摘要
利用浏阳市2018年烟花爆竹试燃放时段污染天气作为研究背景,选取浏阳市环境空气自动监测省控站点2018年全年期间周1至周5实时监测数据及气象参数进行了分析。结果表明:烟花爆竹试燃放时段对环境空气中PM 10和PM 2.5影响显著,集中试燃放对PM 10和PM 2.5的小时值增长倍数贡献明显,烟花爆竹试燃放时段对PM 10和PM 2.5的小时值最大贡献量分别为17~31μg/m^3和11~19μg/m^3;最大增高倍数分别为0.4~0.7倍和0.4~0.9倍。PM 10和PM 2.5小时浓度均为秋季增幅最大。
Using the polluted weather during the period of fireworks test-firing in Liuyang City in 2018 as the research background, the real-time monitoring data and meteorological parameters from Monday to Friday during January 2018 to December 31 2018 at the provincial control station of Liuyang City for automatic monitoring of ambient air were analyzed. The results show that the test-release period of fireworks has a significant impact on PM10 and PM2.5 in the ambient air. Concentrated test-release has a significant contribution to the increase of hourly value of PM10 and PM2.5. The maximum contribution of the test-release period of fireworks to the hourly value of PM10 and PM2.5 is 17-31 ug/m3 and 11-19 ug/m3, respectively, and the maximum increase factor is 0.4-0.7 times and 0.4-0.9 times, respectively. The concentration of PM10 and PM2.5 hours increased the most in autumn.
