摘要
为探明呼和浩特市挥发性有机物(Volatile Organic Compounds,VOCs)污染特征和来源,基于呼和浩特市采样数据,通过对VOCs组分清单数据进行深入整理,构建了当地VOCs源成分谱,并利用大气污染源排放清单对排放源进行排放量分配.利用最大增量反应活性法计算臭氧生成潜势,对各主要排放源的贡献进行定量分析.结果表明,呼和浩特市VOCs排放在区域大气化学过程中具有重要影响,其中工艺过程源、移动源和溶剂使用源贡献突出;臭氧生成中,移动源贡献最高,其次是工艺过程源和溶剂使用源;分析VOCs组分清单和MIR值,确定了对臭氧生成潜势贡献最大的 20 种VOCs组分,主要来自移动源、工艺过程源和溶剂使用源.这些结果为区域大气污染综合治理提供了科学依据,对实现呼和浩特市生态环境保护目标具有重要意义.
Abstract
In order to find out the characteristics and sources of VOCs pollution in Hohhot,based on the sampling data of Hohhot,the composition spectrum of local VOCs sources was constructed by in-depth sorting out the VOCs component list data,and the emission list of air pollution sources was used to assign emissions to emission sources.The maximum incremental reactivity method was used to calculate the ozone generation potential,and the contribution of each major emission source was quantitatively analyzed.The results show that VOCs emission in Hohhot city has an important influence on regional atmospheric chemistry,and the contribution of process sources,mobile sources and solvent use sources is prominent.In ozone generation,mobile source contributed the most,followed by process source and solvent use source.By analyzing the VOCs component list and MIR values,20 VOCs components with the greatest contribution to ozone generation potential were identified,mainly from mobile sources,process sources and solvent use sources.These results provide a scientific basis for the comprehensive control of regional air pollution,and are of great significance for the realization of ecological environmental protection objectives in Hohhot.
