The concentrations of metals, Cd, Cu, Fe, Mn, Ni, Pb, and Zn were determined in some lagoons to establish the level of metal pollution. The lagoons studied were Alvarado lagoon, Veracruz; San Andres lagoon, Tamaulipas; and Terminos lagoon, Campeche. The concentrations were determined in water, oyster (Crassostrea virginica), and sediments. Metals were accumulated in either oysters or sediments. Cu and Zn were higher in oysters and Fe and Mn were higher in sediments. The results in water samples were compared with the limit established by the Secretaria de Ecologia and Desarrollo Urbano Report and briefly discussed.
为确定金属污染水平，对一些泻湖中的镉（Cd）、铜（Cu）、铁（Fe）、锰（Mn）、镍（Ni）、铅（Pb）和锌（Zn）的浓度进行了测定。所研究的泻湖有韦拉克鲁斯州的阿尔瓦拉多泻湖、塔毛利帕斯州的圣安德烈斯泻湖以及坎佩切州的特尔米诺斯泻湖。对水、牡蛎（美洲牡蛎）和沉积物中的浓度进行了测定。金属在牡蛎或沉积物中蓄积。牡蛎中的铜和锌含量较高，沉积物中的铁和锰含量较高。将水样的结果与生态与城市发展秘书处报告规定的限值进行了比较并作了简要讨论。
