acid precipitation

Quick Reference

(mist, fog, rain) Syn: acid deposition. Atmospheric acid aerosols are removed by wet deposition (rain, snow, mist, fog) or dry deposition of particles on vegetation. This is harmful to aquatic and terrestrial ecosystems, to the fabric of many buildings, and to the human respiratory system, aggravating and perhaps causing chronic bronchitis and emphysema in populations living in smoky industrial areas. This is a serious environmental and public health problem in many urban communities with heavy traffic and industry. See also smog.
