The results of a study show that the effects of toxic, saline seepage waters are “probably due to the electrical conductivity of the mine waste waters.” The researchers studied two tropical freshwater species to determine if the toxicity of saline seepage from mines was due to its major ion constituents. Specific major ion constituents were not clear drivers of toxicity. Currently, elevated major ions (salinity) are recognized as key contributors to the toxicity of many mine waste waters.
