METAL EXPOSURE TO FRESHWATER BIVALVE MOLLUSCS LAMELLIDENS MARGINALIS FROM KUTLUQ LAKE OF DUALTADABAD DISTRICT AURANGABAD (M. S.) INDIA, IN RELATION TO ASCORBIC ACID CHANGES DURING SUMMER SEASON

Abstract

The present study was conducted to determine alterations in ascorbic acid contents after 96hrs acute toxicity of cadmium in different body parts viz. mantle, gill, gonad, hepatopancreas, siphon, foot, anterior adductor muscle and posterior adductor muscle of freshwater bivalve in Lamellidens marginalis in summer season in respective groups i.e. control Lc0 and Lc50 groups. In control group the content was high from posterior adductor muscle (1.897±0.036). In Lc0 group when compared to control group the content was high from gonad (209.25% p< 0.001). In Lc50 group content was high from gonad (138.43% p< 0.001) when it was compared to control group. On the other hand when compared to Lc0 group show significantly increased from gill (41.75% p< 0.001).
