HEAVY METAL CONCENTRATIONS IN DIFFERENT BODY PART OF CRAB, BARYTELPHUSA GUERINI FROM GODAVARI RIVER
The concentration of heavy metals Arsenic (As) and Chromium (Cr) in hepatopancreas, gills, muscle and whole body of crab, Barytelphusa guerini was carried out during different seasons summer, monsoon and winter in order to ascertain the pollution status of the river.

The level of As in muscle, gills, hepatopancreas and whole body in summer, monsoon and winter seasons was found that higher than the recommended maximum allowable standards in food. Where as Cr level in muscle and gills in summer seasons, hepatopancreas and whole body in monsoon and muscle and whole body in winter season were higher than the recommended maximum allowable standards in food. The level of Cr in muscle (monsoon), gills (monsoon and winter), hepatopancreas (summer and winter) and whole body (summer) were lower than the standards.
