    摘要:

    利用邯郸市四个空气质量监测站点,2013~2014连续两年的颗粒物及气态污染物在线观测数据和气象数据对该市大气污染状况进行分析,结果表明:邯郸市大气污染以细颗粒物为主,2013、2014年邯郸市PM2.5年均浓度分别为139 μg/m3和116 μg/m3,为国家二级标准(35 μg/m3)的近4倍和近3倍,2014年较2013年有所缓解,浓度下降比例为16.5%,超标率由2013年的74.4%降低到2014年的66.6%;邯郸市PM2.5浓度的空间分布并无明显差异;PM2.5季节变化规律为冬季> 秋季> 春季> 夏季,PM10季节变化规律为冬季> 春季> 秋季> 夏季;邯郸市PM2.5PM10在一周内的浓度差异均较小,说明邯郸市污染物排放的周变化不明显,工业等排放较为稳定的行业占其排放的主导地位;与气象条件的相关性分析表明,邯郸市四季中静风频率最高,邯郸市的风向主要集中在从东到南到西这一方向带上,河南、山东、山西三省对于邯郸市颗粒物的贡献较大。

    Abstract:

    The status of air pollution in Handan city was based on the online observation data of atmospheric particulate matters and gaseous pollutants at four air quality monitoring stations during 2013 and 2014, as well as the meteorological observation data. It is found that the fine particulate matters were the key air pollutant in Handan. The annual average PM2.5 concentrations in 2013 and 2014 were respectively 139 μg/m3 and 116 μg/m3, which were about 4 and 3 times of the national grade II standard (35 μg/m3). Comparing with 2013, the PM2.5 concentrations in 2014 was reduced by 16.5%. In addition, the ratio of the days exceeding the standard dropped to 66.6% in 2014 from 74.4% in 2013. There was no obvious difference in the spacial distribution of PM2.5 concentration in Handan. The PM2.5 concentration was highest in winter, followed by autumn, spring and summer, while the PM10 concentrations were in the order of winter> spring> autumn> summer. There were no clear differences in the concentration of PM2.5 and PM10 in a week, indicating that weekly changes are not obvious in the pollutant emissions and the relatively stable pollutant emission sectors, e.g., industries, played a key role. Correlation analysis between the meteorological condition and the pollutant concentrations indicated that the calm wind had the highest frequency in four seasons in Handan, and the wind direction was concentrated in the direction zone from the east to the south and to the west. Henan, Shandong and Shanxi contributed more to particulate matters of Handan.
