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...

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 particulate air pollution has been associated with increased numbers of daily deaths in dozens of cities around the world, issues still remain about the association. Some have questioned the complex modeling used to control for season in Poisson regression or the role of gaseous air pollutants as potential confounders of the association. I examined the association between deaths and pa...

background & aims of the study: recent studies indicated that particulate matter can have the lung irritation, chronic lung diseases, lung tissue, etc. the aim objective of this study was to assess the mortality associated with exposure to pm10 concentrations in ilam, iran, during 2013. materials & methods: pm10 data were taken from ilam's local agency of environment (i-lae). the annual mo...

In this study, we used both case-crossover and time-series analyses to assess the associations between size-fractionated particulate matter and asthma hospitalization among children 6-12 years old living in Toronto between 1981 and 1993. Specifically, we used exposures averaged over periods varying from 1 to 7 days to assess the effects of particulate matter on asthma hospitalization. We calcul...

Introduction: The aim of this study was to spatial analysis of PM10 concentrations in the ambient air of Yazd in two seasons, and the zoning by using Kriging interpolation method. Finally, different factors affecting the concentrations of PM10 are marked and standards have been investigated Material and methods: The measurement of PM10 particulates was performed by the monitoring device HAZ-...

Recent air quality legislation has placed increased pressure on agricultural producers in several states across the US. In particular, California removed the exemption for agricultural sources from air quality permitting in 2003. Through the use of inaccurate particulate matter emission factors, agricultural operations have been targeted as significant sources of particulate matter emissions. T...
