Peter H. McMurry is the Kenneth T. Whitby Professor of Mechanical Engineering at the University of Minnesota, where he has served as Department Head since 1977. He is a past President of the American Association for Aerosol Research. His research focuses on phenomena including nucleation, growth, water uptake, and light scattering. With his research colleagues he has developed a condensation nucleus counter to detect particles as small as 3 nm, aerodynamic lenses to produce tightly collimated particle beams, and instruments to measure particle properties that include density, refractive index, and water content. He has written recent review articles on atmospheric aerosol measurement and nucleation. Marjorie F. Shepherd is Senior Science Advisor at the Atmospheric and Climate Science Directorate, Meteorological Service of Canada. Her work involves investigating sampling and analysis methodologies for ambient volatile organic compounds. She has coordinated several projects within the Canadian multi-stakeholder science assessment for ground-level ozone. As science advisor for the Meteorological Service of Canada, she co-lead, with Health Canada, the development of science assessments for HF, CO, ozone and particulate matter – all in support of developing Canadian air quality objectives and standards. James S. Vickery is one of the founding members of NARSTO and a member of the Executive Steering Committee. He is a Co-Leader of the US Committee on Environment and Natural Resources - Particulate Matter Research Work Group, which coordinates all U.S. Federally sponsored research concerning particulate matter. He is Special Assistant to the Director of EPA's National Exposure Research Laboratory, where he has also held the positions of Division Director and Assistant Laboratory Director. He has also managed several different program and policy offices in EPA's Washington, DC headquarters.

'… concise and comprehensive discussion of the current understanding of airborne particulate matter … The technical quality of the book is very good. A lot of flow diagrams, schemes, tables, figures and images support the information content … It is really necessary as information source for each policy maker but also for each library of research institutes.'
