Hot topic – A potentially harmful chemical commonly found in certain plastic bottles may be released when those bottles are heated, according to University of Cincinnati scientists. Researcher Scott Belcher and his team found that when the same new and used polycarbonate drinking bottles were exposed to boiling water, an environmental estrogen, BPA, was released 55 times more rapidly than before exposure to hot water.
Previous studies have shown that repeatedly scrubbing or washing certain plastic bottles releases BPA, as well. Belcher says it is still unclear at what level BPA becomes harmful to humans, but urges consumers to consider the cumulative effect of many exposures.
