Air pollution dispersion over Durban is studied using satellite, reanalysis and in situ measurements. This coastal city of 4 million people located on the east coast South Africa contributes 29 T/yr trace gases, mostly from transport industry. Terrestrial agricultural particulates derive Kalahari Desert, Zambezi Valley Mozambique. Surface air pollutants accumulate during winter (May–August) pro...

This chapter describes how estimates of air pollution emissions are transformed into ambient concentration of pollution, further translated into exposure and health impacts on a population, and finally expressed in damages. Different trade and environmental policy menus lead to different levels of pollution emissions and income. For each menu the emissions levels translate into specific mortali...

In the case of a major pollution incident, terrorist attack, or a radioactive event such as the Chernobyl disaster in 1986, dispersion models are used to predict the transport of pollution away from its source, so allowing potentially affected areas to be warned or even evacuated. Thus it is important for both economic and human health reasons that there is continued research in developing and ...

High quality air pollution dispersion modelling over complex terrain using Lagrangian particle model consumes a lot of computational time. In this study has been determined that there are some air pollution situations where unnecessary computational time is spent like accumulation of air pollution in the domain during the calm or extra high emissions from sources due to temporary failure of exh...

OBJECTIVE To model the possible air pollution-related health impact of the 2005 oil depot fire at Buncefield, near London, UK, under alternative meteorological conditions to those experienced at the time. DESIGN Atmospheric dispersion modelling of the smoke plume was conducted under the range of meteorological conditions occurring throughout 2005 assuming constant particle emission rates. Pop...

Journey-time exposures represent an important, though as yet little-studied, component of human exposure to traffic-related air pollution, potentially with important health effects. Methods for assessing journey-time exposures, either as part of epidemiological studies or for policy assessment, are, however, poorly developed. This paper describes the development and testing of a GIS-based syste...

Mesoscale air quality under stagnant synoptic cold season conditions in the Lake Powell area is characterized through climatological, topographical and numerical studies. Using a synoptic climatological classification scheme, it is found that during the winter this region is dominated by stagnant conditions associated with slow-moving high pressure systems. Using topographic analyses, the Lake ...
