摘　　要：VOCs是具有代表性的大气环境挥发性有机物,所以以VOCs为例,研究大气环境中的挥发性有机物污染特征提取方法。根据山东威海工业园区环境信访分布图分析VOCs来源。以气相色谱质谱联用法为基础,通过设定采样时间、仪器、试剂,提取该园区大气环境VOCs中的污染特征。通过分析VOCs污染特征浓度的时间变化规律、不同管控措施下的变化情况、污染特征监测对比,验证了该方法能够精准快速提取大气环境挥发性有机物污染特征,具有较好的实际应用价值。VOCs are representative volatile organic compounds in the atmospheric environment.Taking VOCs as an example,this study investigates the extraction method of volatile organic compound pollution characteristics in the atmospheric environment.It analyzes the sources of VOCs based on the distribution map of environmental petitions in Weihai Industrial Park,Shandong.Based on gas chromatography-mass spectrometry,pollution characteristics of VOCs in the atmospheric environment of the park are extracted by setting sampling time,instruments,and reagents.By analyzing the temporal variation pattern of VOCs pollution characteristic concentrations,the changes under different control measures,and comparing pollution characteristic monitoring,it has been verified that this method can accurately and quickly extract the characteristics of volatile organic compound pollution in the atmospheric environment,and has good practical application value.
