The truth of the matter is, plastics are poisonous. Just giving up bottles of water and their BPAs is not nearly enough to avoid the health risks from plastic products, according to new research. Jon Hamilton has part of the story for NPR (and I say part, because estrogenic chemicals are only part of the problem):
Most plastic products, from sippy cups to food wraps, can release chemicals that act like the sex hormone estrogen, according to a study in Environmental Health Perspectives.
The study found these chemicals even in products that didn’t contain BPA, a compound in certain plastics that’s been widely criticized because it mimics estrogen.
But it’s still unclear whether people are being harmed by BPA or any other so-called estrogenic chemicals in plastics. Most studies of health effects have been done in mice and rats.
The new study doesn’t look at health risks. It simply asks whether common plastic products release estrogen-like chemicals other than BPA.
The researchers bought more than 450 plastic items from stores including Walmart and Whole Foods. They chose products designed to come in contact with food — things like baby bottles, deli packaging and flexible bags, says George Bittner, one of the study’s authors and a professor of biology at the University of Texas, Austin.
Then CertiChem, a testing company founded by Bittner, chopped up pieces of each product and soaked them in either saltwater or alcohol to see what came out.
The testing showed that more than 70 percent of the products released chemicals that acted like estrogen. And that was before they exposed the stuff to real-world conditions: simulated sunlight, dishwashing and microwaving, Bittner says.
“Then, you greatly increase the probability that you’re going to get chemicals having estrogenic activity released,” he says, adding that more than 95 percent of the products tested positive after undergoing this sort of stress…
