削减VOCs对保证齐齐哈尔市环境空气质量约束性指标完成的意义及途径

The Significance and Ways of Reducing VOCs and Fulfilling Constraint Index of Ambient Air Quality in Qiqihar City

挥发性有机物(VOCs)作为一种特征污染物,在《环境空气质量标准》中只有苯并(a)芘一项。但在实际监测工作中,涉及的有机污染物种类在不断增多,VOCs污染防治相对滞后。首次提出开展VOCs的控制问题是"十二五",国内外研究表明作为前体物的VOCs对PM2.5形成起着重要作用。近五年齐齐哈尔市环境空气质量超标因子主要是PM2.5,削减VOCs排放,对降低PM2.5浓度,实现"十三五"期间环境空气质量约束性指标完成,具有重要的意义。

Volatile organic compounds(VOCs) as a kind of characteristic pollutants, have only one index of benzo(a) pyrene in Ambient Air Quality Standard. However, in actual monitoring work, the types of organic pollutants involved are increasing, and the prevention and control of VOCs pollution is relatively lagging behind.Pollution control of VOCs began in the 12 th five-year-plan. Studies at home and abroad have shown that VOCs,as precursor, plays an important role in the formation of PM2.5. In the past five years PM2.5 was the main index that exceeded Ambient Air Quality Standard in Qiqihar city. Reducing VOCs emission has important significance for fulfilling constraint index of Ambient Air Quality in Qiqihar city.
