Chemicals of emerging concern in water and bottom sediment in Great Lakes areas of concern, 2010 to 2011-Collection methods, analyses methods, quality assurance, and data

Abstract

Synoptic surveys of surface-water quality across the United States have detected a large group of organic chemicals associated with agricultural, household, and industrial waste. These chemicals are referred to collectively as chemicals of emerging concern (CECs) and include, for example, prescription drugs and antibiotics, over-the-counter medications, reproductive hormones, personal-care products, detergent metabolites, and flame retardants.
