The tolerance of Bathyporeia pilosa Lindstrom (Amphipoda: Haustoriidae) to organic and inorganic salts of mercury

Add time:09/02/2019    Source:sciencedirect.com

Toxicity tests of mercuric chloride and ethyl mercuric chloride were run on Bathyporeia pilosa. One-hundred-and-eight factorial combinations were analysed for each mercurial compound (three salinities, three temperatures, two age groups and six mercury concentrations). These were complemented by an investigation on the uptake and concentration potential of these two compounds by B. pilosa. Toxicity of the inorganic and organic mercury was seen to be directly related to both concentration and temperature and inversely related to salinity and age. Sublethal effects were studied and related to the four parameters investigated. Accumulation of the organic mercury compound was almost twice as rapid as that of the inorganic form, although death occurred where animals contained very similar levels of mercury.
