| 中文摘要: |
| 利用镇江市2019年4—10月市区4个空气质量国控站点VOCs监测数据，对大气中70种VOCs的组分特征、时间与区域变化进行分析，并用比值法研究VOCs来源特征。结果表明，4个站点PAMS组分的测定值为17.7 μg/m3~27.5μg/m3，醛酮类组分为15.4 μg/m3~165 μg/m3。各站点VOCs来源侧重点略有不同，主要来源是工业源、交通源、溶剂涂料的使用等。 |
| 英文摘要: |
| Based on the monitoring data of 70 VOCs at 4 national air quality control stations in Zhenjiang from April to October in 2019, the composition characteristics, temporal and spatial variation of concentration were analyzed. The source of VOCs was studied by ratio method. The results showed that the concentration of PAMS at each station ranged from 17.7 μg/m3 to 27.5 μg/m3, the concentration of aldehydes and ketones ranged from 15.4 μg/m3 to 165 μg/m3. The source of VOCs at each station was different. The main sources were from industry, transportation and solvent coating. |
