摘要
研究环境空气中挥发性有机污染物特征,为城市环境治理提供科学数据依据。以某省为研究对象,使用恒流采样方式采集该省4个季节的空气样本。通过硅烷化苏玛罐—大气浓缩仪—气相色谱—质谱法的方法对采集到的空气样本进行挥发性有机污染物的检测分析。分析结果表明,该省环境空气中常规挥发性有机污染物污染因子主要为PM2.5、PM10和SO2等,且该省冬季和秋季常规挥发性有机污染物污染因子浓度均超过国家规定数值,冬季空气有机物污染较为严重;该省环境空气中挥发性有机污染物单体污染物有36种,包括烷烃、烯烃、炔烃、芳香烃和卤代烃,其中烷烃、烯烃、炔烃和芳香烃为该省环境空气内的主要有机污染物;5种挥发性有机污染物受环境温度、湿度和风速影响较大,且其主要成分浓度分布具备季节性特征。
Study the characteristics of volatile organic pollutants in the ambient air to provide scientific data for urban environmental governance.Taking a province as the research object,the air samples of four seasons in the province are collected by constant current sampling.The volatile organic pollutants in the collected air samples are detected and analyzed by the method of silanization suma tank air concentrator gas chromatography mass spectrometry.The analysis results show that the pollution factors of conventional volatile organic pollutants in the ambient air of the province are mainly PM2.5,PM10 and SO2,and the concentration of conventional volatile organic pollutants in the winter and autumn of the province exceeds the national value,and the air organic pollution is relatively serious in winter.There are 36 kinds of volatile organic pollutants in the ambient air of the province,including alkanes,olefins,alkynes,aromatic hydrocarbons and halogenated hydrocarbons,among which alkanes,olefins,alkynes and aromatic hydrocarbons are the main organic pollutants in the ambient air of the province.The five volatile organic pollutants are greatly affected by ambient temperature,humidity and wind speed,and the concentration distribution of their main components has seasonal characteristics.
