The ranges of concentrations of Cd, Cu, Pb and Zn of the soft tissues of C. corteziensis collected in seven coastal lagoons of NW Mexico were 1.55-7.45, 17.50-166.36, 4.13-9.49 and 245.34-2,304.12 microg/g (dry weight), respectively. Their distributions were not consistent and there were no seasonal trends, indicating different point sources of the metals in each lagoon. The mean Cd and Pb concentrations were 5.34 and 6.30 microg/g (dry weight), which are higher than the values indicative of polluted areas. Our data indicate that only the levels of Cd are a possible health risk in six of these lagoons, and only in the case of regular local consumers. In one, Cu and Zn reach levels of concern.
在墨西哥西北部七个沿海泻湖采集的科氏丽体鱼软组织中，镉、铜、铅和锌的浓度范围分别为1.55 - 7.45、17.50 - 166.36、4.13 - 9.49和245.34 - 2304.12微克/克（干重）。它们的分布不一致，且没有季节性趋势，这表明每个泻湖中的金属有不同的点源。镉和铅的平均浓度分别为5.34和6.30微克/克（干重），高于指示污染区域的值。我们的数据表明，在其中六个泻湖中，只有镉的含量可能对健康构成风险，且仅针对当地的经常消费者而言。在一个泻湖中，铜和锌的含量达到了令人担忧的水平。
