The concentration of meHg in freshwater fish and seafood was investigated, as well the consumption patterns by different demographic groups (age, ethnicity, gender). A potential alarm for human health hazards also assessed, results were compared to provisional tolerable weekly intakes (PTWIs) hazard quotient parameter (HQ). showed that levels 67 species ranged from 0.013 0.252 mg/kg wet weight (WW) with significant differences between (χ2KW = 49.09; p < 0.001). Median concentrations descending orders are follows: demersal (0.1006 WW) > pelagic (0.0686 0.045 cephalopods (0.0405 crustaceans (0.0356 WW). revealed older population (> 40 years old) consumed significantly (p 0.000) more younger generations elderly highest amounts (104.0 ± 113.0 g/day). adolescents (10-17 than double amount both cephalopod crustacean populations 0.05). Malay ethnic (96.1 99.6 g/day) higher other ethnicities, similar male subjects (95.2 102 g/day; 0.026) when female (86 96.3 estimated intake (EWI) values below 1.6 µg/kg BW/week, recommended Joint FAO/WHO Expert Committee on Food Additives (JECFA) all factors except consumers at 75th percentile above. Consumption marine contributed a value PTWI (the range: 0.2988-0.6893 BW/week) but adolescents, where (0.3488 BW/week or 21.8% PTWI) (0.504 31.5% PTWI). this study HQ overall exceeded one. This cephalopods, thus indicating nonacceptable level noncarcinogenic adverse effects.
