OBJECTIVE In this retrospective cohort (1998 to 2007), 145,445 singleton live births in Hillsborough, Florida, were analyzed to elucidate the relationship between fetal morbidity and prenatal exposure to six criteria air pollutants. METHODS This study was based on three linked databases: Florida Hospital Discharge, vital statistics records, and air pollution meteorological data from the Envir...

A new method for multi-objective optimization of air quality monitoring systems based on satellite remote sensing of the troposphere is described in this work. The technique uses atmospheric turbidity as surrogate for air pollution loading. Through inverse chemical modeling and ancillary information the respective patterns of primary gaseous and particle pollutants are inferred. The optimizatio...

This study presents the application of multi-criteria evaluation in the selection of an optimal configuration for an Air Quality Model. The simulation domains focus on the Mexico City Metropolitan Area. A set of 10 different configurations were considered as alternatives. These configurations included convective parameterization, 6th order diffusion and exclusion of data assimilation within the...

The urban environment is where an increasing share of the world’s population resides, where the most commercial energy is consumed, and where the impacts of pollution are imposed the most. In the urban environment, because of its complex structure, the air pollution appears unpredictable covering narrow area. The AirScope system is developed for that kind of micro-scale air pollution management...

The present study applies the model of American Meteorological Society-Environmental Protection Agency Regulatory Model (AERMOD) to investigate NO2 emissions from Besat thermal power plant, which is fuelled by natural gas to function. Results indicate that the simulated concentration of NO2 based on AERMOD, does not exceed NO2 concentration limit, set by the Iranian Ambient Air Quality Standard...

Atmospheric contamination has deteriorated the health of plants and animals all over the globe. In particular, pollutants such as benzene(C6H6) has accelerated the rate of cancer among human beings. Therefore, accurate evaluation of the pollutant in the atmosphere is necessary by traffic supervision in urban areas. To reduce atmospheric contamination, an effective mobile strategy planning must ...

The inter-comparison of regional air quality models is an effective way to understand uncertainty in ambient pollutant concentrations simulated using various model configurations, as well as to find ways to improve model performance. Based on the outcomes and experiences of Japanese projects thus far, a new model inter-comparison project called Japan’s study for reference air quality modeling (...

Indoor air pollution, specifically restricted in its meaning to chemicals in home indoor air environment, presents a new and probably an important challenge to the researchers of the air pollution field. The general overview of this topic suggests that the voluminous data generated in the past ten or so years have only defined the rudiments of the problem, and significant areas of research stil...
