The article focuses on the development of analytical chemistry methods for detecting smaller concentrations of endocrine disrupting chemicals (EDCs) and pharmaceuticals in water. These emerging contaminants appear to be ubiquitous in municipal wastewater treatment plant effluents and in surface waters influenced by effluents, including source waters for drinking water treatment plants. EDCs are agents that interfere with the functioning of natural hormones in the body. Pharmaceuticals found in surface waters include prescription and nonprescription human and veterinary drugs. The U.S. Environmental Protection Agency developed the Endocrine Disruptor Screening Program to identify screening methods and to occur at toxicity testing strategies that can be used to identify chemicals as EDCs. This process is incomplete, and toxicologists have not yet agreed on a testing strategy to definitively determine whether a chemical is an EDC. Many chemicals have not been tested by any method for potential endocrine activity.
