Bisphenol A Environmental Safety
Bisphenol A (BPA) is an important industrial chemical that is used primarily to make polycarbonate plastic and epoxy resins, both of which are used in a wide variety of applications. Although the vast majority of bisphenol A is converted at manufacturing sites into products, low- level releases of BPA to the environment are possible. Numerous validated studies have been completed to determine what happens to BPA in the environment ("environmental fate") and the possible impacts ("environmental assessment"). Recent comprehensive reviews of these studies, combined with current scientific understanding of BPA toxicity, conclude that current manufacturing and use patterns of BPA pose virtually no risk to the environment.
While low levels (less than 0.1%) of the BPA used at manufacturing sites may be released into the environment through dust or other means, laboratory tests have proven that breakdown of BPA through biodegradation is rapid and extensive. The standard biodegradation tests of the Organization for Economic Cooperation and Development (OECD) classifies bisphenol A as readily biodegradable. Moreover, tests have shown that BPA does not accumulate in aquatic organisms and is not classified as bioaccumulative by the U.S. Environmental Protection Agency. Therefore, the small amount of bisphenol A that does escape degrades quickly and is not harmful to the environment or to humans.
