Abstract

Heavy metals constitute one of the most hazardous substances that could be accumulated in biota coming from human activities such as agricultural and industrial wastes. This paper aims to study the levels of some of the most common heavy metals in muscles of the fish caught in the Karun River (Ahvaz, Iran) and to assess the health risks associated with their consumption.Design/methodology/approachIn present study, the concentrations of three heavy metals (Pb, Cd and Cu) in the muscle of highly consumed fish species Ctenopharyngodon Idella (Cyprinidae) collected from three selected markets (Khoram Kooshk, Ahvaz-e Qadim and Padad Shahr; total number of samples was 45) in Ahvaz city and human health risk associated with their consumption were detected by Inductively Coupled Plasma Mass Spectrometry (ICP-MS).FindingsThe results indicated that the highest and lowest accumulated metal concentrations were related to Cu (20.36 ± 0.84) and Cd (0.53 ± 0.02), respectively. In addition, the mean difference for Pb and Cu across two pairwise of sampling sites were significant (Ahvaz-e Qadim and Khoram Kooshk, P for Pb = 0.025, P for Cu = 0.033; Ahvaz-e Qadim and Padad Shahr, p for Pb = 0.018, p for Cu = 0.039). The estimated daily intake of all metals in muscles of fish in this study were below the legal limit, and mean differences were not statistically significant among the sampling sites, except for Cu (Ahvaz-e Qadim and Khoram Kooshk, p = 0.048; Ahvaz-e Qadim and Padad Shahr, p = 0.041). Target hazard quotient values were also all below 1.Originality/valueIt can be concluded that the fishes from Ahvaz city markets are comparatively clean and do not constitute a risk for human health.
