Abstract :

The salts of heavy metal, released from commercial, industrial sources passes into aquatic ecosystem. Heavy metals are most hazardous pollutants because of their non–degradable nature. The heavy metals enter into body of aquatic animals and reaches up to non–target animal i.e. man through the food chain. Glycogen content of animal changes indicate the stress in pollutant exposed animals. The present workconducted, to study the effect of coriander extract on Mercury induced toxicity on glycogen content in the fresh water bivalve Lamellidensconsoinus. The effectwas studied under five groups. Bivalves of Group ‘A’ was maintained as Control, group ‘B’ Bivalves were exposed to chronic LC_50/10 dose of Mercury chloride (0.170 ppm) ,while group ‘C’ Bivalves were exposed to respective chronic concentration of Mercury chloride along with 5 ml/lit of coriander extract for 18 days. Glycogen content in bivalves from all groups were estimated after 6, 12 and 18 days. After 18 days exposure to Mercury chlorideBivalves from ‘B’ group was divided into two groups into ‘D’&‘E’ groups. Bivalves of ‘D’ group were allowed to cure naturally while those of ‘E’ were cured with coriander extract (5 ml/lit). Glycogen content in bivalves from these D & E groups was studied after 6, 12& 18 days. Significant decrease in Glycogen content was observed in ‘B’ group bivalves as compared to group ‘A’ (control). The group ‘C’ bivalves showed more Glycogen content thanthose group ‘B’ bivalves. The group ‘E’ bivalves showed fast recovery and more Glycogen content with coriander extract than those of group ‘D’ bivalves which were allowed to cure naturally. Glycogen content was estimated by anthrone reagent method.
