Abstract
    The influence of the mercury compounds Hg2Cl2, HgCl2, and CH3HgCl as measured by egg mortality, preadult mortality, and development time, was studied on the marine nematode Monhystera disjuncta. A significant influence on egg, juvenile, and preadult mortality was observed for Hg2Cl2 and HgCl2, while CH3HgCl did not cause egg mortality. It was concluded that the juvenile mortality is the most sensitive index for the chronic stress. No apparent changes in the development time occurred. The acute toxicity of the above mentioned mercury compounds, measured as the 96h LC50-values, were calculated for both adult females and males.
