Air pollution modeling
Three air pollution models are presented which address themselves to the specific problems of 1) pinpointing locations of relative maxima, 2) producing air quality maps efficiently, and 3) presenting. graphic representation of patterns of pollution over a mesoscale region. MAXPOL-A is a …

Air pollution impacts to agricultural crops
Although air pollution levels are increasing, there is no knowledge of air pollution effects on agricultural crops in the Peshawar region of Pakistan. The aim of this study was to assess the impact of ozone (O3) and hydrogen fluoride (HF) on agricultural crops in Peshawar through a combination of …

Air pollution modelling over complex topography
The present study deals with air pollution modelling over complex topography, both from the phenomenological and numerical point of view. The theme of air pollution modelling has been faced at first from a phenomenological point of view. Then a numerical approach for the resolution of the …

Effects of air pollution on vascular thrombosis
Increases in air pollution, especially the particulate component, are associated with increased cardiovascular mortality, possibly through increases in thrombogenic mechanisms. The research presented in this thesis addresses the hypothesis that diesel exhaust particulates (DEP) increase …

An air pollution model for complex terrain
A dynamic air quality modeling system is presented for use in regions of complex terrain. It consists of two pre-processors and the air quality model. TERRAIN is the terrain analysis preprocessor. It accepts as input digitized terrain elevation data and analyses it in terms of the orientation and …

Modeling Outdoor Air Pollution and the Urban Form
As cities continue to grow rapidly, air pollution is becoming an increasing health problem. However, air pollution’s spatial and temporal variability make it difficult to quantify, even with field measurements. Models are thus useful to understand how pollutants interact with the built and natural …

Impact of Air Pollution on Stroke Incidence in Texas
… this thesis was to examine the relation between air pollution and stroke death rate in Texas in 1999. Air pollutants considered in this study were carbon monoxide, sulfur dioxide, nitrogen oxide, particulate matter (PM) 2.5, PM 10, volatile organic compounds and total criteria air pollutant. The …

Environmental assessment of global site-specific industrial air pollution
… an in-depth analysis of global industrial air emissions and resulting human health impacts from nearly all global fossil power plants, steel mills, oil refineries and cement plants individually. Thus, detailed inventories are developed that link the specific technologies in use at more than …

Air Pollution and Fetal Loss in the Global Tropics
<p>Abstract: Recent work has shown that in-utero air pollution has negative effects on both contemporaneous birth outcomes and long-term human capital outcomes. However, only a few studies explore the effects of in-utero exposure to air pollution on fetal loss, and none of the studies has been done …

Air pollution in Christchurch: the current state of affairs
… type smog in winter." International Union of Air Pollution Prevention Associations, 1977. This article is an attempt to fill a gap in the literature relating to air pollution in Christchurch. Most, if not all, available reports and articles give only a very brief, narrow introduction relating …

The effectiveness of local air pollution control in Lancashire
This thesis examines the implementation of air pollution control at the local level within the UK. Focusing upon the local air pollution control regime (LAPC) that is regulated by local authorities under the provisions of Part One of the Environmental Protection Act 1990, the research assesses …

Association between Air Pollution and Cancer Incidence by region
… This study investigated the relation between air pollution and cancer incidence in Korea to determine the pollutants at which incidence rates increase and to find out the influence of carcinogens on cancer incidence. METHODS: This study carried out the examination of relation between cancer …

Portable and Non-Intrusive Sensors for Monitoring Air Pollution
Air pollution is a global problem. Particulate Matter (PM) of aerodynamic diameter smaller than 2.5 μm (known as PM₂.₅) and NO₂ are important classes of pollutants because of their size and emission sources and potential effects of exposure beyond 25 μm/m³ and 40 μm/m³ annual mean respectively. …

Air pollution modelling for the greater Cape Town region
… area has been undertaken. This thesis deals with air-pollution aspects in relation to dispersion modelling, as well as with the input requirements and application of a dispersion model in the Greater Cape Town region. An EPA approved Gaussian plume model, the Industrial Source Complex Short Term 2 …

Air pollution exposure during pregnancy among rural Ugandan women
Introduction: Air pollution monitoring of hazardous pollutants such as CO (Carbon Monoxide) and PM (Particulate Matter) are important for assessing whether air pollution thresholds are not exceeded in the environment. There is sparce data that has been collected in the African region for air …

Modeling study of air pollution in the Mexico City area
The purpose of this research is to study the air pollution problem in the Mexico City (MC) area. The WRF/Chem model is used to simulate the chemical oxidants and dust aerosols, including meteorological conditions. The observations during the 2006 MILAGRO (Megacity Initiative: Local and Global …
