摘要
通过研究某市城区4—9月臭氧污染较严重时间段71种挥发性有机物的手工监测数据和臭氧浓度自动监测数据,分析了该市挥发性有机物在典型时段的污染特征及其与臭氧浓度变化的相关性。为该市通过控制挥发性有机物排放来精准防控臭氧污染提供参考。研究结果显示:该市挥发性有机物浓度水平与活性水平变化趋势总体一致,污染物种类在不同时间段的浓度和活性有差异,从浓度和活性角度分析得到的关键物种在不同时间段有差异,挥发性有机物的污染变化与臭氧浓度变化的相关性有时显著,有时不显著。
According to the analysis about manual monitoring data of 71 kinds of volatile organic compounds and automatic monitoring data of ozone during the period from April to September when the ozone pollution is serious in a city,the pollution characteristics of volatile organic compounds and its correlation with the change of ozone concentration in this typical period were analyzed,to give suggestions about how to precisely control ozone pollution according to the control of the VOCs discharge.The results showed that the concentration and activity of volatile organic compounds in the city were basically consistent with the overall variation trend.There were differences in the types of specific pollutants in different time periods.The key species were different in the analysis result of concentration dimension and activity dimension.The correlation between VOCs and ozone concentration sometimes was significant and sometimes was not so significant.
