kkrisberg | January 31, 2014In a first-of-its-kind study, a researcher has estimated that the health-related economic savings of removing bisphenol A from our food supply is a whopping $1.74 billion annually. And that’s a conservative estimate.
“This study is a case in point of the economic burden borne by society due to the failure to regulate environmental chemicals in a proactive way,” study author Leonardo Trasande told me.
With evidence mounting that bisphenol A (BPA) exposure is a serious health risk, Trasande, an associate professor in pediatrics, environmental medicine and health policy at New York University,…
cmonforton | December 12, 2012A recently published case-control study involving more than 2,100 women in southern Ontario, Canada reported a strong association between being employed in the automotive plastics industry and breast cancer. The researchers recruited the 'case' subjects between 2002-2008 among newly diagnosed breast cancer patients and the randomly-selected controls from the same geographic area. The researchers examined a variety of risk factors for breast cancer (e.g., reproductive history, age) and collected data on the women's employment history. Elevated odds of breast cancer were found among women…

I've been telling you about the perils of plastics, but some of the worst plastics offenders are molecular and cell biologists. Nearly every experiment that we do uses incredible amounts of plastics. In cell biology or molecular biology labs the emphasis is on working sterile, quickly and reproducibly. So companies have been selling all these incredibly useful products to life science labs: sterile plastic tubes of all shapes and sizes, single wrap multi-well tissue culture plates, sterile plastic dishes, sterile…

This is a message by Captain Charles Moore, an oceanographer who pioneered the study of plastic debris, and was recorded during the Strategic Council on Plastic Pollution convened at the Google Campus in Mountain View, California on June 4, 2009. It was the first meeting for the council on plastic pollution, which was recently formed to raise awareness of this rising threat to the world's oceans. Council member and marine biologist Dr. Wallace J. Nichols, noted that "we are finding plastic in the stomachs of sea turtles,…

The center of the North Pacific Gyre is a relatively stationary region of the Pacific Ocean (the area it occupies is often referred to as the horse latitudes). The circular rotation around it draws waste material in and has led to the accumulation of flotsam and other debris. While historically this debris has biodegraded, the gyre is now accumulating vast quantities of plastic and marine debris. Rather than biodegrading, plastic photodegrades, disintegrating in the ocean into smaller and smaller pieces. These…
