摘    要:目的 分析深圳市2002-2005年空气污染物浓度的动态变化,为进一步研究疾病谱的改变与环境因素变化的相关关系打下基础.方法 收集2002-2005年深圳市8个国控环境监测点空气中SO2、NO2和PM10的日平均浓度,其检测方法依据GB 3095-1996<环境空气质量标准>进行.结果 2002-2004年,空气中SO2、NO2和PM10浓度呈上升趋势(SO2从0.018 3 mg/m3增加到0.023 4 mg/m3,NO2从0.050 1 mg/m3上升至0.072 5 mg/m3,PM10从0.061 0 mg/m3增加到0.075 7 mg/m3),但2005年与2004年比较,均有所下降.SO2年均值达到二级标准,接近一级标准;PM10浓度符合二级标准限值;NO2年均值基本符合三级标准,有2个监测点2004年NO2年平均值超出了三级标准,分别为(0.083 6±0.031 5)和(0.099 6:±0.0444)mg/m3.关外地区空气中SO2、NO2和PM10浓度连续4 a均高于关内(除外2002年NO2浓度,关内为0.052 3 mg/m3,关外为0.0464 mg/m3).空气中SO2、NO2和PM10浓度第一、四季度均值均高于第二、三季度均值.结论 深圳市目前总环境质量尚可,但氮氧化物和可吸入颗粒物污染上升速度快,应引起高度重视,谨防光化学烟雾的发生.

关 键 词:空气污染  SO2  NO2可吸入颗粒物

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.
Keywords:Air pollution  Sulfur dioxide  Nitrogen dioxide  Inhalahle particle matter
