摘要/Abstract

摘要： 以“奎屯—独山子—乌苏”区域重点城市奎屯为研究区域,利用2013—2015年O₃、VOC_s、NO_x监测数据,探讨奎屯市大气O₃与VOC_s、NO_x之间的关系。结果显示:2013—2015年依次出现33 d、14 d、10 d O₃超标现象,最大日均值分别为0.457 mg·m^-3、0.396 mg·m^-3、0.385 mg·m^-3,夏季O₃污染较重,冬季和夏季O₃浓度值相差近2.5倍;O₃浓度日间变化呈现倒“U”形分布,峰值出现在17:00左右;冬季和夏季VOC_s浓度相差近3倍,VOC_s小时值没有较明显的日变化规律,冬季VOC_s浓度最高而O₃浓度最低,两者反向作用不明显,但NO_x浓度与O₃呈现对称的反向作用,说明冬季奎屯市O₃的生成处于NO_x敏感区而非VOC_s敏感区;夏季VOC_s与NO_x变化趋势基本相同,O₃浓度水平处于高位,两者呈现对称的反向作用,说明夏季奎屯市O₃的生成同时处于VOC_s和NO_x敏感区,O₃生成受VOC_s及NO_x的交替控制。

Abstract: In this paper,the relationships among O₃,VOC_s and NO_x concentrations over Kuytun City,Xinjiang,northwest China during the period of 2013-2015 were analyzed using the environmental monitoring data.Results showed that an apparent overload of O₃ concentration occurred over Kuytun City.O₃ concentration over the city was overloaded for 33,14 and 10 days during the period of 2013-2015,and the daily maximum concentrations of O₃ were 0.457,0.396 and 0.385 mg·m^-3,respectively.The heavy pollution of O₃ occurred in summer,and the value of O₃ concentration was 2.5 times higher than that in winter.The curve of diurnal variation of O₃ pollution was reversely “U-shaped”,and the peak value occurred around 17:00 o’clock.The concentration of VOC_s in summer was 3 times higher than that in winter,and there was no significant diurnal variation.It was observed that the high concentration of VOC_s and low concentration of O₃ occurred in winter.In summer,VOC_s concentration changed with NO_x accordingly,and O₃ concentration was the highest.This study indicated that the O₃ pollution occurred mainly in the sensitive areas of VOC_s and NO_x,and controlled alternatively by VOC_s and NO_x.
