Assessment of Lead and Arsenic Bioaccumulation Factors in Liza parsia Fish from the Midnapore Coastal Zone, West Bengal
Keya Bhattacharya | Soumendra Nath Talapatra [13]
Abstract: The objective of the present study was to detect Pb and As concentration in water and sediment along with bioaccumulation factor for the vital organs viz. liver, gill and muscle of Parse fish (Liza parsia) inhabited in Midnapore coastal zone, West Bengal as per three seasons viz. Pre - monsoon, monsoon and post - monsoon. The metal (loids) concentrations were estimated by using atomic absorption spectrophotometer (AAS). In the present results, Pb content in estuarine water was exceeded the surface water quality standard in all seasons but As was observed within the limit for all seasons. Both Pb and As content in sediments were within the prescribed limit. But the Pb and As accumulation in the vital organs of studied fish were exceeded the prescribed limits. Moreover, Pb and As accumulation were observed higher in gill and liver compared to muscle, which is within the permissible limits. It is concluded that still muscles of this fish specimens are safe related to metal (loids) accumulation. It is suggested further to analysis the physico - chemical parameters of the habitat as well as study with other fish species with these metal (loids).
