化石燃料发电厂排放的二氧化硫和二氧化氮会转化为硫酸和硝酸并随后沉积，从而产生严重的环境后果。因此，人们对能够监测这些排放的技术非常感兴趣，以确保遵守环境法规。在这里，我们提出了一种测量电站 SO2 和 NO2 排放的新方法，通过汽车或步行在羽流下方移动，或者使用紧凑、轻便的紫外光谱仪从固定位置扫描电站的羽流。这项工作于 2003 年 1 月、2 月和 6 月在英格兰东部的一个发电站进行，结果 SO2 通量为 5.2 kg·s(-1)，与堆内测量值 5.3 kg·s(-1) 密切对应。与监测这些排放的其他遥感方法相比，该技术要简单得多且便宜得多。 (C) 2003 Elsevier Ltd. 保留所有权利。
Emissions of SO2 and NO2 from fossil fuel power stations can have serious environmental consequences via conversion to sulphuric and nitric acids and subsequent deposition. Consequently, there is considerable interest in techniques capable of monitoring these emissions, in order to ensure compliance with environmental legislation. Here we present a novel approach to measuring power station SO2 and NO2 emissions by traversing underneath the plume by car or on-foot or scanning the power station's plume from a fixed position with a compact and lightweight UV spectrometer. This work was performed at a power station in eastern England during January, February and June 2003, resulting in a SO2 flux of 5.2 kg s(-1), which is in close correspondence with the in-stack measured value of 5.3 kg s(-1). This technique is considerably simpler and cheaper than other remote sensing approaches to monitoring these emissions. (C) 2003 Elsevier Ltd. All rights reserved.
