The accumulation of heavy metals such as lead (Pb), iron (Fe), zinc (Zn), cadmium (Cd), and chromium (Cr) was examined in crab (Scylla serrata) and shrimps (Penaeus semisulcatus, Penaeus indicus, and Penaeus monodon) collected from Pulicat lake that receives effluents from industries located in north Chennai, southeast coast of India. The results showed limited difference between crab and prawns as well as significant variations between the organs. Pb is the highly accumulated metal in both crab and shrimps, except P. monodon. The highest metal concentration was mostly found in the liver followed by other organs. The concentration of metals in edible parts (muscle) was within the permissible level and safe for consumption. However, the results of the study clearly indicate the biomagnification of metals in Pulicat lake.
对从普利卡特湖采集的螃蟹（锯缘青蟹）和虾类（半滑舌对虾、印度对虾和斑节对虾）中铅（Pb）、铁（Fe）、锌（Zn）、镉（Cd）和铬（Cr）等重金属的积累情况进行了检测。该湖接收来自印度东南海岸金奈北部工业区的废水。结果表明，螃蟹和对虾之间差异有限，各器官之间也存在显著差异。除斑节对虾外，铅是螃蟹和对虾中积累量最高的金属。金属浓度最高的部位大多是肝脏，其次是其他器官。可食用部分（肌肉）的金属浓度在允许水平内，食用安全。然而，研究结果清楚地表明了普利卡特湖存在金属生物放大现象。
