ABSTRACT For nonpolar chemicals generally have the potential acute and long-term effects on marine environments, a resurgence of investigations of the fate, transport and chemical transformations in marine environment has come out. Sorption is an important parameter for assessing the fate, transport and toxicological impact of pollutants such as dimethyl phthalate, diethyl phthalate, chlorobenzene, nitrobenzene, benzothiophene and dibenzothiophene. These nonpolar chemicals’ sorption behaviors on marine sediments had been carefully investigated in our laboratory. The article aimed to detailedly summarize these recent studies and an emphasis was made on the relationship between the solubility of the nonpolar compounds (or octanol-water partitioning coefficient (Kow)) and their Koc values. According to the summarization, two empirical equations found in our studies were presented. Furthermore, the influence of aqueous salinity on sorption of nonpolar organic compounds was discussed in detail.
