introduction: air pollution due to particulate matter is a major environmental and health issue in all regions of the world. the aim of this study was to investigate the health impacts of pm10 (particulate matter with an aerodynamic diameter ≤10μm) in khorramabad city, iran in 2014. materials and methods: in this study, pm10 sampling was conducted by a high-volume sampler at flow rate of 1.1-1....

There has been an increased interest in alternative housing for laying hens in certain parts of the world, including the United States. Associated with the movement are many questions to be addressed concerning sustainability of such systems. This study continually quantifies concentrations and emissions of ammonia (NH3), carbon dioxide (CO2), methane (CH4), and particulate matters (PM10 and PM...

Particulate matter is one of the most important indoor air pollutants involved in a number of adverse health effects, such as premature deaths and increased mortality of infants and other parts of sensitive population. This paper focuses on investigation of metal substances of suspended as well as settled particulate matter in indoor environment. The monitoring of particulate matter concentrati...

The PM10 airborne particulate matter with an aerodynamic diameter ≤10 µm is considered as a risk factor of various adverse health outcomes, including lung cancer. Here we described the sampling and composition of PM10 collected from an industrial zone (IZ), and a commercial zone (CZ) of Mexico City. The PM10 was collected with a high-volume sampler in the above mentioned locations and both type...

The estimation of pollution fields, especially in densely populated areas, is an important application in the field of environmental science due to the significant effects of air pollution on public health. In this paper, we investigate the spatial distribution of three air pollutants in Tehran’s atmosphere: carbon monoxide (CO), nitrogen dioxide (NO2), and atmospheric particulate matters less ...

This paper finds that a 10-μg/m3 increase in airborne particulate matter [particulate matter smaller than 10 μm (PM10)] reduces life expectancy by 0.64 years (95% confidence interval = 0.21-1.07). This estimate is derived from quasiexperimental variation in PM10 generated by China's Huai River Policy, which provides free or heavily subsidized coal for indoor heating during the winter to cities ...

Despite an increasing number of recent studies, the overall epidemiologic evidence associating specific particulate matter chemical components with health outcomes has been mixed. The links between components and hospitalizations have rarely been examined in Asia. We estimated associations between exposures to 18 chemical components of particulate matter with aerodynamic diameter less than 10 μ...

Although epidemiological studies have linked particulate air pollution with cardiopulmonary mortality, underlying biological mechanisms remain largely unknown. Unexplored pathophysiological pathways include transient declines in blood oxygenation and/or changes in cardiac rhythm following particulate exposure. In this study, blood oxygen saturation using pulse oximetry (SpO2) and pulse rate wer...

Agricultural machinery can improve agricultural productivity and promote scale operation. However, operations lead to increased dust in farmland affect the atmospheric environment; thus, they have been increasingly emphasized. In this study, effects of wheat cultivation were investigated regarding emissions three kinds particulate matters, namely fine matter (PM2.5), inhalable (PM10) total susp...

back ground and purpose: air pollution in cities thorough the world, is a complex mixture of poisonous compounds which are always combustion products particulate matters (pm) are instant member of this mixture. despite wide spectrum health effects of pm, effects on death seem to be the most important one. the main purpose of this study was to estimate number of cardio pulmonary death in adults ...
