Selenium and mercury distribution in porcine tissues and their subcellular fractions from a mercury-polluted area of Guizhou Province and from a not mercury-exposed area of Beijing in China have been studied with neutron activation analysis and hydride generation-atomic fluorescence spectrometry. Both the selenium and mercury levels are higher in Guizhou porcine tissues and their subcellular fractions than those in Beijing. These two elements are highly enriched in kidney and liver of Guizhou pig, while selenium is only enriched in the kidney of Beijing pig. Exposure of mercury may result in redistribution of Se and Hg in vivo. The Hg/Se molar ratio of the subcellular fractions is very low in the case of relatively low mercury level and gradually reaches to a high constant value with increasing level of mercury, which implies that selenium and mercury may form some special complexes in the organisms.
