摘要
为了解春节期间烟花爆竹燃放对乌鲁木齐市区PM_(2.5)及其组分的影响,利用超级站在线监测仪器(包括颗粒物分析仪、在线离子色谱、激光雷达和重金属分析仪)对环境空气中的PM_(2.5)浓度、颗粒物水溶性离子和重金属浓度进行连续监测。结果表明,大量烟花爆竹的集中燃放造成了PM_(2.5)短时严重污染,最高质量浓度达到了423μg/m^(3)。烟花爆竹燃放高峰时段,SO_(4)^(2-)、Mg^(2+)、Cl^(-)、K^(+)出现了明显的浓度峰值,分别达到了129.0、0.6、14.9、38.4μg/m^(3)。重金属浓度也出现了明显的峰值,Cu、Zn、Ba、Pb质量浓度分别达到了0.158、0.036、0.402、0.086μg/m^(3)。烟花爆竹燃放已成为造成春节期间大气污染物浓度上升的重要因素,应尽量减少烟花爆竹的燃放。春节期间空气质量主要以本地污染为主。
To understand the effects of setting off firework on PM_(2.5)and its components in Urumqi city during the Spring Festival.Ambient concentrations of PM_(2.5),water-soluble ions,and heavy metals were online measured by Super Monitoring Station.The analysis results show that the concentrated discharge of a large number of fireworks has caused a short-term serious pollution of PM_(2.5),with the maximum value of 423μg/m^(3).During the peak period of fireworks discharge,SO_(4)^(2-)、Mg^(2+)、Cl^(-)、K^(+)showed obvious concentration peaks,reaching 129.0,0.6,14.9 and 38.4μg/m^(3),respectively.The peak values of heavy metals also appeared during this period,the concentration of Cu,Zn,Ba,Pb reached 0.158,0.036,0.402 and 0.086μg/m^(3).Fireworks and firecrackers have become an important factor causing the rise of the concentration of pollutants during the Spring Festival,and fireworks should be reduced as far as possible.Air quality during the Spring Festival is mainly due to local pollution.
