xx空气污染与健康风险研究.doc

空气污染是现阶段我国广大城市面临的主耍问题，随着检测手段的进步，pm2.5逐步被广 大居民所重视，相对于PMW，PM2.5对民众的呼吸系统危害更大，引起了普通民众和科学界的 广泛关注。为了深入了解xx空气污染对城市居民的健康影响，本论文通过采集xx市2016到 2017年的7个污染观测点的空气质量数据，对PM2.5、PM,o NO2、03、CO和SO2浓度监测 数据进行整理，计算出AQI，然后研究了污染物浓度的周循环变化规律，周末，工作円，春节及 国庆前后的污染物变化的差异，再excel中编写代码完成对数据的处理过滤，最后对空气污染 对健康风险的总结。 关键词：空气质量；PM2.5污染；健康影响；数据过滤 ABSTRACT Air pollution is the main problem facing the vast cities in China at this stage，With the progress of detection means，PM2.5 gradually by the majority of residents attention, Relative to the PM]o， PM2.5 greater harm to the public’s respiratory system, causing the general public and the scientific community of widespread concern.In order to understand the health effect of Ningbo air pollution on urban residents, this paper collected the air quality data of seven pollution observation points in Ningbo from 2016 to 2017, PM2.5, PM10, NO2, O3 and SO2 concentration monitoring data were sorted out to calculate AQI.And then studied the changes of the cycle of pollutant concentration cycle, the weekend，working days，the Spring Festival and the National Day before and after the difference in the changes in pollutants.Then write code in the Excel, complete data filtering processing and finally the air pollution on the health risk of the summary.
