摘要
为研究铜陵市环境空气中颗粒物污染的特征,以铜陵市 2023 年 12 月出现的一次细颗粒物污染过程为研究对象,采用污染过程期间铜陵市环境空气质量监测数据和大气颗粒物组分监测数据进行分析.污染过程中,颗粒物经历累积、较重、清除 3 个阶段,污染来源主要为二次转化源.污染时段在冬季,污染传输、扩散条件差及本地污染累积是此次污染过程出现的主要原因.
Abstract
In order to study the characteristics of particulate matter pollution in the ambient air of Tongling city,a fine particulate matter pollution process occurred in December 2023 in Tongling city as the research object.The environmental air quality monitoring data and atmospheric particulate matter composition monitoring data during the pollution process were used for analysis.During the pollution process,particulate matter undergoes three stages:accumulation,heaviness,and removal,with the main source of pollution being secondary transformation sources.The pollution period is in winter,and poor conditions for pollution transmission and diffusion,as well as local pollution accumulation,are the main reasons for the occurrence of this pollution process.
