Abstract
The comparative trace mineral profile of bivalve species Lamelliidens corrianus and gastropods species Vivipara bengalensis was monitored in Samaguri beel, a floodplain wetland situated in Nagaon district of Assam. Ca and Mg showed no variation, while K content was almost double in gastropod than bivalve. Cu and Zn were higher in gastropod species than bivalve one, whereas Mn and Cr were higher in bivalve than gastropod. Fe content was comparable in both the species. Cd and Pb were higher in bivalve than gastropod. Higher value of Cu in gastropod and Pb in both bivalve and gastropod with respect to WHO recommended permissible limit indicate that these organisms are unsafe for human consumption.
Key words : Gastropod, bivalve, trace mineral, food safety, wetland
