摘要
为了解包头市固阳县环境空气污染现状,系统分析污染物浓度变化特征,对固阳县2016—2021年环境空气中的SO_(2),NO_(2),PM_(10),PM_(2.5),CO,O_(3)浓度随时间变化特征开展研究.采用空气质量指数法,确定固阳县首要污染物,并提出改善环境空气质量相关措施.结果表明:2016—2021年空气质量相对较好的为2020年,2018年为相对较差年份,3月至5月空气质量指数较大;研究期内臭氧和PM_(10)为固阳县环境空气首要污染物;SO_(2),NO_(2),CO质量浓度表现为冬春季高,夏秋季低.臭氧浓度变化为秋冬季较低,夏季浓度达到最大;PM_(10),PM_(2.5)质量浓度呈春季高夏季低趋势.建议通过调整和优化产业结构与能源结构,构建科学的监督管理模式以及加强污染物的治理力度等措施改善环境空气质量.
In order to understand the current status of environmental air pollution in Guyang County,Baotou City,the characteristics of pollutant concentration changes were systematically analyzed.The study investigated the temporal variation of SO_(2),NO_(2),PM_(10),PM_(2.5),CO,and O_(3) concentrations in the environmental air from 2016 to 2021 in Guyang County.The Air Quality Index method was used to determine the primary pollutants in Guyang County.Then,proper measures were proposed to improve the environmental air quality.The results show that the air quality was relatively better in 2020 and relatively worse in 2018.From March to May,the air quality index was higher.During the studied period,ozone and PM_(10) were the primary pollutants in the environmental air of Guyang County.The concentrations of SO_(2),NO_(2),and CO were high in winter and spring,and low in summer and autumn.PM_(10) and PM_(2.5) concentrations were high in spring and low in summer.It is suggested to improve environmental air quality through measures such as adjusting and optimizing industrial and energy structure,building a scientific supervision and management model,and strengthening pollution control efforts.
