| 中文摘要: |
| 基于臭氧（O3）及前体物监测数据，综合运用正定矩阵因子分解模型（PMF）、O3生成敏感性（EKMA）曲线、O3来源解析工具（OSAT）等方法，对苏州工业园区2022年春季一次典型O3污染过程成因开展研究。结果表明，高温及前体物的累积是导致园区O3超标的主要成因，个别污染时段O3及前体物受浙江、上海传输影响；污染期间园区处于典型VOCs控制区，VOCs主要来源为油气储运（35.6%）、区域背景（28.8%）、塑料制品生产（16.0%）、移动源（13.6%）、溶剂使用（6.0%）。为有效削减不利气象条件下O3峰值浓度，应重点加强本地溶剂使用、油品挥发、有机合成等污染环节VOCs的管控。 |
| 英文摘要: |
| Based on the monitoring data of ozone(O3) and its precursors， positive matrix factorization model(PMF)， O3 generation sensitivity（EKMA） curve and O3 source analysis tool(OSAT) were comprehensively used to study the causes of a typical O3 pollution event in Suzhou Industrial Park in the spring of 2022. The results showed that high temperature and accumulation of precursors were the main causes of O3 exceeding the standard in the park. Individual periods of pollution were affected by the transport of O3 and its precursors from Zhejiang and Shanghai. During the pollution period， the park was in a typical VOCs control area. The main sources of VOCs were oil and gas storage and transportation(35.6%)，regional background(28.8%)， plastic product production(16.0%)， mobile sources(13.6%) and solvent use(6.0%).It should focus on strengthening the control of VOCs in local solvent use， oil volatilization， organic synthesis and other pollution links to effectively reduce the peak O3 concentration under adverse meteorological conditions. |
