Abstract

Shrimps are one of the most important seafood sources for humans. Heavy metals accumulated in the body of shrimp can be transmitted to humans in the food chain. The present study was done in 2017 to compare the accumulation of heavy metals Copper (Cu), Iron (Fe), Lead (Pb), Cadmium (Cd), Tin (Sn), Arsenic (As) and Mercury (Hg) in edible tissue of Indian white shrimp in the fishing grounds of the Makoran coasts. For this purpose, 60 shrimps were harvested from Konarak, Beris and Pasabander. After biometry and preparation of samples and measurement of metals, the mean concentrations of Cu, Fe, Sn, Pb, Cd, As and Hg were 2.13 ± 0.28, 2.76±0.13, 1.77±0.30, 0.24±0.05, 0.03±0.001, 0.32±0.05,0.02±0.001 μg/g dry weight in muscle tissue of the shrimp. Comparing the stations showed that the Bris area had a significant difference except for mercury and iron in other metals (P <0.05). Comparing the results with some international standards, such as the World Health Organization (WHO) and American Food and Drug Administration(FDA), shows that the concentration of all the tested elements is less than global, so shrimp consumption is not hazardous to human health in the sampled areas.
