In this article I introduce an alternative method for estimating particulate air pollution mortality concentration-response functions. This method constrains the particulate air pollution mortality concentration-response function to be biologically plausible--that is, a non-decreasing function of the particulate air pollution concentration. Using time-series data from Cook County, Illinois, the...

Numerous studies have observed health effects of particulate air pollution. Compared to early studies that focused on severe air pollution episodes, recent studies are more relevant to understanding health effects of pollution at levels common to contemporary cities in the developed world. We review recent epidemiologic studies that evaluated health effects of particulate air pollution and conc...

BACKGROUND Exposure to fine-particulate air pollution has been associated with increased morbidity and mortality, suggesting that sustained reductions in pollution exposure should result in improved life expectancy. This study directly evaluated the changes in life expectancy associated with differential changes in fine particulate air pollution that occurred in the United States during the 198...

Exposure to air pollution is associated with increased cardiovascular risk but the mechanisms are poorly understood. The aim of this investigation was to assess the effect, in rats, of intratracheal instillation of particulate air pollution on leucocyte activation and damage to the vascular endothelium. Rats were exposed to particulate air pollution by intratracheal instillation of PM10. Blood ...

introduction: air pollution is one of the problems of the recent century caused by vehicles, industries and other urban activities. the city of yazd faces air pollution due to its high population, vehicular traffic and industrial places around the city. one of the important parameters of air pollution is suspended air particles that have harmful effects on the health of people, plants and objec...

OBJECTIVES To determine whether previous symptoms or recognized risk factors of cardiovascular ill health, are associated with an increased likelihood of adverse health effects related to particulate air pollution. METHODS Cardiovascular event rates were studied relative to urban concentrations of particulate air pollution and baseline risk factors. The Edinburgh artery study consisted of a c...

In recent years, the haze occurs frequently and air pollution is getting worse in Beijing-TianjinHebei Region, China. The particulate matter pollution characteristic researches are playing a significant role especially in the districts where have higher concentration PM and air pollution. In this study, we collected daily particulate matter (PM10, PM2.5) mass concentration data from 7 air pollu...

background: contemporary development of growing urban communities and increasing the economical and industrial activities in the current century without paying attention to assess the effect of these activities on human health, as the axis of the development, is caused urban air pollution and risks from different pollutant emissions. tehran air pollution has received considerable media coverage...

foliar surface of plants is continuously exposed to the surrounding atmosphere and is, therefore, the main receptor of particulate pollutants. this physical trait can be used to determine the level of particulate pollution in the surroundings, as well as the ability of individual plant species to intercept and mitigate particulate pollutants. in the present study, leaf cuticle characters of fou...
