Air pollution from diesel emissions is becoming an increased international concern, and whilst attention has been primarily focused on the automotive industry, concerns have also been raised about emissions from diesel rail vehicles. This paper reports an extensive series of measurements made at the Birmingham New Street station, a major rail interchange in the Midlands of England, with a mix of diesel and electric train movements, which is of particular concern because of the enclosed nature of the platforms. This study was undertaken in collaboration with Network Rail to better understand the environment in and around the station over a longer period to provide a more detailed analysis of the complex environment at the station. The station environment has been considered in terms of the European Union (EU) and Department of Environment, Food and Rural Affairs (DEFRA) limits as part of the monitoring methodology, but it should be noted that these limits do not apply in this environment as the Management of Health and Safety at Work Regulation 1999 and the Control of Substances Hazardous to Health Regulations 2002 are applicable. The monitoring campaign consisted of diffusion tube measurements to measure nitrogen dioxide at a large number of different locations throughout and around the station. These were followed by detailed measurements of oxides of nitrogen, particulate matter, carbon dioxide and black carbon (a diesel tracer) at a smaller number of sites at the platform level. The results are analysed to give concentrations over a wide variety of time scales, and long- and short-term averages. The effects of ambient wind conditions and individual train movements are also considered. Recommendations are made for possible remedial measures and for future work to more fully understand the physical mechanisms involved.

伯明翰新街火车站空气质量评价

柴油排放造成的空气污染日益受到国际社会的关注，虽然人们的注意力主要集中在汽车行业，但柴油轨道车辆的排放也引起了人们的担忧。本文报告了在伯明翰新街车站进行的一系列广泛测量，伯明翰新街车站是英格兰中部地区的一个主要铁路交汇处，混合了柴油和电力列车运行，由于站台的封闭性，这一点特别令人关注。这项研究是与 Network Rail 合作进行的，旨在更长期地了解车站及其周围的环境，从而对车站的复杂环境进行更详细的分析。作为监测方法的一部分，已根据欧盟 (EU) 和环境、食品和农村事务部 (DEFRA) 的限制考虑了监测站环境，但应注意的是，这些限制不适用于此环境，因为适用《1999 年工作健康与安全管理条例》和《2002 年有害健康物质控制条例》。监测活动包括扩散管测量，以测量空间站及其周围许多不同位置的二氧化氮。随后，在平台层面的少量地点对氮氧化物、颗粒物、二氧化碳和黑碳（柴油示踪剂）进行了详细测量。对结果进行分析，得出各种时间范围内的浓度以及长期和短期平均值。还考虑了环境风力条件和个别列车运行的影响。提出了可能的补救措施和未来工作的建议，以更全面地了解所涉及的物理机制。
