| This study was performed for comparingthe accumulation of heavy metal mercuryin fish muscle tissue of the Southern meager (Argyrosomushololepidotus) and its correlation with age, total length and total weight inthe Persian Gulf waters in 1391. Sampling of fishing stations located in Abadan and Hendijancarried outduring the months of March to November. 80 samples were collected in 5 age groups. After samplingof muscle, compound samples were obtained according to standard methods Moopam. Mixedsamples were wet-chemical digestion method and Concentration of mercury by atomic absorption was performed with a Perkin Elmer 4100 Model. Mean concentrations of mercury in the southern meager muscle tissue were 84.86±19.92 μg/kg dry weight (P<0.05). The highest mercury concentration among different age groups was 118.5±11.61 μg/kg dry weight at age 8-10 -year - old. There was a positive correlation betweenconcentration of mercury with total length and total weight withoutsignificant difference (P≥0.05). The relationship between mercury concentration and age was positive and significant (P-value = 0.0032). Average metal concentrations in flesh tissues was lower thanWHO and the FDA. |
