Mussels, Perna viridis L., obtained from three selected seafood markets in Metro Manila, were tested for metal content including cadmium, copper, lead, and zinc through atomic absorption spectrophotometry. Water samples from Bacoor Bay, Cavite, which supplies mussels to the market, were likewise subjected to similar metal analyses. Of the metals analyzed in the soft tissues of mussels, only copper and lead with highest obtained values of 10.4 mg/kg and 2.3 mg/kg, respectively exceeded the PEMSEA guideline for safe human consumption. Water samples collected from the harvest sites in Bacoor Bay showed high concentrations of cadmium (0.023 mg/L) and lead (0.25 mg/L) that exceeded the standards of DENR, ASEAN, and US EPA. Zinc, though detected in relatively high concentrations in both water (0.03 mg/L) and soft tissues (12.16-14.43 mg/kg) of mussels remained below the criteria set by the above-mentioned agencies. Overall, the present study indicates that mussels being sold in selected Metro Manila seafood markets were contaminated with metals, notably Cu and Pb, at concentrations that are unsafe for human consumption and thus, represents a health risk.
从马尼拉三个选定的海鲜市场中获取的贻贝（Perna viridis L.），通过原子吸收分光光度法进行了包括镉、铜、铅和锌在内的金属含量测试。同样对供应贻贝的巴科奥湾（Bacoor Bay）的水样进行了类似的金属分析。在所分析的贻贝软组织中的金属中，只有铜和铅的含量最高，分别为 10.4 毫克/千克和 2.3 毫克/千克，超过了 PEMSEA 安全人类食用指南的标准。从巴科奥湾（Bacoor Bay）收获点采集的水样显示，镉（0.023 毫克/升）和铅（0.25 毫克/升）的浓度很高，超过了 DENR、东盟和美国环保署的标准。锌虽然在贻贝的水（0.03 毫克/升）和软组织（12.16-14.43 毫克/千克）中均以相对较高的浓度检测到，但仍低于上述机构设定的标准。总体而言，本研究表明，在马尼拉选定的海鲜市场出售的贻贝受到金属污染，特别是铜和铅，其浓度对人类食用不安全，因此构成健康风险。
