The California state Senate voted Tuesday to ban bisphenol A, also known as BPA, from baby bottles and sippy cups sold statewide.
The Toxin-Free Infants and Toddlers Act heads back to the state Assembly for a vote on Senate amendments later this year.
"Today's action by the Senate is further proof that the interests of California's children can have a voice in Sacramento," said Renee Sharp, head of the nonprofit Environmental Working Group's California office.
Martha Dina Argüello, executive director of Physicians for Social Responsibility-Los Angeles, said Tuesday's vote "is part of reasserting California's leadership on environmental health protections."
