A new study was conducted by the University of Cincinnati recently that found Bisphenol-A (BPA) can leach into liquids when boiling water was added to polycarbonate containers. The new study revealed it’s the liquids temperature that has the effect.
The Globe and Mail also gives insight as to the extreme effect heat has on bisphenol-a leaching:
Adding boiling water to polycarbonate plastic bottles causes a dramatic spike in the amount of bisphenol A, or BPA, leaching from containers into drinks, according to a U.S. research team.
The finding suggests that parents sterilizing polycarbonate baby bottles by heating them in water or in a microwave may be inadvertently increasing the amount of the estrogen-mimicking chemical leaching from the containers. It also indicates hikers who use the bottles as a thermos to store hot tea or liquids may be doing the same.
The addition of boiling water increased BPA migration rates by up to 55-fold compared with water at room temperature, according to experiments run at the University of Cincinnati. A paper outlining the findings is being released today in Toxicology Letters, a peer-reviewed journal.
