ALTERATIONS IN BIOCHEMICAL CONSTITUENTS DUE TO HEAVY METALS IN BODY TISSUES OF LAMELLIDENS MARGINALLIS FROM GANGAPUR RESERVOIRS AT NASIK, MAHARASHTRA, INDIABALASAHEB RAHANE AND RESHAM BHALLAAbstract The present study investigates the effect of heavy metals Zn, Cu, Pb and Cd on the total proteins,as corbic acid, DNA and RNA content from different soft body tissues of bivalve species,Lamellidensmarginalis collected seasonally (summer, monsoon and winter seasons) from Gangapur reservoir of Nasik district during November 2010 to October 2011. In the present investigation results revealed highest concentrations of heavy metals Zn, Cu, Pb and Cd during summer season in surface water and bivalve species sampled from Gangapur reservoir. The results also revealed the lowest protein, ascorbic acid, DNA and RNA concentrations in different soft body tissues in bivalves sampled during summer season, from Gangapur reservoir might be due to bivalves were exposed to higher concentration of heavy metals in summer than winter and monsoon seasons. |
