Current water quality guidelines aren’t protecting freshwater ecosystems from increasing salt pollution due to road de-icing salts, agriculture fertilizers, and mining operations, according to an international study that included researchers at Rensselaer Polytechnic Institute. Published today in the Proceedings of the National Academy of Sciences (PNAS), the research shows that freshwater salinization triggers a massive loss of zooplankton and an increase in algae—even when levels are within the lowest thresholds established in Canada, the U.S., and throughout Europe.
