Abstract

The aim of the study was to determinate the level of lead, cadmium and mercury on the edible part of Peruvian scallop ( Argopecten purpuratus Lamarck , 1819) and mussel ( Aulacomya ater Molina, 1782) from 2009 to 2012 in the major production areas of Peru and to compare the results with the maximum levels set by the European Union (EU) and consequently evaluate any health risks for consumers. Peruvian scallop samples from suspended culture were extracted from growing areas of Sechura, Samanco and Paracas. Mussel samples were extracted from natural banks from Marcona and Atico. THQ (target hazard quontient) values for Pb, Cd, Hg in Peruvian scallops, plus Pb and Hg in mussels were less than 1 (even less than 0.25), unlike Cd in mussels from Marcona and Atico which exceeded the maximum level allowed and presented THQ values greater than 1, representing a possible health risk. A maximum weekly consumption rate was estimated.
秘鲁商业物种紫锥眼镜鱼(LAMARCK,1819)和水Aulacomya(Molina,1782)中铅、镉和汞的生物累积和风险评估
本研究的目的是测定2009年至2012年秘鲁主要产区秘鲁扇贝(Argopecten purpuratus Lamarck,1819)和贻贝(Aulacomya ater Molina,1782)可食用部分的铅、镉和汞含量,并将结果与欧盟设定的最高水平进行比较,从而评估消费者的任何健康风险。从Sechura、Samanco和Paracas的生长区提取了悬浮培养的秘鲁扇贝样本。贻贝样本是从马科纳和阿提科的天然河岸提取的。秘鲁扇贝中Pb、Cd、Hg以及贻贝中Pb和Hg的THQ(目标危害量)值小于1(甚至小于0.25),而Marcona和Atico贻贝中的Cd超过了允许的最大水平,THQ值大于1,这代表了可能的健康风险。估计了每周的最高消费率。
