Addition of Carbonaceous Material to Aquatic Sediments for Sorption of Lindane and <i>p,p</i>’-Dichlorodiphenyldichloroethylene

Isomers of hexachlorocyclohexanes (HCHs) and metabolites of dichlorodiphenyltrichloroethanes (DDTs) are still frequently detected worldwide in considerable amounts, even decades after their prohibition. Carbonaceous materials (CMs) have been shown to significantly reduce risks of propagation to huma...
