Abstract :

The Prawn and shrimp samples of were collected from local markets of Virar suburban areas of Mumbai city from June to December 2012. These prawn samples were dried in the laboratory and, the dried prawns were crushed into a fine powder by mortar and pestle and stored in amber colored bottles in vacuum desiccators. These samples were evaluated by Atomic Absorption spectrophotometer for the determination of the ten heavy metals namely Cu, Zn, Mn, Fe, Co, Cr, Ni, Pb, Cd, and Hg. In the present work, the mean values at minimum and maximum concentrations of copper, zinc, iron and chromium in the prawns and shrimp samples are found below the maximum specified acceptable concentration where as Mn, cobalt, nickel, lead, and cadmium these values were found above the maximum specified acceptable concentration as prescribed by WHO. The mean values of the minimum and maximum concentrations of mercury in the prawns and shrimp samples were not detected as these concentrations were either less than 0.001ppm or absent in all the species of prawns and shrimps.
