Mother Jones: Do BPA-Free Plastics ALSO contain synthetic hormones?

I’ve switched to glass for my leftovers… but my pre-made TJ salads come in plastic… this is a HUGE problem…

MOTHER JONES:  To help solve the riddle, he said, his organization planned to test BPA-free sippy cups for estrogenlike chemicals.

The center shipped Juliette’s plastic cup, along with 17 others purchased from Target, Walmart, and Babies R Us, to CertiChem, a lab in Austin, Texas. More than a quarter—including Juliette’s—came back positive for estrogenic activity. These results mirrored the lab’s findings in its broader National Institutes of Health-funded research on BPA-free plastics. CertiChem and its founder, George Bittner, who is also a professor of neurobiology at the University of Texas-Austin, hadrecently coauthored a paper in the NIH journal Environmental Health Perspectives.It reported that “almost all” commercially available plastics that were tested leached synthetic estrogens—even when they weren’t exposed to conditions known to unlock potentially harmful chemicals, such as the heat of a microwave, the steam of a dishwasher, or the sun’s ultraviolet rays. According to Bittner’s research, some BPA-free products actually released synthetic estrogens that weremore potent than BPA.

Estrogen plays a key role in everything from bone growth to ovulation to heart function. Too much or too little, particularly in utero or during early childhood, can alter brain and organ development, leading to disease later in life. Elevated estrogen levels generally increase a woman’s risk of breast cancer.

Estrogenic chemicals found in many common products have been linked to a litany of problems in humans and animals. According to one study, the pesticide atrazine can turn male frogs female. DES, which was once prescribed to prevent miscarriages, caused obesity, rare vaginal tumors, infertility, and testicular growths among those exposed in utero. Scientists have tied BPA to ailments including asthma, cancer, infertility, low sperm count, genital deformity, heart disease, liver problems, and ADHD. “Pick a disease, literally pick a disease,” says Frederick vom Saal, a biology professor at the University of Missouri-Columbia who studies BPA.

BPA exploded into the headlines in 2008, when stories about “toxic baby bottles” and “poison” packaging became ubiquitous. Good Morning Americaissued a “consumer alert.” The New York Times urged Congress to ban BPA in baby products.
