Changes in Air Quality of the Yuxi City Urban Area

Abstract:

Air pollution causes health problem. The paper simply analyzed the changes of air quality in the Yuxi city urban area from 2006 to 2012. In the Yuxi city urban area between 2006 and 2012, SO₂ levels increased about 43.9 percent; NO₂ levels increased about 13.3 percent; PM10 levels in 2012 decreased about 1.5 percent. By evaluating the air quality in the Yuxi city urban area, the results showed that air quality index was the maximum in 2009, and the quality of the air in Yuxi became worse from 2006 to 2012, air pollution in 2009 was the heaviest between 2006 to 2012. After adopting P.R.C EPA air quality standards (GB3095-2012) in 2013, the first air pollutant in Yuxi is PM₁₀, and then it is SO₂ among SO₂, NO₂ and PM₁₀.Much should beend done to reduce the amount of PM₁₀ and SO₂ released.
