Some Aluminum Water Bottles Leach BPA
Study: Bottles That Claim to Be BPA-Free Largely Live Up to Their Promises
BPA in Aluminum Bottles continued...
“For the consumer, this is a tricky issue, to try to boil this down to some simple, useful tips that people can use to distinguish products,” Lunder says. “This study is kind of showing that you can’t just look at what’s outside of the container, you need to know some specifics about what’s on the inside.”
One thing people can do to reduce their exposure, Lunder says, is to carefully follow the manufacturer’s directions about how to use the bottles.
The study found that epoxy-lined bottles released even more BPA when the water was heated before it was poured in.
BPA-Free Claims May Hold Water
The good news is that some companies that make reusable water bottles have already listened to consumer concerns about BPA and removed it from a newer generation of materials for their containers.
Those bottles, which say "BPA-Free" on the packaging, largely live up to their promises, the study showed.
Two containers, an aluminum bottle with a newer kind of proprietary liner and a next-generation plastic bottle, both had low-to-undetectable BPA levels in the test.
That’s an important finding, researchers point out, because “BPA-free” really doesn’t have any regulatory meaning or definition. Consumers are left to trust companies about their claims.
The study also exonerated uncoated stainless steel bottles.
Experts say the new study should serve as a wake-up call to consumers and government regulators.
“This new study finds that some products marketed as BPA-free alternatives are -- and some are not -- BPA free, reinforcing that we have a buyer-beware consumer economy with very little government oversight,” says Ruthann Rudel, director of research at the Silent Spring Institute in Newton, Mass., in an email to WebMD.
“People want to know that their health is not jeopardized by food packaging and other consumer products, and to get there we need to rethink our approach to chemical regulation,” she says.
