在2016年的时候，第一卷。71，没有。2（每小时浓度），世界卫生组织NO2安全暴露限值104.6ppb（约200μg/m3;世界卫生组织，2014年）仅因发电站排放而很少超过。他们认为，超过世界卫生组织NO2限值的风险很低，只有在发电站NOx羽流与极端臭氧事件同时发生的情况下才有可能。在英国的约克郡，有三个大型发电站：Drax，Eggborough和Ferrybridge。它们的发电能力分别为3960兆瓦（Drax，2014），2000兆瓦（Eggborough Power Limited，2014）和980兆瓦（SSE，2014）。图1（a）显示了2005年至2011年期间臭氧监测仪器（OMI）提供的英国对流层NO2柱平均值。峰值浓度呼吸和心血管问题。NO2可导致肺功能下降，PM可导致死亡率和发病率增加（WHO，2014）。发电厂排放的废气（特别是NO2、SO2和PM）会对区域和当地的空气质量产生重大影响。在北京，Hao等人（2007年）估计，发电站排放的SO2、NOx（NO + NO2）和PM10分别占城市排放量的49%、27%和11%。Mauzerall等人（2005年）表明，较大点源（如发电站）的氮氧化物排放可显著影响源下风处的表面O3浓度，这可能对人口密集地区的人类健康有害。Webb和Hunter（1998）发现，1992年至1996年间，短期内Richard Pope 1，2和Miroslav Provod 11利兹大学地球与环境学院2利兹大学国家地球观测中心（NCEO）
W ea th er – F eb ru ar y 20 16 , V ol . 7 1, N o. 2 (hourly concentrations), the WHO NO2 safe exposure limit of 104.6ppb (approximately 200μg/m3; WHO, 2014) was rarely exceeded as a result of power station emissions alone. They suggested that the risk of exceeding the WHO NO2 limit was low and only likely in the case of a power station NOx plume coinciding with an extreme ozone event. In Yorkshire, UK, there are three large power stations: Drax, Eggborough and Ferrybridge. They have generating capacities of 3960MW (Drax, 2014), 2000MW (Eggborough Power Limited, 2014) and 980MW (SSE, 2014), respectively. Figure 1(a) shows average UK tropospheric column NO2 from the Ozone Monitoring Instrument (OMI) between 2005 and 2011. The peak concentrations breathing and cardiovascular problems. NO2 can cause reduced lung function and PM can lead to increased mortality and morbidity (WHO, 2014). Power station emissions (particularly NO2, SO2 and PM) can have a significant impact on regional and local air quality. In Beijing, Hao et al. (2007) estimate that power stations emit 49, 27 and 11% of city SO2, NOx (NO + NO2) and PM10, respectively. Mauzerall et al. (2005) show that emissions of NOx from larger point sources (e.g. power stations) can significantly influence surface O3 concentrations leeward of the source, which can be detrimental to human health in populated regions. Webb and Hunter (1998) found that between 1992 and 1996, in the short-term Richard Pope1,2 and Miroslav Provod1 1School of Earth and Environment, University of Leeds 2National Centre for Earth Observation (NCEO), Univ ersity of Leeds
