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-...

The Federal Reference Method (FRM) ambient PM10 sampler does not always measure the true PM10 concentration. There are inherent sampling errors associated with the PM10 samplers due to the interaction of particle size distribution (PSD) and sampler performance characteristics. These sampling errors, which are the relative differences between theoretical estimation of the sampler concentration a...

Background and purpose: Particulate matter less than 10 microns (PM10) is one of the main pollutants that cause irreparable damage to the environment and human health. The aim of this study was to estimate the health effects of PM10 on human health. Materials and methods: This analytic study was conducted in Bushehr, 2013. PM10 data were obtained from Bushehr Meteorological organization an...

Apparently, breathing clean air is of significant importance to human beings and thus attention to what enters our body through inhalation is on the increase. Tehran’s air pollution has received considerable media coverage in recent years: Since particulate matter (TSP and PM10) is one of the important pollutants in this city, an attempt was made to study TSP and PM10 concentrations and to make...

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...

This study presents the results of the particle size distribution (PSD) analyses of dusts from two agricultural facilities using filters from collocated PM10 and total suspended particulates (TSP) samplers. Ideally, PM10 concentrations obtained using the PM10 sampler should be the same as those using the TSP sampler. However, it was observed from numerous sampling episodes that there exists a b...

Inhalable particulate matter (PM10) is a primary air pollutant closely related to public health, and an especially serious problem in urban areas. The urban heat island (UHI) effect has made the urban PM10 pollution situation more complex and severe. In this study, we established a health risk assessment system utilizing an epidemiological method taking the thermal environment effects into cons...
