遵义市汇川O_3、NO_2和SO_2变化特征分析
|
摘要
根据2015年1月—2017年12月间监测数据,分析了遵义市汇川大气中O_3、SO_2和NO_2浓度变化特征。结果表明,3年间SO_2污染最轻,NO_2次之,O_3污染较重;NO_2与SO_2浓度冬春季要显著高于夏秋季,O_3浓度表现为夏高冬低。夜间建筑施工及渣土车排放对NO_2浓度影响较大,社会生活燃煤排放对冬春大气中SO_2的贡献较大。相关性研究表明,不同天气下各污染物与相对湿度均呈负相关性,多云和晴天NO_2和SO_2浓度与风速、气温呈显著负相关性,而与O_3浓度呈正相关性。
The concentrations of O_3, NO_2 and SO_2 obtained from automatic air monitoring station,from Jan. 2015 to Dec. 2017 in Huichuan District of Zunyi, were analyzed to investigate their temporal characteristics. The results showed that the pollution levels of SO_2 was relatively low,whereas O_3 was relatively high. The atmospheric pollutants had obvious seasonal variation characteristics. The concentrations of NO_2 and SO_2 were significantly higher in winter and spring than in summer and autumn, while the concentration of O_3 was the highest in summer and lowest in winter.Night construction and dump truck emissions had a greater impact on NO_2 concentration, while social life coal-fired emissions contributed significantly to SO_2 in winter and spring atmospheres.Correlation studies showed that there was a negative correlation between pollutants and relative humidity in different weathers. And the concentration of NO_2 and SO_2 in cloudy and sunny days was significantly negatively correlated with wind speed and temperature, which had positive correlation with the concentration of O_3 under the same weather conditions.
