阿克达拉大气本底站污染物的总体特征变化

The overall variation characteristics of Akedala atmospheric background station of pollutants

通过分析2010—2016年阿克达拉大气本底站三种污染物的总体特征得出:阿克达拉大气本底站的PM 10和NO 2年平均质量浓度呈上升趋势,SO 2呈下降趋势;PM 10质量浓度在2014年达到峰值,2010年处于最低;NO 2年平均质量浓度在2015年达到最大值,2010年最低;SO 2年平均质量浓度在2011年达到最大值,2014年最低;PM 10质量浓度峰值在2月、4月和12月,其质量浓度分别为0.013 0 mg/m 3、0.012 6 mg/m 3和0.012 7 mg/m 3,7月最低,仅为0.007 1 mg/m 3;PM 10质量浓度在春、冬季较高,秋季次之,夏季最低;NO 2质量浓度在春、冬季最高,夏季大于秋季。

Based on the characteristics of three pollutants in Gram dara from 2010 to 2016,it s found that the annual mean mass concentrations of PM 10 and NO 2 is basically on the rise,while SO 2 shows a downward trend.The maximum value of PM 10 in Gram dara occurred in 2014,while the minimum value occurred in 2010;The maximum value of NO 2 occurred in 2015,while the minimum value occurred in 2010;The maximum value of SO 2 occurred in 2011,while the minimum value occurred in 2014.The pollutant concentration of PM 10 in Gram dara was highest in February(0.013 0 mg/m 3),next was in December(0.012 7 mg/m 3)and April(0.012 6 mg/m 3),while the lowest is in July(0.007 1 mg/m 3).The pollutant concentration of PM 10 was highest in Spring,next in winter,third in autumn,and lowest in summer,while for NO 2,it s high in spring and winter,and summer is higher than autumn.
