Bio Accumulation Of Chromium, Nickel, Lead And Vanadium In Some Commercial Fish And Prawn From Qatari Waters

Abstract

A total of 150 fish and prawn samples representing the most economically important species were collected during 1995-96 by experimental fishing in three locations covering the coastal waters of Qatar. Fish and prawn flesh were analysed for the oil related metals Cr, Pb, Ni and V. The range of levels in fish were 0.06 -0.64 |Xg g"1, 0.03 - 0.93 (ig g"1, 0.31 - 2.23 |Xg g"1 and ND - 0.232 |ig g"1 for Cr, Pb, Ni and V, respectively;
