Accumulation of metals in some arthropods, mollusks and marine fishes

The concentration of metals accrued in water, sediment, insects (viz. C. megacephala and P. americana), crustaceans (viz. P. monodon and S. serrata), mollusk (viz. S. pharaonis) and marine fish (viz. L. calcarifer) collected from Kuakata, Patuakhali were evaluated using flame (Varian AA240FS), hydride-generation (Varian AAS240FS) atomic absorption spectrophotometer and Zeeman Varian graphite atomic absorption spectrophotometer (Varian AA240). Concentration of metals (viz. Arsenic, Chromium, Cadmium, Copper, Lead and Zinc) detected highest in sediment (14800 ppb) , Scylla serrata (250 ppb), water (411280.7 ppb), Chrysomya megacephala (21035 ppb), sediment (14800 ppb) and Chrysomya megacephala (110345ppb) respectively and lowest in water (2.45 ppb), Periplaneta Americana (20 ppb), Sepia pharaonis (1538ppb), water (3434 ppb), water (184 ppb) and Lates calcarifer (7656 ppb) respectively.
