Fate and toxicity of Polycyclic Aromatic Hydrocarbons (PAHs) are influenced by their environmental behaviors and interactions between environmental factors, among which organic matter is the most important factor, affecting physio-chemical behaviors and biological processes of PAHs. This paper reviews current progresses in the research on effects of organic matter on sorption, solubility, transport, bioavailability and toxicity of PAHs in waters, soils and sediments. The paper summarizes that ion intensity, pH, surfactant, and time are the main influencing factors on interaction between organic matter and PAHs and at the same time briefly introduces research on PAHs bound residues in soils and sediments and available methodologies, such as carbon isotope method and pyrolysis method for the research. Sequestration and biodegradation of PAHs in soils in relation to composition and character of native organic matter (especially carbon black and humic acids), and enhanced bioremediation of PAHs contaminated environment with exogenous organic substances should be further studied in the future.
