Critical Loads of Acidity to Freshwater - Fish and Invertebrates
Chemical criteria have been established for estimating critical loads of acid precipitation to surface waters. Acid neutralization capacity (ANC) was used as chemical component for describing the critical limits for biological indicators. Considerable variations in critical ANC limits are recorded f...
