520 | |a"The occurrence of estrogenic compounds in the environment has created concern lately since they have the potential to interfere with the reproductive systems of fish, wildlife, and humans. Among these endocrine disruptors, the most potent ones include the naturally occurring 17ß-estradiol and the synthetic 17α-ethynylestradiol which is used as an oral contraceptive for women. The presence of these estrogens at ng/L concentrations in sewage treatment plant effluents has been reported. This report describes new analytical methods for the detection of estrogens at trace levels"--Management perspective. |
