除夕夜烟花爆竹燃放对重庆市空气质量的影响

摘要

Based on the monitoring data during the Spring Festival in 2010 -2014 in Chongqing urban area , the impact of setting off fireworks and firecracker to the air quality was analyzed.Results showed that particle concentration appeared high peak in a short time when a large number of fireworks were fired.The pollutants displayed cumulative effect and the maximum concentration generally appeared in the new moon at about 3:00 in the morning.The fireworks had a significant impact to the particle concentration , followed by SO 2 , and had minimum effect on the NO 2.%利用重庆市主城区2010-2014年春节期间监测数据，分析了燃放烟花爆竹对环境空气质量的影响。结果表明：大量燃放烟花爆竹集中时段，颗粒物浓度会在短时间内出现极高峰值，一般出现在初一凌晨3时左右，显示出一定累积效应；污染物中受烟花爆竹影响程度较大的是颗粒物，其次为SO2， NO2受影响程度相对最小。
