Marine edible fish samples were collected from two important nearshore fishing sites in the eastern Guangdong Province, China: Shantou Harbor and Haimen Bay. In the mixed edible muscle tissues of marine fish samples, the concentrations of polychlorinated biphenyls, dichlorodiphenyltrichloroethanes (DDTs), hexachlorocyclohexanes (HCHs), chlordanes, and hexachlorobenzene ranged from 1.12 to 53.87, ND (not detected) to 84.01, 0.22 to 7.09, ND to 4.74, and ND to 1.49 ng/g wet weight (ww) in Haimen Bay, respectively, and from ND to 70.35, ND to 164.83, ND to 8.68, ND to 25.61, and ND to 1.76 ng/g ww in Shantou Harbor, respectively. The concentrations of PCBs, DDTs, and HCHs in all samples did not exceed maximum residue limits (China and United States Food and Drug Administration). However, a few fish samples exceed the maximum levels established by the European Union. Daily fish consumption from this region can be of serious concern, and lifetime cancer risk remains a possibility in the studied area.
汕头港和海门湾，采集了海洋食用鱼类样本。在海洋鱼类样本的混合可食肌肉组织中，多氯联苯、滴滴涕（DDT）、六氯环己烷（HCHs）、氯丹和六氯苯的浓度范围分别为海门湾 1.12 至 53.87、未检出（ND）至 84.01、0.22 至 7.09、ND 至 4.74 和 ND 至 1.49ng/g 湿重（ww），而在汕头港则分别为 ND 至 70.35、ND 至 164.83、ND 至 8.68、ND 至 25.61 和 ND 至 1.76ng/g ww。所有样本中的多氯联苯、滴滴涕和六氯环己烷浓度均未超过最大残留限量（中国和美国食品药品监督管理局）。然而，一些鱼类样本超过了欧盟设定的最高限量。该地区的鱼类日摄入量可能令人严重关切，并且在研究区域终生患癌症的风险仍然存在。
