The Ins and Outs of Estrogen in the Ocean.
Estrogens are hormones produced naturally by humans and other animals and also synthesized for use in pharmaceuticals like birth control pills. Sewage discharges can deliver estrogens to the ocean where even small amounts of excess estrogen may harm marine life. With newfound abilities to detect extremely low levels of estrogens, including chemical forms that previously have escaped notice, scientists have begun to investigate how estrogens enter the ocean and what happens to them there.
