News Release - Government guidelines across North America, Europe fail to protect lakes from salt pollution human activities, including de-icing in winter

The salinity of freshwater ecosystems caused by road de-icing salts, agriculture fertilizers, mining operations and climate change is increasing worldwide and current water quality guidelines don’t do enough to address the issue, an international study led by Queen’s University and The University of Toledo has found. The research, conducted in collaboration with dozens of scientists across North America and Europe, shows significant damage is being done to freshwater lakes by salt concentrations that are below ranges government regulators have deemed safe and protective of freshwater organisms.
