My research is based within the general field of air quality. This work started with air pollution surveying as part of environmental impact statements for UK airports. Through 30 years of making high quality measurements, my focus has been upon volatile organic compounds (VOC), in particular benzene. From my Ph.D. “The Sources and Behavior of Selected Urban Air Pollutants” my data, including the last significant “pea soup” smog event in London, was used to define new ambient air quality standards for benzene and 1,3-butadine in the UK, my research extended to helping to build a national network while developing novel data validation procedures that used AI for chromatographic analysis. The UK standard for benzene was later adopted by the rest of the European Union. My VOC research has paid particular attention to instrument development, method standardization and wintertime ozone. At present my work has three focus areas: 1.) Methane and VOC emissions from energy development, in collaboration with Shane Murphy; 2.) Long term background air quality monitoring; and 3.) Diffusive sampling development in collaboration with the European Union. My research goals are to support the wider community with developing methods and strategies for high quality measurements and analysis to support both regulatory work and emerging air quality issues. This is driven by a concern for the impacts of air pollution upon health and quality of life.
