin (dermal), inhalation (from dust), and ingestion (from certain foods and dust on our fingers).

NYC toddlers exposed to potentially harmful flame retardants

Evidence of potentially harmful flame retardants on the hands and in the homes of 100 percent of a sample of New York City mothers and toddlers has been uncovered by researchers. The study also found that on average toddlers in New York City had higher levels of common flame-retardants on their hands compared to their mothers.

Researchers at the Columbia Center for Children's Environmental Health (CCCEH) within the Mailman School of Public Health report evidence of potentially harmful flame retardants on the hands and in the homes of 100 percent of a sample of New York City mothers and toddlers. The study also found that on average toddlers in New York City had higher levels of common flame-retardants on their hands compared to their mothers. The Center's previous research has linked early life exposure to a common class of flame-retardants called PBDEs with attention problems and lower scores on tests of mental and physical development in children.

Beginning in the 1970s, manufacturers added PBDEs, persistent brominated flame-retardants, to couches, textiles, electronics and other consumer products to comply with flammability standards. They began phasing out PBDEs in 2004 and started using newer alternative flame-retardants, including TBB and TBPH, which are components of the commercial mixture Firemaster 550®. TBB and TBPH are brominated flame retardants for which little is known about their health effects in humans, though they have been linked to reduced fertility and endocrine disruption in animal models.

Researchers visited the homes of 25 mother-child pairs enrolled in the CCCEH Sibling-Hermanos birth cohort, which began in 2008. When children were 3 years old, dust was collected from their homes and hand wipes were collected from the mother and child; these samples were analyzed for flame retardant compounds....Results are consistent with other studies, which demonstrate that toddlers tend to have higher exposure to flame retardants when compared with adults, likely because of the amount of time they spend on the floor.

Published on Leave a comment on Exposure to Common Chemicals Costs the US $340 Billion Each Year

Many articles have been written about endocrine disrupting chemicals and the numerous health problems they're linked to (see posts on them). It's been known for decades that endocrine-disrupting chemicals pose a danger to human health because the compounds can interfere with natural hormone function. Chemical exposure occurs through routine contact with plastic bottles, vinyl items, toys, food cans, cosmetics, flame retardants, and other consumer products containing "endocrine-disrupting chemicals". We ingest, breathe them in (inhalation), or absorb them through the skin as consumer products are used and also as consumer products break down (the dust).

Finally a study examines the financial cost of these chemicals - an estimate of more than $340 billion annually due to health care costs and lost wages (the authors say this is a conservative estimate). What can ordinary people do to lower their exposure to these chemicals? Avoid the use of pesticides in the home, lawns, and gardens. Eat as much organic foods as possible. Avoid buying food in cans, including soda. Store food in glass and stainless steel containers. Avoid microwaving in plastic containers (use glass instead). Avoid plastic bottles with the numbers 3, 6, and 7 on the bottom. Avoid vinyl items such as vinyl shower curtains and vinyl toys. Avoid fragrances (get unscented products). Read labels on lotions, shampoos, soaps, make-up - avoid phthalates and parabens. Avoid flame retardants (check the labels on new upholstered furniture). Avoid non-stick pots, avoid stain-repellant items, avoid air fresheners and dryer sheets. And that's just a partial list....From Environmental Health News:

Toxic economy: Common chemicals cost US billions every year

Exposure to chemicals in pesticides, toys, makeup, food packaging and detergents costs the U.S. more than $340 billion annually due to health care costs and lost wages, according to a new analysis. The chemicals, known as endocrine disruptors, impact how human hormones function and have been linked to a variety of health problems such as impaired brain development, lower IQs, behavior problems, infertility, birth defects, obesity and diabetes. The findings, researchers say, "document the urgent public threat posed by endocrine disrupting chemicals.”   ...continue reading "Exposure to Common Chemicals Costs the US $340 Billion Each Year"
