The acidity of precipitation is the net sum of the acidity or alkalinity of each chemical component. Acid precipitation at nine sites in the Los Angeles basin of southern California was collected and analyzed to determine its chemical composition. Concentrations of major cations and anions, as well as trace species, were identified. Variations of sea salt, soil dust, ammonia, ammonium, and sulfate concentrations agreed with source distributions, scavenging, and advection patterns. Chemical equilibrium models related the chemical composition of precipitation with atmospheric concentrations of sulfur dioxide, nitrogen dioxide, nitrogen oxide, nitric acid, and ammonia.
