Abstract

In this study the possible health effects of consumption of benthopelagic (Johnius Belangerii (C); JB) and demersal (Cynoglossus Arel; CA) fishes were evaluated. These fish species living in the Musa estuary (the biggest estuary in the south of Iran and in the northern coastline of Persian Gulf) are likely to be polluted with Hg, V, Ni and Tl. The food frequency questionnaire (FFQ) was used to estimate fish intakes in the residents of Mahshahr city. Also, heavy metal concentrations were determined in fishes and compared with the maximum permissible levels (MPLs). The bioaccumulation factor (BAF) showed high bioaccumulation ability for Hg and Tl in both fish spices. The ratio of TDI/EDI showed the importance of the health hazard by both fish consumption. Also, Hg and Tl in fishes had a higher calculated target hazard quotient (THQ) than the limits. Regarding with the high possibility of serious health concerns associated with Hg and Tl contamination in the Musa estuary, it is suggested to do appropriate and urgent actions by the governors. © 2020
