The edible fishes Etroplus suratensis and Arius arius were collected from two different sites of Vembanad backwaters. Accumulation of heavy metals such as zinc, cadmium, lead and copper in different tissues of these fishes were analysed. Kidneys showed maximum accumulation of all the metals in both the fishes. Lead and copper were high in Kumarakom (Site-I) and zinc and cadmium in Cochin (Site-2) of the Vembanad backwaters. The study revealed that both the fishes were highly contaminated with metals.
食用鱼苏拉特无须鲃和长丝鮠是从汶班纳德回水区的两个不同地点采集的。分析了这些鱼不同组织中锌、镉、铅和铜等重金属的积累情况。肾脏在两种鱼的所有金属积累中都显示出最大值。在汶班纳德回水区的库马拉孔（地点一），铅和铜含量较高，而在科钦（地点二），锌和镉含量较高。研究表明，这两种鱼都受到了金属的高度污染。
