A study was conducted using adult female Gobiocypris rarus, a rare minnow. The fish were exposed to 5 μg/L, 15μg/L and 50 μg/L of BPA for 14 days and 35 days. [117] The results showed the group exposed to the highest amount of BPA (50 μg/L) for 35 days showed suppressed effects on oocyte development. [117]
[97] [106] [107] Its half life in water has been estimated at between 4.5 and 15 days, degradation in the air is faster than this, while soil samples degrade more slowly. [100] BPA in sediment degrades most slowly of all, particularly where this is anaerobic. Abiotic degradation has been reported, but is generally slower than biodegradation.
In this study the human breast epithelial cells MCF-10F were treated with 10-3 M, 10-4 M, 10-5 M and 10-6 M BPA continuously for two weeks. The cells treated with 10-3 M BPA died on the second day of treatment. The concentration of 10-4 M BPA was also toxic for the breast epithelial cells, and they died on the fourth day of treatment.
Bisphenol A (BPA), phthalates, and per- and polyfluoroalkyl substances (PFAS) are just a few of the chemicals known to imitate hormones and disrupt the body’s natural endocrine system, which is ...
A leading environmental group has sued the Food and Drug Administration for dragging its feet on its request 20 months ago to ban the use of bisphenol A (BPA), a toxic chemical, in food packaging.
The same goes for vitamin B12 and ferritin (a form of iron) which women may not get enough of via food, particularly those following plant-based or vegetarian diets.

As researchers later discovered, the original research studied women who were 65 and up who already had a greater risk of heart attack, stroke, blood clots and more. As a result, it skewed the ...
