Acid rain in China.
Rapid industrialization has put citizens and ecosystems at risk. Acid rain emerged as an important environmental problem in China in the late 1970s. Many years of record economic growth has been accompanied by increased energy demand, greater coal combustion, and larger emission of pollutants. As a result of significant emissions and subsequent deposition of sulfur, widepsread acid rain is observed in southern and southwestern China. In fact, the deposition of sulfur is in some places higher than what was reported from the back triangle in central Europe in the early 1980s. In addition, nitrogen is emitted from agriculture, power production, and a rapidly increasing number of cars. As a result, considerable deposition of pollutants occurs in forested areas previously thought to be pristine. Little is known about the effects of acid deposition on terrestrial and aquatic ecosystems in China. In this article, we present the current situation and what to expect in the future, largely on the basis of results from a five year Chinese Norwegian cooperative project. In the years ahead, new environmental challenges must be expected if proper countermeasures are not put into place.
