"BPA is one of many man-made chemicals classified as endocrine disruptors, which alter the function of the endocrine system by mimicking the role of the body's natural hormones. Hormones are secreted through endocrine glands and serve different functions throughout the body.
The chemical--which is widely used in products such as reusable water bottles, food can linings, water pipes and dental sealants--has been shown to affect reproduction and brain development in animal studies."
"BPA is just one of many estrogen-like chemicals people are exposed to, and scientists are still trying to figure out how these endocrine disruptors--including natural phyto-estrogens from soy which are often considered healthy--collectively impact human health," he says. "But a growing body of scientific evidence suggests it might be at the cost of your health."
Hormone-Mimics In Plastic Water Bottles Act As Functional Estrogens

"They analyzed 20 brands of mineral water available in Germany – nine bottled in glass, nine bottled in plastic and two bottled in composite packaging (paperboard boxes coated with an inner plastic film). The researchers took water samples from the bottles and tested them for the presence of estrogenic chemicals in vitro. They then carried out a reproduction test with the New Zealand mud snail to determine the source and potency of the xenoestrogens.
They detected estrogen contamination in 60% of the samples (12 of the 20 brands) analyzed. Mineral waters in glass bottles were less estrogenic than waters in plastic bottles. Specifically, 33% of all mineral waters bottled in glass compared with 78% of waters in plastic bottles and both waters bottled in composite packaging showed significant hormonal activity."

"Baby feeding bottles and other everday plastic items could be causing serious harm"

BPA has been linked to adverse effects on male reproduction, altered immune system function, behavioral changes, learning disabilities, brain damage and an increased chance for certain cancers. Researchers are most concerned about the exposure of babies to the chemical. "The science is clear and the findings are not just scary, they are horrific," vom Saal said. "When you feed a baby out of a clear, hard plastic bottle, it's like giving the baby a birth control pill."
In his paper, vom Saal says that the latest research showing adverse effects of the chemical are all conducted with an amount of BPA less than the levels normally found in the human body.
"If BPA was treated as a drug, it would have been pulled immediately," vom Saal said. "We are not saying get rid of plastics. This chemical can be replaced right now by safer materials and the public would never notice the difference."
Plastic (Not) Fantastic: Food Containers Leach a Potentially Harmful Chemical

A recent report in the journal Reproductive Toxicology found that humans must be exposed to levels of BPA at least 10 times what the EPA has deemed safe because of the amount of the chemical detected in tissue and blood samples. "If, as some evidence indicates, humans metabolize BPA more rapidly than rodents," wrote study author Laura Vandenberg, a developmental biologist at Tufts University in Boston, "then human daily exposure would have to be even higher to be sufficient to produce the levels observed in human serum."
The CDC data shows that 93 percent of 2,157 people between the ages of six and 85 tested had detectable levels of BPA's by-product in their urine. "Children had higher levels than adolescents and adolescents had higher levels than adults," says endocrinologist Retha Newbold of the U.S. National Institute of Environmental Health Sciences, who found that BPA impairs fertility in female mice. "In animals, BPA can cause permanent effects after very short periods of exposure. It doesn't have to remain in the body to have an effect."

Of the 115 published studies researchers reviewed on the low-dose effects of BPA, 94 of them reported harmful effects on mice and rats; 21 did not.
Coincidentally, none of the 11 studies funded by chemical companies found harmful effects caused by BPA, which the Centers for Disease Control and Prevention has reported is detected in 95 percent of all patients tested.
On the other hand, more than 90 percent of the studies conducted by scientists not associated with the chemical industry [text in blue] discovered negative consequences.

zal er eens achter zoeken. Herhinner me dat ik een tijd geleden er onderzoeken van had en gepost, dus normaal vind ik ze snel terug.
