韩山师范学院PM_(2.5)的移动监测与分析

Mobile monitoring and analysis of PM_(2.5) in Hanshan Normal University

利用Sniffer4D灵嗅超本地大气移动监测系统于2021年9月和10月对潮州市韩山师范学院东丽A、B、C校区大气颗粒物进行了步行移动监测和分析。结果表明:校园内的PM_(2.5)日均浓度范围是4.46~47.75μg/m^(3),达到了环境空气质量的二级标准75μg/m^(3);PM_(2.5)对PM_(10)的贡献较大,PM_(2.5)/PM_(10)比值平均为90%。此外,高浓度PM_(2.5)可能与东山路和卧石路的机动车尾气排放、施工扬尘以及美食街烹饪油烟污染源相关。

The atmospheric particles in Dongli A,B and C campuses of Hanshan Normal University in Chaozhou were monitored and analyzed by using the Sniffer 4D super-local air movement monitoring system in September and October 2021.The results show that the daily average concentration of PM_(2.5) in the campus ranges from 4.46 to 47.75μg/m^(3),reaching the secondary standard of ambient air quality 75μg/m^(3).PM_(2.5) contributes much to PM_(10),with an average ratio of PM_(2.5)/PM_(10) of 90%.In addition,the high concentration of PM_(2.5) is likely to be related to vehicle exhaust emissions and construction dust on Dongshan Road and Woshi Road,and cooking oil fumes in Food Street.
