Employing the flameless atomic absorption technique a method of general utility is proposed for the estimation of mercury content in fish. The method is based on the reduction of organic/inorganic mercury to elemental mercury using tin(II) chloride as the reductant. Marine and fresh water whole fish samples (wet weight 2-3 kg) of the following common species: Salmon, mallie, mashir, bangha and pamphlet are analysed. The estimated mercury content of these fish is examined in relation to that of the relevant water. A linear regression analysis of the data indicates the potential use of fish as an indicator of a local mercury pollution source.
