This technical note 1 relates the importance of the toxicological exposure potential of hydrophobic organic contaminants HOC in sediments and dredged material to implementation of public laws and regulations governing environmental risk assessment, 2 summarizes recent peer-reviewed literature on sediment HOC exposure potential in the context of the sorbant quality of sediment organic carbon and microbial degradation, and 3 introduces the practical utility of thermal desorption mass spectrometry with respect to identification and quantification of HOC, measuring HOC release energy, and the compatibility of the development of field-portable direct sampling analytical technologies.
