摘要/Abstract

摘要：

利用固相微萃取-气相色谱质谱法(SPME/GC-MS)对合肥市董铺水库监测站大气挥发性有机物（volatile organic compounds, VOCs）进行了连续检测，研究了一定时间内该地区大气VOCs的组成及变化特征。研究结果表明该地区VOCs主要由苯系物、醛酮类和烷烃构成。并用PCA/APCS（principal component analysis /absolute principal component scores）受体模型对大气中VOCs的来源进行了分析。结果表明该地区大气中VOCs主要有4个来源，分别为机动车排放源、化学试剂源、工业生产源和医用酒精挥发源，其贡献率依次为38.9%、49.48%、8.13%和3.49%。

Abstract:

Solid phase micro extraction and gas chromatography mass spectrometry (SPME/GC-MS) was used to detect the ambient volatile organic compounds (VOCs) in Hefei Dongpu Reservoir, China, and the composition and variation characteristics of VOCs in the area were investigated. The result shows that these VOCs are mainly composed of benzene series, aldehydes, ketones and alkanes. Principal component analysis /absolute principal component scores (PCA/APCS) model was used to analyze the source of the VOCs. The result shows that there are 4 main sources of the VOCs, such as automobile emission sources account for 38.9%, chemical reagents sources account for 49.48%, industrial production sources account for 8.13% and medical alcohol evaporation sources accounts for 3.49%, respectively.

Key words: volatile organic compounds, solid phase micro extraction and gas chromatography mass spectrometry, principal component analysis/absolute principal component scores, source apportionment
