Table 1.

Mercury concentrations for fish and seafood. Data presented as geometric mean ± standard error. Percent MeHg⁺ for each species is calculated using geometric mean of individually calculated [MeHg⁺]/[THg]*100.

[THg] – concentration of total mercury.

[MeHg⁺] – concentration of methylmercury.

ppb – parts per billion (μg/kg).

ww – wet weight.

%MeHg – [MeHg⁺]/[THg]*100.
