The meetings in this series have discussed and considered many important air pollution issues and the international nature of the attendees has ensured that the conference findings and conclusions enjoy wide and rapid dissemination amongst the air pollution science and policy communities. The series has demonstrated the widespread nature of the air pollution phenomena and has explored in depth their impacts on human health and the environment. Consequently, the series has enjoyed a wide range of high-quality papers from leading researchers that develop the fundamental science of air pollution and an equally impressive range of presentations that places these new developments within the frame of mitigation and management of air pollution. The papers selected for presentation and included in the Conference Proceedings have been permanently stored in the WIT eLibrary (see https://www.witpress.com/elibrary) from where they can be freely downloaded. These collected papers provide an invaluable record of the development of science and policy pertaining to air pollution. Objectives Air pollution issues remain among the most challenging problems facing the international community, with sources, pollutants and solutions continuously evolving. The scientific knowledge derived from well-designed studies needs to be allied with further technical and economic studies in order to ensure cost-effective and efficient mitigation. In turn, the science, technology and economic outcomes are necessary but not sufficient. Increasingly, the conference series has led to the recognition that the outcome of such research needs are multifaceted. Research needs to be contextualised within well-formulated communication strategies that help policymakers, industry and citizens to understand and appreciate the risks and rewards arising from air pollution management. Of equal importance is the need to embed non-academics in the design, development and delivery of air pollution research to ensure outcomes are as impactful and meaningful as possible.
