Bisphenol A, also known as BPA, is a ubiquitous environmental toxicant. BPA is a polymerizing agent that is commonly found in items such as plastics, store receipts, dental adhesive, and lining of beverage and food cans.3 Six billion pounds per year are produced worldwide, which is prevalent in aquatic life as well.4 The Environmental Protection Agency was granted the authority to require testing, reporting and restrictions for manufacturing companies by Congress when the Toxic Substance Act was passed in 1976. Since this, science and the law has been working together to safeguard the public from the negative effects due to chemical exposures. The Agency for Toxic Substance and Disease Registry (ATSDR) was formed by congress as part of the Comprehensive Environmental response in 1980. The ATSDR is a public health agency, that is based off of scientific studies of these dangerous chemical substances and the effects they have on health. Several communities are worked with in conjunction to the ATSDR in order to keep them out of harm’s way. In the studies conducted the data collected showed essential information about the health effects BPA has. In 2014, there was a Children’s Health Exposure Analysis Resource (CHEAR) that allowed the effects the environment has on children’s health to be observed.2 The EPA has provided information of immediate exposure to toxicants and their enduring health effects to human health through model organisms. BPA is dangerous because when exposed to extreme environments (i.e. Heat, acidic or basic), the ester bond links in BPA go through hydrolysis which enables a monomer to be released.3 BPA has structural and functional resemblance to estrogen (Fig. 1), specifically 17 beta estradiol (E2) as well as, alpha and beta estrogen receptors.7 Due to the resemblance, it has shown to affect the reproductive system in both sexes disrupting gene expression in embryos as well as endocrine pathways, semen quality, and fecundity/infertility. Effects of BPA’s presence can be seen through low dose exposure, when there is high exposure the reactions are inhibited therefore no response is seen.3 Due to the increase in exposure we have of BPA, there has been in infertility. Many studies have been trying to prove what exactly does our environment have to deal with fecundity. Exposure to BPA is so common that it is impossible to not be affected by it. Mice, sea urchin, nematodes, zebrafish, and even humans have had numerous case-studie>GET ANSWER
