WebThe ISQGs and PELs refer to total concentrations of PAHs in the surficial sediment (i.e., top 5 cm), as quantified by extraction and determination by recognized analytical procedures for PAHs. Currently, there is sufficient scientific information to develop ISQGs for 13 PAHs in marine sediments and 6 PAHs in freshwater sediments. http://st-ts.ccme.ca.vsd46.korax.net/?chems=all&chapters=all global business network peter schwartz
