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...

Using a UV Raman Lidar for aerosol extinction, and combining Microwave Radiometer derived Liquid Water Path (LWP) with Multifilter Rotating Shadowband Radiometer derived Cloud Optical depth, to get cloud effective radius (Reff), we observe under certain specialized conditions, clear signatures of the Twomey Aerosol Indirect effect on cloud droplet properties which are consistent with the theore...

Introduction: The present study aimed to compare the performance of two widely-used models for spatial assessment of particulate matter less than 10 microns (PM10) in ambient air of Yazd city. Finally, effective factors on concentrations of pollutants and corresponding standards were investigated. Materials and Methods: A number of 13 sampling stations were employed in different areas of Yazd ...

BACKGROUND Few studies have used spatially resolved ambient particulate matter with an aerodynamic diameter of <10 μm (PM10) to examine the impact of PM10 on ischemic heart disease (IHD) mortality in China. The aim of our study is to evaluate the short-term effects of PM10 concentrations on IHD mortality by means of spatiotemporal analysis approach. METHODS We collected daily data on air poll...

Aerosol samples were collected from 22 February 2008 to 15 April 2008 and 17 June 2008 to 23 July 2008 in urban and peri-urban areas of Addis Ababa, Ethiopia, with the aim to assess the spatial and temporal aspects of total suspended particulate (TSP) and particulate matter with aerodynamic diameter less than 10 μm (PM10) and their composition in terms of metallic elements. Sixty six filter sam...

Samples of PM10 and PM2.5 were collected discontinuously between 2003 and 2010 at fifteen monitoring sites (urban, background, industrial) in the south-eastern part of Italy using a mobile laboratory. In total, 483 PM10 and 154 PM2.5 samples were collected and chemically analyzed for the determination of metal content. Data were used to investigate concentration differences among the typologies...
