Analysis and environmental levels of endocrine-disrupting compounds in freshwater sediments

An overview of analytical methods for target endocrine-disrupting compounds (EDCs) in freshwater sediments is presented. Among the EDCs we have selected five groups of compounds that are of priority within European Union and USA research activities: alkylphenols, polychlorinated compounds (dioxins, furans and biphenyls), polybrominated diphenyl ethers, phthalates and steroid sex hormones. Various aspects of current analytical methodology, such as sample preparation, extraction, purification and final determination, are discussed. Levels found in freshwater sediment are reviewed.
