长春市净月大学城区PM_(2.5)及PM_(10)空间分布特征初步研究

Study on Spatial Distribution Characteristics of PM_(2.5) and PM_(10) in Jingyue University Town in Changchun

为掌握长春市主城区净月大学城区PM_(2.5)和PM_(10)质量浓度的空间分布特征,选择了8处室外环境空间,使用YT-HPC3000C型主动采样激光粉尘仪,对各样点进行了质量浓度监测。结果表明,与区域内室外8处样点的PM_(10)质量浓度,以轻轨站处为最高,其他7处样点均好于二级标准;室内4处样点的PM_(2.5)和PM_(10)的质量浓度,食堂均未达标,其他3处样点均达标。在室内各样点,PM_(2.5)与PM_(10)的浓度空间分布呈现随高度升高而降低的趋势;在室外各样点,PM_(2.5)与PM_(10)的浓度分布与其所处垂向位置无明显相关关系。

To master the spatial distribution characteristics of PM2.5 and PM10 mass concentration in Jingyue University town located in the southeast of Changchun City and explore its potential impact on the health of local residents. The eight outdoor environments were selected,namely,the sun light rail station square,forest before the second dining room,the first dining room,a former field,basketball court,students baths,track and backstreet business district,using the YT- HPC3000 C instrument to monitor the various points on PM2. 5and PM10 concentration. The light rail station is the highest area in the eight samples in PM10 concentration.The other seven samples are better than the secondary standard. Among the four indoor samples,the dining room is not up to secondary standard both in PM2. 5and PM10 concentration. The other three samples reached the secondary standard. PM2. 5and PM10 spatial distributions of every indoor environment decreases as height increasing. PM2. 5and PM10 of every outdoor environments have no significant correlation with its vertical position.
