Abstract

The aims of this study were to determine the permissible consumption limitsand risk assessment of three fishesspecies Platycephalus indicus, talamparoides Carangoides,and Liza abu in Shif Island, Bushehr province.  In this study, 30 fishes of 3 species (Platycephalus indicus, talamparoides Carangoides, Liza abu) were collected from Shif Island coastal waters using a fishing boat. According to the results, the permissible consumption limits(CRlim)ofPlatycephalus indicus for Ni, Mn, Zn, Cu and Fe were 0.21, 5, 0.57, 0.23 and 2 kg/day respectively, for talamparoides Carangoides were 0.29, 3, 0.66, 0.37 and 1 kg/day respectively and forLiza abu  were 0.20, 2, 0.56, 0.76 and 1 kg/day respectively. The maximum daily and weekly intakes were obtained for Fe in Liza abu, and the minimum was found for Manganese in Platycephalus indicus. In this research, the metal values were lower than the world standard, except for Mn in Liza abuand Ni in three fishes species that the high concentrations of Ni in fish species may cause problems for the inhabitants of the island in long time. The food risk assessment of fishes species indicated that the consumption of these fishes with current levels (20 gr/day) in stand of Fe, Cu, Zn, Mn and Ni do not possess a risk to consumers. But due to the permissible limit values, excessive consumption of these species may cause problems for the consumer.
