摘      要：Objective:To determine the concentration of heavy metals(Cd,Cu,Fe,Ni,Pb and Zn)in the liver,gills and muscle of Liza aurata(***)collected from the Kerkennah *** target hazard quotient was also used as an indicator of human health risks associated with fish ***:The sample was collected from Kerkennah Islands(Gulf of Gabes,Tunisia).Heavy metals in *** tissues(gills,liver and muscle)were analysed with an atomic absorption spectrometer(PerkinElmer).Results:As expected,muscle always possessed the lowest concentrations of all *** maximum concentrations of Cd(0.52 mg/kg wet weight),Cu(5.43 mg/kg wet weight),Fe(115.27mg/kg wet weight)and Zn(112.20 mg/kg wet weight)were measured in the liver,while the highest Ni(1.54 mg/kg wet weight)and Pb(1.43 mg/kg wet weight)were recorded in *** target hazard quotient through consumption of fish and calculated by adding the inividual target hazard quotient was below 1,indicating that there was no significant potential health risk associated with consumption of ***:*** from the Kerkennah Islands may be suitable for human consumption.
