ABSTRACT - This study investigated factors affecting assimilation of naphthalene in two wetland substrates: a mineral-dominated wetland soil and organic matter-dominated wetland soil. Assimilation of naphthalene in two wetland system was enhanced by rapid mineralization rate, sorption on wetland soil and diffusive exchange between the overlying water column and bed. Degradation appeared to be dependent on the presence of aerobic conditions in the wetland soil. High concentration of dissolved organic carbon(DOC) in the organic matter-dominated wetland soil decreased sorption. Large differences in the DOC concentrations for the aerobic and anaerobic suspension suggest a role for this phase in the sorption of naphthalene. These results indicate that several processes affect the assimilation of organic contaminants in wetlands, including biodegradation, sorption, and sediment-water exchange.
