A laboratory study of long-term effects of mine depressurization groundwater on fish and invertebrates
Download1980-01-01
McCart, P. J., Tsui, P. T. P., McMahon, B. R., McCart, J. V.
This study was conducted to determine long-term toxic effects, on selected species of fish and invertebrates, of mine depressurization at concentrations non-lethal in acute toxicity tests. The study also includes chronic toxicity experiments, studies of sublethal effects of groundwater, and a...
