Human intake of persistent organic pollutants (POPs) occurs primarily through diet and fish and other seafood represent the principal means of contamination. Despite this, few legal limits have been established to protect human health from the various chemicals that are alleged to be carcinogenic or endocrine disruptor compounds. Several pools of edible clams (Tapes philippinarum and Venus gallina) bought in different Italian and European markets were examined in order to perform a risk assessment of some of these contaminants and also to identify possible health issues. POP concentrations in the soft tissues of mollusks varied considerably among source farming sites, particularly in the Venice Lagoon. Some POPs (DDTs, HCB and HCHs) showed very low concentrations and no risk for human health, in line with the limits established by European law. In contrast, PAHs could represent a potential hazard for human health and PCB levels in the most contaminated sites reached or even exceed the Minimal Risk Level as set by the ATSDR for human consumption, even if all the samples did not exceed the PCB limits in edible seafood as set by the FDA.
人类对持久性有机污染物（POPs）的摄入主要通过饮食，鱼类和其他海产品是主要的污染途径。尽管如此，为保护人类健康免受各种据称具有致癌性或内分泌干扰作用的化学物质影响而制定的法律限制却很少。为了对其中一些污染物进行风险评估并确定可能的健康问题，对在不同意大利和欧洲市场购买的几批食用蛤（菲律宾蛤仔和光滑河蓝蛤）进行了检测。软体动物软组织中的持久性有机污染物浓度在不同的养殖产地差异很大，特别是在威尼斯泻湖。一些持久性有机污染物（滴滴涕、六氯苯和六氯环己烷）浓度很低，对人类健康没有风险，符合欧洲法律规定的限值。相比之下，多环芳烃可能对人类健康构成潜在危害，在污染最严重的地区，多氯联苯水平达到甚至超过了美国有毒物质和疾病登记署（ATSDR）规定的人类消费最低风险水平，尽管所有样本均未超过美国食品药品监督管理局（FDA）规定的可食用海产品中多氯联苯的限值。
