Abstract:Acute lethal toxicity tests with mussels using mercury and mercury-selenium treatments showed that best protection was obtained by simultaneous addition of selecnium on an equimolar basis with mercury. Simultaneous addition of a high concentration of selenium proved to be more toxic than the Hg alone treatment. Analyses of the mercury in the soft-tissues in the mussels showed that some form of Hg/Se interaction did take place whilst simultaneous addition of a low concentration of selenium on an equimolar basis with mercury did not produce a redistribution of mercury in the three different tissues analysed for mercury accumulation.
