Abstract :
Three estrogens, Bisphenol A(BPA), Dibutyl phthalate(DBP) and Nonylphenol(NP) have been tested for chronic toxicity to algae (Scenedusmus obliquus). The test organisms were exposed at a low concentration of estrogens. The chronic studies were conducted over 15 or 20 days. The results showed that: exposed to low concentration of BPA, DBP and NP, the algal populations were inhibited relative to the control group, and inhibiting effect increased with the increasing concentrations of the test compounds in the chronic studies.
