Shanti K., Kasthuri H., Ramasamy K., and Lakshmanaperumalsamy P.


The present paper deals with the accumulation of heavy metals (copper, zinc, cadmium, iron, lead and nickel) in different organs (gills, intestine and muscle) of the fish species (Sarothredon mossambica, Cyprinus carpio and Catla catla) of Singanallur lake was determined by Atomic Absorption Spectrophotometer. The study was conducted for a year (January 2000 to December 2000). The trend in accumulation of heavy metals indicated that irrespective of the species zinc, lead and iron showed higher concentration as compared to other metals. Higher concentration of metals was recorded in the intestine as compared to other parts of the body i.e., gills and muscles.
