Prompted by requests and concern from consumers, University of Cincinnati researchers wanted to see if these alternatives—including products made with stainless steel and coated aluminum—were truly giving the consumer an option free of BPA.

In a study reported in the July 8, 2011 advance online edition of the journal Chemosphere, Scott Belcher, PhD, associate professor in the pharmacology and cell biophysics department, and colleagues found that stainless steel- and/or co-polyester lined-aluminum bottles did not release BPA; however, aluminum bottles lined with epoxy-based resins still resulted in BPA contamination of liquids.

"BPA is an ever-present, high-volume industrial chemical that is an estrogen and an environmental endocrine disrupting chemical,” explains Belcher, adding that it has been shown in experimental models to negatively impact the heart and reproductive system and enhance the growth of certain tumors.
