环境空气自动监测小微站在浏阳市的应用

Application of Micro Station for Automatic Monitoring of Ambient Air in Liuyang City

采集了2018年11月至2019年3月浏阳市现有的10个环境空气自动监测小微站的空气污染监测数据,分析了浏阳市该时段各区域的环境空气质量;同时,对比分析了小微站与省控站的监测数据,以评价小微站数据的准确性和精确度。结果表明:浏阳市所有小微站的环境空气主要污染物均为PM10,其中永安镇PM10浓度最高;相同点位的小微站与省控站的月平均浓度、AQI指数变化趋势基本一致,但存在3.5%~39.3%的偏差。结合小微站的数据分析情况,目前小微站仅适用于判定小范围区域内空气污染现状和主要污染源,不宜参与浏阳市整个区域环境空气质量评价。

The air pollution monitoring data of 10 micro automatic environmental air monitoring stations in Liuyang City from November 2018 to March 2019 were collected,and the environmental air quality of each region in Liuyang City during this period was analyzed.At the same time,the monitoring data of micro stations and provincial control stations were compared and analyzed to evaluate the accuracy and precision of the data of micro stations.The results showed that PM10 was the main pollutant in the ambient air of all micro stations in Liuyang City,and the concentration of PM10 in Yongan Town was the highest.The monthly average concentration and AQI index of micro stations at the same location were basically the same as those of provincial control stations,but there was a deviation of 3.5%to 39.3%.Combined with the data analysis of micro stations,at present,micro stations were only suitable for judging the status and main sources of air pollution in a small area.It was not suitable to participate in the assessment of environmental air quality in the whole area of Liuyang City.Suggestions were made on the application status and development of micro stations in Liuyang City.
