Scientists have spotted a steep decline in the levels of toxic flame-retardant chemicals.
Researchers at the San Francisco Estuary Institute were pleased to recently announce [PDF] that levels of PBDE (polybrominated diphenyl ethers) have declined dramatically since a state-enacted ban.
PBDEs have been shown to bioaccumulate and be toxic both to humans and wildlife. More on PBDEs from the U.S. Environmental Protection Agency.
