The hits keep coming against plastic bottles with bisphenol-A

Bisphenol A in 3-D from Adiaha.comThe hits keep coming against bisphenol-A (BPA), a chemical used in plastics we come in contact with every day.

BPA was, until recently, used in most Nalgene bottles found on workers’ desk and in baby bottles, as well as food containers. Some 93% of us have detectable levels of this in our bodies.

The latest hit is a study from the Yale School of Medicine, which gave monkeys what the EPA considers a “safe” dose of the chemical and found negative impacts on mood and memory.

“Our primate model indicates that BPA could negatively affect brain function in humans,” said study co-author Tibor Hajszan, M.D., associate research scientist in Yale Ob/Gyn. “Based on these new findings, we think the EPA may wish to consider lowering its ‘safe daily limit’ for human BPA consumption.”

But this comes just as the National Institutes of Health has come out with a limited all-clear on BPA. The National Toxicology Program says there is still “some concern” about BPA but has not recommended any action be taken.

Many of America’s headline writers agree:

Someone check these folks’ water bottles. Tests of BPA done with doses now present in your body show reduction in brain function from this chemical. Not just in babies, but in adult primates.
