燃放烟花爆竹对云南省环境空气质量的影响
|
摘要
利用2016—2018年春节期间(除夕—初六)云南省环境空气中PM_(2.5)、PM_(10)、SO_2、NO_2、CO和O3的质量浓度监测数据,研究了春节期间燃放烟花爆竹对环境空气质量的影响,并采用spearman分析了除夕—初一PM_(2.5)、PM_(10)、SO_2、NO_2、CO小时浓度值变化相关性。结果表明:春节期间(除夕—正月初六)超标天数集中出现在大年初一,首要污染物均为细颗粒物(PM_(2.5));烟花爆竹集中燃放阶段,SO_2、PM_(2.5)、PM_(10)日均值显著升高,O3、NO_2和CO的日均浓度值变化则基本不受其直接影响;总体上PM_(2.5)、PM_(10)、SO_2、NO_2和CO的小时浓度值变化趋势呈正相关,其中SO_2与PM_(2.5)、PM_(10)相关系数均值在0.800左右,高度正相关,这与全省除夕—初一污染物浓度的逐时变化趋势相一致。
Using the monitoring data of PM_(2.5),PM_(10),SO_2,NO_2,CO and O_3 concentrations in the ambient air during the Spring Festival period from 2016 to 2018( New Year's Eve to New Year's Day) in Yunnan Province,the effects of fireworks and firecrackers on the ambient air were studied. The spearman analysis was used to analyze the relationship between the PM_(2.5),PM_(10),SO_2,NO_2,CO hourly concentration changes from New Year's Eve to New Year's Day. The results showed that during the Spring Festival period( from New Year's Eve to the sixth day of the first lunar month),the number of over-standard days appeared on the first day. The primary pollutants were all fine particles( PM_(2.5)). The daily average values of SO_2,PM_(2.5),and PM_(10) during the phase of centralized discharge of fireworks and firecrackers were significantly increased. The daily average concentrations changes of O3,NO_2,and CO were not directly affected. Overall,the hourly concentrations of PM_(2.5),PM_(10),SO_2,NO_2,and CO were positively correlated with SO_2 and PM_(2.5). The average correlation coefficient of PM_(10) is around 0. 800,which was highly positively correlated,which was consistent with the time-varying trend of the concentration of pollutants from New Year's Eve to the first day.
