title: Assessing PAHs pollution in Qingdao coastal area (China) by the combination of chemical and biochemical responses in scallops, Chlamys farreri.
abstract: The PAHs concentrations in seawater and tissues from the scallop Chlamys farreri were detected in three sites in Qingdao, China in 2011. The PAHs concentrations in seawater ranged from 25.32 ng/L to 314.62 ng/L. There were significant differences (p<0.05) between the residual levels among scallop tissues. The highest concentrations of PAHs in seawater and tissues were found in S2. The ethoxyresorufin-O-deethylase (EROD) activity of the digestive gland and the malondialdehyde (MDA) contents of the digestive gland and gill were sensitive to PAHs (p<0.05). This study integrated the PAHs concentrations in seawater, residual levels, the variation of biochemical response and the correlation coefficient analysis, and concluded that Qingdao is a medium PAH-contaminated area on a global scale. The highest PAHs were accumulated in the digestive gland followed by the gill, soft tissue and adductor muscle. The EROD activity of the digestive gland and the MDA contents of the digestive gland and gill could be applied to assess the PAHs pollution status in Qingdao, China.
