Plotting of Acid Rain and Sulfur Dioxide Pollution Control Zones and Integrated Control Planning in China

The distribution and characteristics of acid rain and SO₂ pollution were presented, indicating that the areas with sulfur deposition over critical loads reached 21.9% of the territory in 1995. In order to control the acid rain and SO₂ pollution effectively, the Acid Rain Control Zone and SO₂ Pollution Control Zone (Two Control Zones for short) were designated based on the analysis of sulfur deposition. The corresponding integrated pollution control planning was formulated based on the life cycle approach of sulfur in coal and the technical options for SO₂ mitigation were also recommended for different sources such as coal industry, power industry, industrial boilers and kilns, and household stoves. Based on the countermeasures suggested, the SO₂ would be reduced by about 4.92Mt/yr during 2001–2005 and by 4.16Mt/yr during 2006–2010.
