Acid Deposition

This page last reviewed June 10, 2011


Scientific evidence in other parts of the world has shown that atmospheric deposition of sulfur and nitrogen compounds can cause harm to the environment and, thus, may present a threat to California's ecosystems and the health of its citizens. To adequately address this serious concern, the causes and effects of acid deposition in California were studied in two comprehensive State-funded monitoring and research programs. The California Legislature enacted the Kapiloff Acid Deposition Program (KADP) and the Atmospheric Acidity Protection Program (AAPP). These studies examined the atmospheric processes associated with acid deposition and its effects on human health, aquatic ecosystems, forest ecosystems, agricultural crops, and man-made materials. Concentrations of acidic air pollutants in precipitation, fog, and dry-deposited particles and gases were measured in support of the KADP and AAPP by the Air Resources Board's (ARB) California Acid Deposition Monitoring Program (CADMP). The draft report "Final Assessment of the Atmospheric Acidity Protection Program" was presented to the Air Resources Board at their October 26, 2001 meeting. The draft report describes the major findings of the Kapiloff Acid Deposition Program and Atmospheric Acidity Protection Program.
