Nature and Formation of PAH and PCB Bound-Residues in the Humin Fraction of Harbor Sediments

摘要

The lipid fraction of harbor sediment organic matter is found to be a significant control on the binding of PAHs. In the absence of lipids, binding is more nonlinear and the binding domain can be characterized as an 'immobile' chemical environment from the PAH's perspective. Additional experiments with authentic polymers raise questions about the applicabilty of dual-mode sorption model to natural organic matter.
