Risk estimation of heavy metals from consumption of silver pomfret and tiger tooth croaker in Hormozagan Province

Authors

Abstract

In the present study, accumulation of manganese, cadmium, zinc, iron and copper in the
commercially fish species (silver pomfret and tiger tooth croaker) caught from Bandarabbas
coasts at 2010 was measured and the risk of daily intake of them in Hormozagan urban
population was estimated. The average concentrations (μ/g dry weight) of manganese,
cadmium, zinc, iron, and copper in the muscle tissue of silver pomfret were 1.248, 0.217,
14.444, 2.397 and 3.300, respectively, while the concentration of them in tiger tooth croaker
were 1.009, 0.403, 12.564, 4.467 and 2.366, respectively. According to fish consumption rate,
urban populations of the province were divided into four groups low, medium, high and very
high. The target hazard quotient (THQ) in each group calculated separately. The THQ of all
groups were much lower than 1 in the two fish. The results showed that urban populations of
the province have not any risk due to accumulation of the studied heavy metals.
