health Studying drugs in wastewater. Researchers at the National Institute of Standards and Technology (NIST) have published an interesting study that sheds light on the fate of a familiar pharmaceutical as it enters the waste stream. In work initially described last year, NIST chemists investigated probable chemical reactions involving acetaminophen when the drug is subjected to typical wastewater processing. Acetaminophen is the most widely used pain reliever in the United States, and a study of 139 streams by the U.S. Geological Survey found that it was one of the most frequently detected man-made chemicals.
