We've all heard about the problems with BPA and how it leaches an Estrogen-like chemical. Well it turns out almost all plastics do that though many are unstudied.
The Scary New Evidence on BPA-Free Plastics
And the Big Tobacco-style campaign to bury it.

"(A)lmost 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 (George) Bittner's (professor of neurobiology at the University of Texas-Austin) research, some BPA-free products actually released synthetic estrogens that were more 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 America issued a "consumer alert." The New York Times urged Congress to ban BPA in baby products. Sen. Dianne Feinstein (D-Calif.) warned in the Huffington Post that "millions of infants are exposed to dangerous chemicals hiding in plain view." Concerned parents purged their pantries of plastic containers, and retailers such as Walmart and Babies R Us started pulling bottles and sippy cups from shelves. Bills banning BPA in infant care items began to crop up in states around the country.
Today many plastic products, from sippy cups and blenders to Tupperware containers, are marketed as BPA-free. But Bittner's findings—some of which have been confirmed by other scientists—suggest that many of these alternatives share the qualities that make BPA so potentially harmful.
