摘要：为了深入研究观察上海市奉贤区化学工业区空气质量、判定化学工业区空气质量是否达到国家规定的二类环境空气功能区的质量要求，并且分析出影响空气质量的因素。对该工业区在重点企业边界进行布点，对每个点位的PM2.5、PM10和TSP进行测量，测量6天，并记录测量时的气象情况。结果表明：在20个点位连续6天的监测中，总悬浮颗粒物TSP最小值为86.6，最大值为229.5，平均值为132.52，所有点位均达标；PM10最小值为71.8，最大值为241.4，平均值为121.67，按平均值未超标，按最大值为超标，超标率为47%，最大超标倍数为0.61；PM2.5最小值为31.4，最大值为157.1，平均值为79.66，按平均值和最大值均超标，超标率为50%，最大超标倍数为1.09；TSP与PM10的总相关性方程为y = 1.075x - 24.12，相关系数为0.97，相关性显著；9号、10号和16号点位的PM10超标严重，最大超标倍数分别为0.54、0.61、0.53倍。15号、18号和19号点位的PM2.5严重超标，最大超标倍数分别为1.08、1.09、0.99。需要对企业进行相应的技术整改，减少挥发性物质和细小颗粒物的排放。

Abstract：Analysis of Air Quality and Source resolution in Chemical Industrial Park in Fengxian District

In order to thoroughly study the air quality in the chemical industrial zone of Fengxian District, Shanghai, and determine whether the air quality of the chemical industrial zone meets the quality requirements of the Class II ambient air function zone specified by the state, and analyze the factors affecting air quality. The points was deployed on the borders of key enterprises of the industrial zone, and PM2.5, PM10, and TSP at each site were measured, measured for 6 days, and the meteorological conditions at the time of measurement were recorded. The results showed that the TSP minimum value of total suspended particulates was 86.6 and the maximum value was 229.5 in the 20-point continuous monitoring for 6 days. The average value was 132.52. All the points were up to standard; PM10 minimum value was 71.8, and the maximum value was 241.4. The average value is 121.67. According to the average value is not exceeded, according to the maximum value is exceeded, the over-limit rate is 47%, the maximum exceedance multiple is 0.61; the PM2.5 minimum value is 31.4, the maximum value is 157.1, the average value is 79.66, according to the average The values and maximum values were all exceeded, the over-standard rate was 50%, and the maximum over-standard multiple was 1.09; the total correlation equation between TSP and PM10 was y = 1.075x - 24.12, the correlation coefficient was 0.97, and the correlation was significant; No. 9 and No. 10 The PM10 at the 16th point exceeded the standard, and the maximum multiples exceeded 0.54, 0.61, and 0.53 times, respectively. PM2.5 at points 15, 18, and 19 were severely exceeded, and the maximum multiples were 1.08, 1.09, and 0.99, respectively. Need to carry out corresponding technical rectification of the company to reduce the emission of volatile substances and fine particles.
