This book surveys current knowledge regarding endocrine disruptors and other hormone-mimicking compounds in the environment as a result of the disposal of cosmetics, drugs, and cleaning agents. The book investigates dozens of biologically active pollutants, describes their physiological effects, and assesses the evidence of their impact on humans and wildlife. Substances treated include phthalates, bisphenol-A, hormones and an array of steroids. Techniques being investigated by the EPA for the detection and analysis of steroids and hormones in water samples are presented. This is a key reference volume for environmental health, risk assessment and water/wastewater technology.
