The persistence of steroidal estrogens in the aquatic environment

Susanna Kate Atkinson
The presence and fate of the steroidal estrogens, estrone (E1), 17beta-estradiol (E2) and 17alpha-ethinylestradiol (EE2), in Ottawa and Cornwall wastewater treatment plants (WWTP's), drinking water, and the river water used as the drinking water source, were identified. Estrogens were extracted using accelerated solvent extraction, gel permeation chromatography and solid phase extraction, and identified using gas chromatography-mass spectrometry and internal C-13 standards. E1, E2 and EE2 concentrations ranged from 1.8 to 370, 24.3 to 66.9 and...
