It has long been known that air pollution is harmful to human health, as many epidemiological studies have been conducted into its effects. Collectively, these studies have investigated both the acute and chronic effects of pollution, with the latter typically based on individual level cohort designs that can be expensive to implement. As a result of the increasing availability of small-area st...

Buildings represent a major part of the world energy requirement. The simulation of combined heat, air and moisture (HAM) and pollutant transfer in this context is important to predict the indoor air quality (IAQ), along with the thermal comfort inside the buildings. Moreover, it is important to have appropriate levels of indoor humidity along with the room temperature as movement of water vapo...

A modeling framework was proposed to investigate the impact of trans-boundary air pollutant transport on regional air quality. This was based on a combination of the HYSPLIT trajectory model, the CAMx air quality model, and the MM5 meteorological model. The examination of atmospheric PM10 pollution in Guangzhou within the Pearl River Delta (PRD) region of southern China was used as a case study...

The momentary maximum concentration of the most important air pollutants (nitrogen oxide, sulfur dioxide, carbon monoxide and dusts) was determined using the dispersion curves of the pollutants in the densely inhabited areas of Dâmboviţa County. In order to present the industry-wide potential impact of air pollutants on the population and on the environment, maps showing air pollution levels ha...

Polluted air contains a complex mixture of particles with a range of physical and chemical properties, gases, bioareosols and toxic substances. Estimation of how simultaneous exposure to multi-pollutants affects the risk of adverse health response represents a challenge for scientific research and air quality management. In this work we consider the problem of modelling these multi-pollutant sy...

Communication of the complex relationship between air pollutant exposure and ill health is essential to an air pollution information system. We propose a novel air pollution index (API) system based on the relative risk of the well-established increased daily mortality associated with short-term exposure to common air pollutants: particulate matter (PM10, PM2.5), sulphur dioxide, ozone, nitroge...

Understanding local-scale transport and dispersion of pollutants emitted from traffic sources is important for urban planning and air quality assessments. Predicting pollutant concentration patterns in complex environments depends on accurate representations of local features (e.g., noise barriers, trees, buildings) affecting near-field air flows. This study examined the effects of roadside bar...

BACKGROUND Numerous earlier studies examining the association of air pollution with maternal and foetal health estimated maternal exposure to air pollutants based on the women's residential addresses. However, residential addresses, which are personally identifiable information, are not always obtainable. Since a majority of pregnant women reside near their delivery hospitals, the concentration...

The expressway was dismantled in Seoul in July, 2003, and the municipal river was restored in October, 2005. In this study, it is intended that the atmospheric pollutant data and the air temperature data are accumulated in the proof of the relaxation effect of the heat island phenomenon in Cheongecheon. As a method of researching the atmospheric pollutant, the astronomical telescope was used. F...
