The present investigation was carried out from April 2002 to January 2003 in respect of pre-monsoon, monsoon and post monsoon periods to evaluate the Seasonal variation of Heavy Metals in water of Shitalakkhya river. Seasonal variation of heavy metals such as Copper (Cu), Lead (Pb), Cadmium (Cd), Calcium (Ca),Magnesium(Mg), Zinc(Zn), Manganese(Mn) and Iron(Fe) concentrations in water and sediments. By employing air-acetylene and Nitrous Oxide flame in combination with single element hollow cathodes lamps and atomic absorption spectrophotometer (GBC-902). In water, metal concentrations ( were found to range from 0.00 to 0.003 for Cu, 0.0027 to 0.0056 for Pb, 0.0010 to 0.009 for Cd, 8.0 to 16.3 for Ca, 5.8 to 15.5 for Mg, 3.91 to 10.87 for Zn, 3.00 to 9.24 for Mn and 4.00 to 21.92 for Fe.
