Abstract

The soft vs. hard soil/sediment organic matter (SOM) components were compared. The sorption behavior for each SOM component and its contribution to the overall sorption by a soil or sediment was characterized. Phenanthrene and naphthalene sorption isotherms were measured for the sandy soil series samples. Humic acid was a minor sorbent and kerogen and black carbon (BC) were the major components for the sorption of phenanthrene and naphthalene by the tested soils and sediments. The isolated kerogen and BC had much higher sorption capacity than when they are associated with soils and sediments. Large fractions of surfaces and matrices of SOM in soils and sediments were not accessible to sorbing molecules.
