People everywhere are dismayed by the sheer quantity and number of "forever chemicals" that contaminate our environment and our bodies. Unfortunately, we all have forever chemicals (PFOS, PFAS) in us (but in varying amounts). It turns out that the US government played a role in the forever chemicals found in our food, and why so many farms are now forever contaminated.

Decades ago, the US EPA (Environmental Protection Agency) started encouraging the use of biosolids or black sludge (the sludge that is left over at wastewater treatment plants) as a fertilizer on farms in the United States. That the use of this biosolid sludge could cause problems and harms has been known for decades.

The sludge contains heavy metals and PFOS and PFAS chemicals (forever chemicals because they bioaccumulate and persist in the environment). The chemicals are linked to all sorts of health harms (e.g., cancers, reproductive problems). [Note: We are exposed to forever chemicals in many products and in the environment daily.]

Well.... of course, applying this sludge across farms has now resulted in persistent contamination of both the soil and water at those farms, but also in the animals being raised on those farms. Estimates are up to a fifth of farms are contaminated. And yet the EPA still feels this practice of applying contaminated sludge is OK!!!

Very few mass media articles actually discuss the government's role in contaminating farms (and in this way our food). So the following 2 articles were a pleasant surprise - horrifying to read, but all true.

Bottom line: Eat as much organic food, or what you grew yourself, as much as possible. The biosolid sludge is not allowed on organic farms. Also, when buying top soil (dirt) or fertilizer for your garden, avoid any product that says "biosolids" in it. (e.g., Milorganite  - known to contain PFAS and PFOS) Buy organic soil and fertilizer, if you can.

Until recently, very few mass media articles actually discussed the government's role in contaminating farms (and in this way our food). So the following 2 articles are horrifying to read, but all true.

(1) Excerpts from the New York Times: Something’s Poisoning America’s Land. Farmers Fear ‘Forever’ Chemicals.

For decades, farmers across America have been encouraged by the federal government to spread municipal sewage on millions of acres of farmland as fertilizer. It was rich in nutrients, and it helped keep the sludge out of landfills.

But a growing body of research shows that this black sludge, made from the sewage that flows from homes and factories, can contain heavy concentrations of chemicals thought to increase the risk of certain types of cancer and to cause birth defects and developmental delays in children.

Known as “forever chemicals” because of their longevity, these toxic contaminants are now being detected, sometimes at high levels, on farmland across the country, including in Texas, Maine, Michigan, New York and Tennessee. In some cases the chemicals are suspected of sickening or killing livestock and are turning up in produce. Farmers are beginning to fear for their own health.

A fertilizer used for decades by U.S. farms contains toxic chemicals that are being blamed for halting agricultural operations, killing animals, and endangering our food supply. ...continue reading "The Government’s Role In Why Many Farms Are Contaminated With Forever Chemicals"

Intestines Credit: Wikipedia

A number of things can contribute to the development of colorectal cancer (colon cancer), such as highly processed foods, eating a Western diet low in fiber, or the bacteria Fusobacterium nucleatum. These are known to contribute to or result in the gut microbiome being out of whack (gut dysbiosis).

Another factor is perfluorooctanesulfonic acid (PFOS), which are chemicals we all are exposed to in everyday life. A recent study illustrated how long-term exposure to PFOS can also contribute to the development of colorectal cancer because of the effect it has on intestinal cells in the intestines.

PFAS and PFOS (Per- and polyfluoroalkyl substances) are called forever chemicals due to their buildup (bioaccumulation) and persistence in people and the environment. We get exposure to these chemicals various ways - through ingestion (food and water), inhalation (dust), and from absorption through the skin (e.g., personal care products).

They are widely used chemicals, such as in non-stick coatings (e.g., pots and pans) and stain and water repellent products. We get exposure to these chemicals various ways - through ingestion (food and water), inhalation (dust), and from absorption through the skin (e.g., personal care products).

They are in all of us at varying levels, and they have harmful health effects. Effects include cancer, reproductive harm (e.g., poorer semen quality), birth defects, lowered sex and growth hormones in children, thyroid disease, immune effects, and liver and kidney damage. They are endocrine disruptors.

The chemical industry would have you think that the newer PFAS chemicals that replace the older ones are "safer", but guess what? They're not. They're very similar chemically, so it shouldn't be surprising that they don't appear to be safer.

Bottom line: You can't totally avoid PFAS chemicals, but you can lower your exposure to them. If possible, avoid products that are water and stain proof or leak-proof, especially if children will be using the product. Don't use nonstick cookware, stain resistant carpeting and fabrics, clothing treated to be water-proof, and synthetic turf. PFAS and PFOS don't have to be mentioned on labels, so it's buyer beware.

A recent University of Kentucky Markey Cancer Center study sheds light on how the environmental pollutant perfluorooctanesulfonic acid (PFOS) may affect our intestines and possibly increase the risk of developing colorectal cancer. ...continue reading "Forever Chemicals Are Linked To Colorectal Cancer"

3M Company Credit: Wikipedia

Forever chemicals are in the news all the time now. A very interesting and well-researched article was recently published by the investigative journalism site ProPublica about Kris Hansen, a chemistry PhD who worked at 3M company. Initially, as part of her job in 1997, she documented that forever chemicals (PFOS, PFAS) were showing up in everyone's blood - both workers at the company, as well as people outside the company. Animals also. But then her work was suppressed, her bosses at 3M convinced her the chemicals were safe, and she continued working there for years.

Also... she was sidelined by her bosses after her initial findings, her job became more limited at the company, and finally she moved to a different area of the company (medical devices). Yet for years she told her husband and herself that the chemicals were safe. Only in 2021, after watching a John Oliver segment on TV about forever chemicals, she finally googled PFOS. But she only left the company in 2022 (after 26 years) when her job was eliminated.

One interesting part to me was - How did she rationalize doing nothing and continue working there for decades? She knew it was appearing in everyone's blood, there was research (animal and human) available showing it caused harms, and yet.... she chose to believe what management was saying (it's safe), stayed silent, and basically buried her head in the sand. Didn't want to know...

Yes, I've seen this elsewhere - when interacting with people in higher level white collar jobs in the pesticide industry. Their salaries are good, their jobs depend on denialism and ignoring scientific research, and so they spout the industry line of "it's safe"..."nothing is proven". So it continues...

A few excerpts from ProPublica: Toxic Gaslighting: How 3M Executives Convinced a Scientist the Forever Chemicals She Found in Human Blood Were Safe

The next morning, anxious to see the results, Hansen arrived at the lab before anyone else. For the first time since she had begun testing blood, some of the samples showed no trace of PFOS. She was so struck that she called her husband. There was nothing wrong with her equipment or methodology; PFOS, a man-made chemical produced by her employer, really was in human blood, practically everywhere. ...continue reading "Denialism and Cover-up At Manufacturer Of Forever Chemicals"
