Background and purpose: Fish and seafood are considered as important sources of high-quality protein, minerals and polyunsaturated fatty acids, but they can contribute significantly to human dietary exposure to environmental pollutants. This study was carried out to assess the concentration of Pb in kutum as the most consumed fish and to determine the estimated daily/weekly intake (EDI/EWI) for comparisons to the tolerable daily/weekly intake (TDI/TWI). Materials and methods: Forty kutums were collected from Bandar Anzali and Roodsar stations, Iran, during January 2012. After preparation and chemical digestion, Pb concentration was determined using Furnace Atomic Absorption Spectrophotometry (SHIMADZU AA/680). Results: The mean accumulated concentrations of Pb in the kutum from Bandar Anzali and Roodsar stations were 2.55 ± 0.54 and 1.66 ± 0.25 mg/kg dry weight, respectively. The observed EDI and EWI of Pb from Bandar Anzali and Roodsar stations were 0.001-0.009 and 0.0009-0.006 mg/kg, respectively. Conclusion: The observed EDI and EWI of Pb in the kutum from Bandar Anzali and Roodsar stations were lower than stipulated guidelines by the FAO/WHO Joint Expert Committee and therefore, were not considered to pose adverse effects to consumers.
