BPA is used to make plastics and epoxy resins. It can be found in consumer goods, such as water bottles, sports equipment, CDs, and DVDs. BPA is also used in making thermal paper such as that used in cash register and ATM receipts. Between such items, most people in industrialized countries have daily exposure to BPA.

The health effects of exposure to BPA are hotly debated.
The health effects of exposure to BPA are hotly debated. Although many disagree, the U.S. Environmental Protection Agency has declared 50 micrograms per kilogram of body weight per day to be the maximum acceptable dose. While almost everyone who comes in contact with plastics does posses some BPA in their bodies, it is almost always below this level. However, there are conflicting studies, some of which point to there being serious risk from much smaller doses.<ref>"Bisphenol A (BPA)." Britannica Academic. Encyclopædia Britannica, Inc., 2016. Web. 15 Jul. 2016. <http://0-academic.eb.com.www.consuls.org/levels/collegiate/article/598754>.</ref> Another issue is that Bisphenol A is often replaced with Bisphenol S, which although less studied is believed by some to be more dangerous and more easily absorbed than BPA.<ref>http://naturalsociety.com/toxic-bpa-substitute-bps-chemical</ref><ref>http://saferchemicals.org/chemicals/bpa-bps</ref>
