The determination of Cadmium concentrations in Caspian kutum (Rutilus kutum) tissues and assessment of the food consumption risk in the southern coast of Caspian Sea

Seafood are considered as the important sources of high-quality protein, but they can contribute significantly to human dietary risk. The aim of the present study was: detecting of the concentrations of cadmium (Cd) in skin and muscle tissues of rutilus kutum; comparing the concentration of Cd in tissues of male and female; and finally assessing the food consumption risk in southern coast of the Caspian Sea. The thirty specimens of Caspian kutum were obtained from southern coast of Caspian Sea. After digestion of specimens, concentration of Cd were detected by atomic absorption spectrophotometer. The mean concentration of Cd in skin and muscle tissues were 0.45±0.38 and 0.38±0.06 µg/g wet weight, respectively. The result of statistical analyze showed deference in Cd concentration in skin and muscle tissues (p<0.01). Also, there was no any significant deference in Cd concentration between male and female. THQ (2×10-4) was lower than allowable dose proposed by EPA. Daily and weekly intake of Cd in edible tissues were 1.42 µg per day and 9.97 µg per week, respectively, that showed that the estimated amount of Cd intake is lower than the maximum acceptable level permitted by the joint FAO/WHO expert committee. The maximum allowable consumption rate for adults and children were 0.16 and 0.03 kg per day, respectively. The maximum allowable consumption rate in meal were 21.79 and 4.51 meal per month for adults and children, respectively. The present study showed that Caspian kutum meat is safe to consume and does not threaten the health of consumer with current consumption rate.
