We report on the research conducted by the Community Action Against Asthma (CAAA) in Detroit, Michigan, to evaluate personal and community-level exposures to particulate matter (PM) among children with asthma living in an urban environment. CAAA is a community-based participatory research collaboration among academia, health agencies, and community-based organizations. CAAA investigates the eff...

Recently, attention has focused on whether particulate air pollution is a specific trigger of myocardial infarction (MI). The results of several studies of single locations assessing the effects of ambient particular matter on the risk of MI have been disparate. We used a multicity case-crossover study to examine risk of emergency hospitalization associated with fine particulate matter (PM) wit...

BACKGROUND Epidemiologic studies indirectly suggest that the inhalation of carbonaceous particulate matter impairs lung function in children. Using the carbon content of airway macrophages as a marker of individual exposure to particulate matter derived from fossil fuel, we sought direct evidence of this association. METHODS Airway macrophages were obtained from healthy children through sputu...

Geographic information system (GIS) based emission inventory of particulate matter of aerodynamic diameter less than 10 μm (PM10) for the base, 5 th and 10 th year was developed for Kanpur, an urban area in India. It has been observed that the 5 th and 10 th year will experience increased emission by factors of 1.5 and 2.2 of the base year. Twenty one control options (e.g. introduction of Euro ...

BACKGROUND Air pollution in cities has been linked to increased rates of mortality and morbidity in developed and developing countries. Although these findings have helped lead to a tightening of air-quality standards, their validity with respect to public health has been questioned. METHODS We assessed the effects of five major outdoor-air pollutants on daily mortality rates in 20 of the lar...

background: considering health and public health risks, particulate matters are the main pollutants of air and are associated with high rates of mortality and morbidity in long and short term exposures. hence, the present study was performed with the aim of estimating the health impacts attributable to pm10 in the 7 cities of mashhad, tabriz, isfahan, shiraz, arak, ahwaz, and urmia (iran) durin...

With the increasing awareness of the health impacts of particulate matter, there is a growing need to comprehend the spatial and temporal variations of the global abundance of ground level airborne particulate matter with a diameter of 2.5 microns or less (PM2.5). Here we use a suite of remote sensing and meteorological data products together with ground-based observations of particulate matter...

The paper describes a MAS (multi-agent system) simulation approach for controlling PM10 (Particulate Matter) crisis peaks. A dispersion model is used with an Artificial Neural Network (ANN) to predict the PM10 concentration level. The dispersion and ANN models are integrated into a MAS system. PM10 source controllers are modelled as software agents. The MAS is composed of agents that cooperate ...

The health implications of atmospheric particulate matter have become a topic of much interest on both sides of the Atlantic, but especially in the USA, where they were at the centre of the debate over the Environmental Protection Agency's (EPA) revision of the National Ambient Air Quality Standard in 1997. Much of this debate revolves around claims that particulate matter (usually represented ...

BACKGROUND Particulate matter and proximity to large roadways may promote disease mechanisms, including systemic inflammation, hormonal alteration, and vascular proliferation, that may contribute to the development and severity of endometriosis. OBJECTIVE Our goal was to determine the association of air pollution exposures during adulthood, including distance to road, particulate matter<2.5 μ...
