In the present study, the rise assessment of heavy metals includes copper(Cu), iron(Fe), cadmium(Cd), sternum(Sn), arsenic(As) and mercury(Hg) for the consumers of Indian white shrimp caught from different coasts of Chabahar was evaluated. In 2017, 180 shrimp specimens were caught from the coasts of Konarak, Beris and Gwadar (Chabahar Province). In the laboratory, the samples had dried, digested and subsequently the metals concentration was measured using spectrophotometer. The estimated daily intake of metals to the body of the consumers and the target hazard quotient were done based on the method, developed by the World Health Organization. Among different metals, iron had the highest concentration with 2.72 μg/g, while the lowest accumulation of metals was recorded for mercury with 0.01 μg/g. The ranking order of metals accumulation in the muscle of shrimp were as Fe, Cu, Sn, As, Pb, Cd, Hg. The highest amount of daily intake (μg metal/kg person/ day) was observed for arsenic (0.20) while the lowest was for Tin(sn) (0.0006). Target hazard quotient (THQ) and total target hazard quotient (TTHQ) for all metals were lower than 1. The results showed there is not any health risk for the consumers of Indian white shrimp due to accumulation of copper, iron, cadmium, stannum, arsenic and mercury in the shrimp.
