Abstract
The contaminanted aquatic environment may end up into the food chain posing risks to tourists’ health in tourist destination. To assess the health risk for tourists visiting st martine island, the best destination of the tourists, both domestic and foreigner, in Bangladesh, a study has been undertaken to analyze the level of heavy metal contamination from Chromium (Cr), Manganese (Mn),Copper (Cu),Zinc(Zn),Arsenic (As),Cadmium (Cd), Lead (Pb), Mercury (Hg), Iron(Fe), in six mostly consumed fish (L. fasciatus, R. kanagurta, H. nigrescens, P. cuneatus, P. annularis and S. rubrum), and five crustacean species (one shrimp (P. sculptilis) one lobster (P. versicolor) and three crabs (P. sanguinolentus, T. crenata and M. victor) captured at St. Martine Island of Bay of Bengal, Bangladesh . The samples were analyzed for trace metals using Atomic Absorption Spectrometer (AAS) and the concentrations of the metals were interpreted using US EPA health risk model. Muscle and carapace/exoskeleton of shrimp, lobster and crabs were analyzed which containted various concentration of Pb, Hg, As, Cr, Cd, Fe, Cu, Zn and Mn . The hiearchy of the havey metal in marine fishes showed as Fe > Cd > Zn > Pb > Cu > Cr > Mn > Hg. Concentration of Pb in the species R. kanagurta, H. nigresceus and S. rubrum was above the Food Safety Guideline (FSG) by Australia-New Zealand and other legislation in most of the marine fish and crustaceans. Furthermore, crabs showed the highest mean heavy metal concentrations than that of shrimp and lobster. The carcinogenic acceptable ranges were observed in three fish species (R. kanagurata, H.nigresceus, and S. rubrum) and one crustacean species (P. sculptilis) samples.
