Arsenic, cadmium, copper, lead, and zinc concentrations in the edible part of wild and farmed Sparus aurata from Algerian coastal were determined. The highest concentrations of cadmium (0.0078 mg kg wet weight), copper (0.98 mg kg w.w), and zinc (5.1 mg kg w.w) were recorded in farmed sea bream, whereas the highest arsenic (5.02 mg kg w.w) and lead (0.006 mg kg w.w) levels were registered in wild one. The statistical analysis (Friedman test, p < 0.05) indicated that the origin of fish (wild, farmed in a cage, and farmed in raceway) has relevance to the distribution of metal. Estimated weekly intake of inorganic arsenic, cadmium, and lead for a 72.5-kg person consuming Sparus aurata from Algeria does not exceed 1% of the WHO/JECFA recommended rate for all metals, certainly due to the limited consumption of seafood products by the local population. The total target hazard index is far less than "one" 1, and the carcinogenic risk for arsenic exceeds the acceptable value of 10. Based on the result of this study, the potential risk to human health from the consumption of contaminate farmed sea bream (in the cage) should be considered.
测定了阿尔及利亚沿海野生和养殖 Sparus aurata 可食用部分的砷、镉、铜、铅和锌浓度。养殖的海鲷体内镉（0.0078 毫克/千克湿重）、铜（0.98 毫克/千克湿重）和锌（5.1 毫克/千克湿重）的浓度最高，而野生海鲷体内砷（5.02 毫克/千克湿重）和铅（0.006 毫克/千克湿重）的浓度最高。统计分析（弗里德曼检验，p<0.05）表明，鱼类的来源（野生、网箱养殖和流水养殖）与金属的分布有关。对于一个 72.5 公斤的人来说，每周摄入无机砷、镉和铅的量来自食用阿尔及利亚 Sparus aurata 的量不超过世界卫生组织/粮农组织联合专家委员会对所有金属推荐摄入量的 1%，这肯定是由于当地人口对海鲜产品的消费有限。总的目标危害指数远小于“一”1，而且砷的致癌风险超过了 10 的可接受值。基于这项研究的结果，应该考虑食用受污染的养殖海鲷（在网箱中）对人类健康的潜在风险。
