In 1969 the North Atlantic Treaty Organisation (NATO) established the Committee on Challenges of Modern Society (CCMS). The subject of air pol- tion was from the start, one of the priority problems under study within the fra- work of various pilot studies undertaken by this committee. The organization of a periodic conference dealing with air pollution modeling and its application has become one of the main activities within the pilot study relating to air pollution. The first five international conferences were organized by the United States as the pilot country; the second five by the Federal Republic of Germany; the third five by Belgium; the next four by The Netherlands; and the next five by Denmark; and with this one, the last three by Portugal. th This volume contains the papers and posters presented at the 27 NATO/CCMS International Technical Meeting on Air Pollution Modeling and Its Application held in Banff, Canada, 24-29 October 2004. The key topics at this ITM included: Role of Atmospheric Models in Air Pollution Policy and Abatement Strategies; Integrated Regional Modeling; Effects of Climate Change on Air Quality; Aerosols as Atmospheric Contaminants; New Developments; and Model Assessment and Verification. 104 participants from North and South America, Europe, Africa and Asia attended th the 27 ITM. The conference was jointly organized by the University of Aveiro, Portugal (Pilot Country) and by The University of Calgary, Canada (Host Country). A total of 74 oral and 22 poster papers were presented during the conference.

Air quality is a high priority research area of the United States Environmental Protection Agency (EPA) and research on the changing spatiotemporal patterns of PM2.5 is part of the EPA's current focus. The EPA is looking for studies on the relationship between long-term exposure to PM2.5 and cardiovascular health in order to to reduce the uncertainty of the concentration - response relationships, especially at low ambient concentration of PM2.5. A comprehensive analysis of a large volume of available PM2.5 data collected at four different regions in Wisconsin was performed to study the spatialtemporal variations, the patterns of the variations and the changes in patterns of ambient PM2.5. A systematic approach was established in the study that enables utilizing the broadely available PM2.5 data for future health research. Spatial and temporal variations of the characteristics and the changes of the discovered patterns of ambient PM2.5 and the aerosol acidity of PM2.5 were studied using statistical and graphical software. The changes in the concentrations of ambient sulfate, nitrate and OC highlight the need for changing PM2.5 reduction strategies. A change in the ambient aerosol acidity trend was observed around 2009 and 2010. P value analysis indicated both the downward and upward trends were not insignificant. A further study to determine if there is a permanent increasing trend is recommended. An ascending trend of aerosol acidity was discovered during winter episodes in Milwaukee from 2002 to 2009, which also needs additional study. A thermodynamic principle-based method was developed using the deliquescent relative humidity (DRH) as a criterion to determine if the inorganic ions in PM2.5 were in aqueous phase. If the relative humidity (RH) on the sampling day was higher than the DRH of the aerosol system, the inorganic ions were in aqueous phase and were selected for modeling. The Extended Aerosol Inorganic Model (EAIM) was used to estimate the in-situ acidity. The calculated in-situ acidity has reasonable correlation with other aerosol acidity indexes used in the study. Pattern changes in ambient PM2.5 were observed. The periods when trends change direction provide valuable opportunities to study the underlying causes of the changes.

Traffic-Related Air Pollution synthesizes and maps TRAP and its impact on human health at the individual and population level. The book analyzes mitigating standards and regulations with a focus on cities. It provides the methods and tools for assessing and quantifying the associated road traffic emissions, air pollution, exposure and population-based health impacts, while also illuminating the mechanisms underlying health impacts through clinical and toxicological research. Real-world implications are set alongside policy options, emerging technologies and best practices. Finally, the book recommends ways to influence discourse and policy to better account for the health impacts of TRAP and its societal costs. Overviews existing and emerging tools to assess TRAP’s public health impacts Examines TRAP’s health effects at the population level Explores the latest technologies and policies--alongside their potential effectiveness and adverse consequences--for mitigating TRAP Guides on how methods and tools can leverage teaching, practice and policymaking to ameliorate TRAP and its effects
