Two recent studies point out the dangers of air pollution to the developing fetus. The first study found an association with high levels of air pollution during pregnancy and lower IQ years later when the children were between the ages of 4 to 6 (as compared to women exposed to less traffic-related air pollution during ...continue reading "Air Pollution Has Harmful Effects During Pregnancy"
Researchers measured chemicals in the air in 2 cities (Boulder, CO and Toronto, Canada) and found equally high levels of 2 chemicals in the air during morning commute times - benzene (from vehicle exhaust) and a type of siloxane (from personal care products). What? This study's results make a strong case for reading ingredient lists of ...continue reading "Personal Care Products and Air Pollution"
Uh-oh, it looks like some (many?) new or fairly new kitchen cabinets are outgassing several types of PCBs from the wood sealants used on the cabinets. PCBs (polychlorinated biphenyls) were banned in the 1970s due to health risks - for example, they are known carcinogens, and some are neurotoxic (also here). Researchers from the University ...continue reading "Kitchen Cabinet Sealants Can Be A Source of Indoor Air Pollution"
I recently read a nice article discussing indoor air pollution, which can be worse than outdoor air, even that of cities. Yes, that's true! In past posts I've discussed problems (and health issues) with air fresheners, fragrances, incense, dryer sheets, scented candles, synthetic rugs, "stain-proofing", and flame retardants in upholstery, but this article is about furniture and ...continue reading "Furniture Can Be A Cause of Indoor Air Pollution"
Air pollution is linked to so many negative health effects, now another one - poorer quality sperm. In this study 6475 males (ages ranged from 15–49 years) had their sperm analyzed as part of a standard medical examination program in Taiwan. They were also able to get air pollution measurements for each person's address for ...continue reading "Air Pollution Has an Effect On Sperm?"
A study of 60 million Americans 65 years old and older (the entire Medicare population) found that long-term exposure to airborne fine particulate matter (PM2.5) and ozone at concentrations below current national standards increases the risk of premature death ("all cause mortality") even when the levels are below current national standards. This effect was most pronounced ...continue reading "Older Adults, Air Pollution, and Premature Death"
The use of nanomaterials has been really increasing in recent years without us really understanding if nanoparticles have negative health effects, and if they travel to the brain or other organs in the human body. Nanoparticles are used in many consumer products, including foods (e.g., nano-sized titanium dioxide) and medicines, but they are also found ...continue reading "Nanoparticles in Air Pollution Travel From Lungs to Bloodstream?"
Another study finding a link between air pollution and negative health effects - this time a higher incidence of decline in cognitive functioning and dementia in older women (65 and older) exposed to fine particles (PM2.5 ). These extremely small particles from vehicle emissions are a major source of urban air pollution throughout the world. ...continue reading "Air Pollution, the Aging Brain, and Dementia"
Study after study finds negative health effects from air pollution, such as heart disease (here, here, and here). Now two more studies found that living in areas with high air pollution is linked to a higher stroke risk. One study (done in Japan) found an increase of ischemic stroke on the same day as exposure ...continue reading "Air Pollution Linked To Strokes"
An new analysis of published studies found that air pollution is linked to high blood pressure. Yes, breathing polluted air has health effects (here, here, and here). From Science Daily: High blood pressure linked to short-, long-term exposure to some air pollutants Both short- and long-term exposure to some air pollutants commonly associated with coal ...continue reading "Air Pollution Linked to High Blood Pressure"
