摘要

摘要: 使用道路抑尘剂对北京市丰台区看丹桥附近区域进行了道路抑尘处理，总共喷洒路面40万m²，在喷洒路面及对照路面分别设置了采样点，监测喷洒前后空气中PM_2.5、PM₁₀、NO_x浓度情况，并对收集的颗粒物中水溶性阴离子成分和元素成分进行了分析。结果表明，通过喷洒道路抑尘剂可以在一定范围内改善大气污染状况，其对PM₁₀的控制作用最为明显，PM₁₀去除率达到25.0%；PM^_2.5次之，去除率为12.0%；对NO_x则在短期内较为有效，去除率为20.1%。道路抑尘剂也能对大气中的某些特定阴离子成分及无机元素成分具有较好的控制作用。

Abstract: The road dust suppressant was used to reduce the dust in the air at Kandan Bridge, Fengtai District in Beijing. The sprayed area was 0.4 million square meters. Sampling points were set both at sprayed area and non-sprayed area to monitor change of PM_2.5, PM₁₀, NO_x concentrations before and after the spraying, and the water-soluble anions and elements collected in the particulates analyzed. The results showed that the air pollution situation was improved by the way of spraying dust suppressant. PM₁₀ was reduced significantly, the restrain rate is 25.0%. PM_2.5 took the second, the restrain rate is 12.0%, and NO_x was controlled only in a short term, the rate is 20.1%. In addition, the dust suppressant was efficient for controlling certain specific anions and inorganic elements in the air.
