摘　　要：基于大连市国控站和超级站2022—2023年除夕观测数据,对比分析了烟花爆竹燃放和禁燃对大气环境的影响。研究表明:2023年燃放烟花爆竹对PM_(2.5)、PM_(10)和SO2的平均贡献量分别为430.51、585.35和47.59μg/m^(3),明显高于2022年(禁燃),禁燃管控有效降低大气污染物浓度;2023年燃放期PM_(2.5)浓度、OC浓度、EC浓度和OC/EC分别为1087、27.134、3.031μg/m^(3)和8.772,分别为2022年的32.0倍、5.7倍、3.1倍和1.7倍;2023年除夕PM_(1.0)浓度升高快、降低慢,PM_(1.0)/PM_(10)和PM_(2.5)/PM_(10)为56%和66%,烟花爆竹燃放对PM_(1.0)贡献更大。Based on the observation data from the Dalian national air quality monitoring station and the super station on the eve of the Chinese New Year in 2022 and 2023,the impact of fireworks and firecrackers on the atmospheric environment was compared and analyzed.The research results showed that the average contributions of fireworks and firecrackers to PM_(2.5),PM_(10),and SO 2 in 2023 were 430.51μg/m^(3),585.35μg/m^(3),and 47.59μg/m^(3),respectively,significantly higher than in 2022(prohibition),showing that the prohibition effectively reduces the concentration of atmospheric pollutants.During the 2023 fireworks period,the concentrations of PM_(2.5),OC,EC,and OC/EC were 1087μg/m^(3),27.134μg/m^(3),3.031μg/m^(3),and 8.772,respectively,which were 32.0 times,5.7 times,3.1 times,and 1.7 times higher than in 2022.On New Year s Eve in 2023,the concentration of PM_(1.0)rised quickly and decreased slowly,with PM_(1.0)/PM_(10)and PM_(2.5)/PM_(10)accounting for 56%and 66%,respectively.Fireworks and firecrackers had a greater contribution of to PM_(1.0).
