Mercury concentrations of five species of Antarctic fish collected from CCAMLR Subareas 88.1 and 88.2
Abstract: The mean mercury level for the D. eleginoides 1998 sample was 0.43 mg/kg-1, which is ... slightly lower than the permissible level of 0.5 mg/kg-1 set by the New Zealand Food Safety Authority ... (NZFSA). In contrast, mean levels of mercury for D. mawsoni were 0.10 mg/kg-1 in the 1998 samples and ... 0.16 mg/kg-1 in the 2006 samples, both of which are well below the permissible level. Mercury levels ...
