Sediment was collected from Suzhou Creek in Shanghai, China. Wet-sieved through 1-mm mesh and
homogenized by physical mixing, the sediment’s basic properties are described in Table 1. The total
carbon and nitrogen is 1.4 and 0.2%. The content of phenanthrene (PHE) and anthracene (ANT) is 0.713
and 0.287 mg/kg respectively. These PAH levels were less than the limitation of sediment Quality
guideline (SQGs) (U.S. Environmental Protection Agency 1997). Therefore, the doped sediment was used
in this study.
