Article : Additives used in alternative road salts may affect aquatic ecosystems

A new study shows that run-off from de-icing road salts can affect freshwater aquatic ecosystems by increasing certain types of plankton. The study is the first to compare effects of the most popular road salt, sodium chloride, with the effects of alternative salts and additives used to increase de-icing efficiency. Based on their findings, the researchers recommend that magnesium
chloride and salt additives are used cautiously near water bodies.
