七种目标多氯联苯（PCBs; IUPAC nos. 28、52、101、118、138、153和180）以及有机氯农药（OCPs）六氯苯（HCB）和二氯二苯基三氯乙烷（DDT）及其相关代谢物对7种海洋生物的可食组织中的DDT、p，p '-DDE和pp'-DDD进行了定量分析产于第勒尼安海南部那不勒斯湾（意大利）的欧洲无须鳕、红鲻鱼、蓝鳕鱼、大西洋鲭鱼、蓝虾和红虾、欧洲飞乌贼和地中海贻贝。PCBs 118、138和153是所检查的所有物种中的主要同族体。在分析的样本中，所有多氯联苯的浓度（从无法检测到15，427纳克/克脂肪重量）超过了所有滴滴涕（从无法检测到1，769纳克/克脂肪重量）和六氯苯（无法检测到150.60纳克/克脂肪重量）。在分析的所有样品中，OCP浓度均低于2005年5月13日部长法令为鱼类和水产品规定的最大残留限量;因此，第勒尼安海南部物种中的OCP不太可能对健康造成重大危害。相反，多氯联苯的平均浓度超过了（在某些情况下大大超过了）欧洲联盟为陆地食物设定的现行限值（200纳克（-1）脂肪重量）。虽然多氯联苯的生产和使用被禁止或受到严格限制，但这些化合物仍然是那不勒斯湾重要的持久性化学污染物。
Seven target polychlorinated bipheryls (PCBs; IUPAC nos. 28, 52, 101, 118, 138, 153, and 180) and the organochlorine pesticides (OCPs) hexachlorobenzene (HCB) and dichlorodiphenyltrichloroethane (DDT) and its related metabolites (pp'-DDT, p,p'-DDE, and pp'-DDD) were quantified in edible tissues from seven marine species (European hake, red mullet, blue whiting, Atlantic mackerel, blue and red shrimp, European flying squid, and Mediterranean mussel) from the Gulf of Naples in the southern Tyrrhenian Sea (Italy). PCBs 118, 138, and 153 were the dominant congeners in all the species examined. The concentrations of all PCBs (from not detectable to 15,427 ng g(-1) fat weight) exceeded those of all the DDTs (from not detectable to 1,769 ng g(-1) fat weight) and HCB (not detectable to 150.60 ng g(-1) fat weight) in the samples analyzed. The OCP concentrations were below the maximum residue limits established for fish and aquatic products by the Decreto Ministerale 13 May 2005 in all the samples analyzed; therefore the OCPs in the southern Tyrrhenian Sea species are unlikely to be a significant health hazard. Conversely, the mean concentrations of PCBs exceeded (greatly in some cases) the current limits (200 ng(-1) fat weight) set by the European Union for terrestrial foods. Although the manufacture and use of PCBs are banned or highly restricted, these compounds still are important persistent chemical contaminants in the Gulf of Naples.
