Two species of edible clams Venerupis aurea laeta and Cerastoderma edule glaucum from Ganzirri Lake (Sicily, Italy) were investigated to determine OCP and PCB residues by GC-MS. Thirty-five samples were examined for two years in order to perform: a) their actual contamination; b) the daily dietary exposure of seafood consumers to the pollutants in question. In all the clams analysed in this study, PCB and OCP (4,4'-DDE) residues are always below the limits fixed by law. It seems that there is some seasonality of concentrations observed. In fact the more high concentrations of residues are detected in the hot months, for both species and years. Given the consumption of clams and the values obtained in this study for the two species analysed, it is possible estimate that the average daily dietary intake of NDL-PCB and of 4,4'-DDE for adults is really low.
对来自意大利西西里岛甘齐里湖的两种可食用蛤蜊——金色满月蛤（Venerupis aurea laeta）和青蓝蚶（Cerastoderma edule glaucum）进行了调查，以通过气相色谱 - 质谱联用仪（GC-MS）测定有机氯农药（OCP）和多氯联苯（PCB）残留量。为了进行以下操作，在两年内检测了35个样本：a）它们的实际污染情况；b）海鲜消费者日常饮食中对相关污染物的暴露情况。在本研究分析的所有蛤蜊中，PCB和OCP（4,4'-滴滴伊）残留量始终低于法定限值。似乎观察到了浓度的季节性变化。事实上，在炎热月份，两个物种在两年中均检测到了更高的残留浓度。鉴于蛤蜊的消费量以及本研究中对所分析的两个物种获得的值，可以估计成年人每日饮食中NDL-PCB和4,4'-滴滴伊的平均摄入量确实很低。
