Owing to their lipophilic properties, the investigations of concentrations and spatial distributions of 16 EPA-PAHs in sediment and soil have been conducted extensively . However, the pollution of PAHs in sediment and soil is a longtime accumulation, and the process is complex, which could reflect the environment pollution degree of a long period of time, but can not reflect the current pollution and sources. Moreover, the soluble PAHs in surface water have direct toxicity to organism.

Based on their lipophilic properties,  concentrations and spatial distributions of 16 EPA-PAHs in sediment and soil have been extensivey investigated. However, as a long-term complex accumulation process, the pollution of PAHs in sediment and soil could not reflect the current pollution and sources, but the environment pollution degree in a long period. Moreover, the soluble PAHs in surface water have direct toxicity to organisms.
