A study was conducted using adult female Gobiocypris rarus, a rare minnow. The fish were exposed to 5 μg/L, 15μg/L and 50 μg/L of BPA for 14 days and 35 days. [117] The results showed the group exposed to the highest amount of BPA (50 μg/L) for 35 days showed suppressed effects on oocyte development. [117]
BPA has been found to interact with a diverse range of hormone receptors, in both humans and animals. [78] It binds to both of the nuclear estrogen receptors (ERs), ERα and ERβ. BPA is a selective estrogen receptor modulator (SERM), or partial agonist of the ER, so it can serve as both an estrogen agonist and antagonist.
Studies have shown that at temperatures above 70 °C, and high humidity, polycarbonate will hydrolyze to bisphenol A (BPA). After about 30 days at 85 °C/96% RH, surface crystals are formed which for 70% consisted of BPA. [34] BPA is a compound that is currently on the list of potential environmental hazardous chemicals.

Allergic reaction sometimes occurs at a time which is delayed several days from the exposure. Allergic reaction is often visible in the form of dermatitis, particularly in areas where the exposure has been highest (commonly hands and forearms). Epoxy use is a main source of occupational asthma among users of plastics. [74]
