The accumulation of metals such as arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn) from the samples of insects (viz. Periplaneta americana and Chrysomya megacephala), malacostracan (Penaeus monodon), fishes (Lutjanus johnii and Rastrelliger kanagurta,) and domesticated chicken ( Gallus gallus domesticus) were evaluated in the two areas named Cox's Bazar and Teknaf. The levels of heavy metals were compared with standards of WHO and FAO. All the values except As and Hg were higher than the WHO and FAO recommended values. Pearson's correl...
The accumulation of metals such as arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb) and zinc (Zn) from the samples of insects (viz. Periplaneta americana and Chrysomya megacephala), malacostracan (Penaeus monodon), fishes (Lutjanus johnii and Rastrelliger kanagurta,) and domesticated chicken ( Gallus gallus domesticus) were evaluated in the two areas named Cox's Bazar and Teknaf. The levels of heavy metals were compared with standards of WHO and FAO. All the values except As and Hg were higher than the WHO and FAO recommended values. Pearson's correlation matrix analyses were done to correlate the values of quantified metals for all the samples collected from two areas. Dendrograms of cluster analysis reveal that these metals are interrelated with each other and might have originated from the similar sources.
