|In an unusual effort targeting a single chemical, several dozen scientists on Thursday issued a strongly worded consensus statement warning that an estrogen-like compound in plastic is likely causing an array of serious reproductive disorders in people.|
The compound, bisphenol A or BPA, is one of the highest-volume chemicals in the world and has found its way into the bodies of most human beings.
Used to make hard plastic, BPA can seep from beverage containers and other materials. It is used in all polycarbonate plastic baby bottles as well as other items, including large water cooler containers, sports bottles and microwave oven dishes, along with canned food liners and some dental sealants for children.
The scientists — including four from federal health agencies — reviewed about 700 studies before concluding that people are exposed to levels of the chemical exceeding those that harm lab animals. Infants and fetuses are most vulnerable, they said.
The statement, published online by the journal Reproductive Toxicology, was accompanied by a new study from researchers from the National Institutes of Health that found uterine damage in newborn animals exposed to BPA. That damage is a possible predictor of reproductive diseases in women, including fibroids, endometriosis, cystic ovaries and cancers.
It is the first time BPA has been linked to disorders of the female reproductive tract, although earlier studies have found early-stage prostate and breast cancer and decreased sperm counts in animals exposed to low doses.
The scientists' statement and the new study — accompanied by five scientific reviews summarizing the 700 studies — intensify a contentious debate over whether the plastic compound poses a public threat. So far no government agency here or abroad has restricted its use.
