校园内空气总悬浮颗粒物含量的空间变换和趋势评估

Space-time Transformation and Trend Assessment of Total Suspended Particles in Campus1

针对佳木斯大学校区环境,测定空气中总悬浮颗粒物的含量,并分析其空间变化,进而了解大学校区内空气质量状况,对日后的空气质量研究提供依据。对四个校区进行定点采集,采用中流量空气采样-称重法,计算得总悬浮颗粒物的浓度,取其均值总悬浮颗粒物含量。以重量法的计算结果为统一标准,其平均含量为0.273mg/m^3。将所得结果与《环境空气质量标准》(GB3095-2012)相比较,得出校园内总悬浮颗粒物的含量达到国家2级标准。

The content of total suspended particulates in the air was measured within the campus of Jiamusi University and the spatial changes of the analyzer. The results of the experiment could further realize the air quality status of Jiamusi University. In addition, the experimental results could also provide a basis for the future air quality research. The four campuses of Jiamusi University were collected and the concentration of total suspended particulates was calculated by weight method and medium flow sampler method. The total suspended particulate matter content in different spaces was compared and analyzed. The average weight of the method was 0. 273mg / m^3. The results compared with the ＂ Ambient Air Quality Standards＂ （ GB3095 - 2012 ）, and it was found that the content of suspended particulate had reached the second level of Standardization Administration of China.
