ABSTRACT

Objective To study the change tendency of air pollutants in Shenzhen, China in 2002-2005, further, to explore the relationship between disease spectrum and air pollution. Methods The daily mean concentration of SO2, NO2 and PM10 in 2002-2005 in eight environmental monitoring sites were determined according to Ambient Air Quality Standard. Results Air concentrations of SO2, NO2 and PM10 increased yearly in 2002-2004, from 0.018 3 mg/m3 to 0.023 4 mg/m3, 0.050 1 mg/m3 to 0.072 5 mg/m3, 0.061 0 mg/m3 to 0.075 7 mg/m3, respectively, however, the concentrations of the three indexes decreased in 2005. In the past four yeas, average levels of SO2 were under the limit of grade 2 of GB3095-1996, as for PM10, under the limit of grade 2, and most of the concentrations of NO2 were under the limit of grade 3, but in the other two monitoring sites, the concentrations of NO2 in 2004 exceeded the limit of grade 3. The year average concentrations of SO2, NO2 and PM10 in 2002-2005 in the outer region were higher compared with those in the inner region of the special economic zone, except the level of NO2 in 2002. As for the quarter average concentrations of SO2, NO2 and PM10, 1st and 4th were higher compared with 2nd and 3rd. Conclusion The air quality in Shenzhen is better in China, however, more attention should be paid to the pollution of nitrogen oxides and inhalable particle matters.
