摘要
2022年 6月—2023 年5 月在渭南市师范学院挥发性有机物组分站获得醛酮类项目的监测数据,围绕渭南市醛酮类化合物的浓度水平、组成特征、变化趋势进行探究,用PMF模型识别和量化出醛酮类化合物在臭氧前体物中的贡献.对识别出的组份进行排序并逐一分析高组分物质的主要来源,找到污染源头,为VOCs污染减排提供相关科学技术支持.
Abstract
Monitoring data of aldehydes and ketones were obtained from the volatile organic compound sub station of Weinan Normal University from June 2022 to May 2023.The concentration levels,composition characteristics,and trends of aldehydes and ketones in Weinan City were explored,and the contribution of aldehydes and ketones in ozone precursors was identified and quantified using the PMF model.Sort the identified components and analyze the main sources of high component substances one by one,identify the pollution source,and provide relevant scientific and technological support for VOCs pollution reduction.
