Surface sediments from the coastal area of the Leizhou Peninsula in the South China Sea were collected and analyzed and the potential ecological risks in the area were assessed based on acid-volatile sulfide (AVS) model. The AVS levels are between 0.109 and 55.6 μmol g(-1), with the average at 4.45 μmol g(-1). The high AVS-concentration zones include the aquaculture areas of Liusha Bay and the densely populated areas of Zhanjiang Bay. The simultaneously extracted metals (SEM) range from 0.026 μmol g(-1) to 8.61 μmol g(-1), with the average at 0.843 μmol g(-1). Most of high SEM-concentration stations were located in ports or aquaculture zones. Most of the coastal surface sediments of the Leizhou Peninsula (90%) had no adverse biological effects according to the criterion proposed by USEPA (2005); while adverse effects were uncertain in some stations (8%); even in 2 stations (2%) adverse biological effects may be expected.
采集了南海雷洲半岛近岸海域的表层沉积物，并基于酸可挥发性硫化物（AVS）模型对该地区的潜在生态风险进行了评估。AVS 含量在 0.109 到 55.6 μmol g(-1) 之间，平均值为 4.45 μmol g(-1)。高 AVS 浓度区包括流沙湾水产养殖区和湛江湾人口稠密区。同时提取的金属（SEM）含量在 0.026 μmol g(-1) 到 8.61 μmol g(-1) 之间，平均值为 0.843 μmol g(-1)。大多数高 SEM 浓度站位位于港口或水产养殖区。根据美国环保署（USEPA）（2005 年）提出的标准，雷洲半岛近岸海域的大部分表层沉积物（90%）没有不良的生物效应；而在一些站位（8%）的生物效应不确定；甚至在 2 个站位（2%）可能会出现不良的生物效应。
