Toxicological Exposure of Sediment-Bound Hydrophobic Organic Contaminants as a Function of the Quality of Sediment Organic Carbon and Microbial Degradation.

摘要

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.
