| 摘 要： | 以2015年8月对深圳近岸海域沉积物中PAHs的含量调查资料为基础，采用毒性及致畸性当量和效应区间低、中值法、平均效应区间中值商法等分别进行PAHs的健康风险和生态风险评估。研究表明，深圳近岸海域沉积物中PAHs的含量（干重）范围为（227.51~3897.42）×10-9。PAHs的毒性当量和致畸性当量相对于世界范围内沉积物来说，处于较低的毒性水平和致畸风险状态。深圳湾海域大沙河口附近的表层沉积物对海洋生物可能产生中低毒性，整体生态风险处于中低水平。

| Abstract: | Based on the survey data of marine surface sediments in Shenzhen nearshore in August 2015, this research adopts toxic and mutagenic BaP equivalent、ERL/ERM and MERM-Q method to assess health and ecological risk of PAHs. This study shows that the range of dry weight of PAHs of the sediments in Shenzhen nearshore is (227.51~3897.42)×10-9. Compared with the content in sediment in world, the total toxic and mutagenic BaP equivalent of PAHs is in shape of low toxic level and mutagenic risk status. Also, the sediments in surface around estuary of Dasha river mouth in Shenzhen bay may cause low toxicity, which makes the overall ecological risk be in a low and medium level. |
