conclusions in order to diminish the health impacts of particulate matter in khorramabad, health training for the public, especially for persons with chronic lung and heart diseases, the elderly, and children, should be conducted by health systems to encourage them to reduce their activities during dusty days. materials and methods the pm10 sampling was carried out with a high-volume sampler at...

background dust events are common air pollution events in parts of the world in arid, semiarid, or desert areas. during the last years, air quality of kerman city has been deteriorated due to urban and industrial development as well as population growth. objective the aim of this study was to evaluate the dust fall events in kerman city. material and methods the british jar test assembly method...

The aim of this study was to compare the applicability and the correlation between three commercially available instruments capable of detection, quantification, and characterization of ultrafine airborne particulate matter in the industrial setting of a tapping area in a silicon alloy production plant. The number concentration of ultrafine particles was evaluated using an Electric Low Pressure...

Recent studies have suggested a link between exposure to ambient particulate matter <2.5 microm in diameter (PM(2.5)) and adverse cardiovascular outcomes. The objective of this study was to examine the effects of differing community-level exposure to PM(2.5) on daily measures of blood pressure (BP) among an adult population. During the period May 2002 through April 2003, BP was examined at 2 ti...

The effects of airborne particulate matter (PM) trace elements on health are widely concerned nowadays. Many achievements have been made while many unknowns exist. This article reports the recent research progresses, describes the effects of exposure to PM trace elements on health epidemiological evidence, toxicology findings, and raises some questions for future studies.

The release of molecules adsorbed on the surfaces of amorphous carbon blacks has been studied using liquid-solid chromatography. Adsorbate molecules, adsorbents, and mobile phases were selected on the basis of their relevance as models for the release of toxic agents adsorbed on inhalable environmental particulate matter that originates from the incomplete combustion of organic materials. The p...

To investigate the possible relationship between airborne particulate matter and mortality, we developed regression models of daily mortality counts using meteorological covariates and measures of outdoor PM10. Our analyses included data from Cook County, Illinois, and Salt Lake County, Utah. We found no evidence that particulate matter < or = 10 microns (PM10) contributes to excess mortality i...

Human exposure to fine particles can have significant harmful effects on the respiratory and cardiovascular system. To investigate daily exposure characteristics to PM2.5 with ambient concentrations in an urban environment, a personal exposure measurements were conducted for school children, office workers and at their residents, in the city of Taj 'Agra', India. In order to account for all the...

the state of works of art exhibited inside museums can be strongly influenced by indoor air quality, due to chemical activity of gaseous pollutants and particulate matter. for that reason it is important to carry out periodic air quality controls to check if the concentration levels of air pollutants comply with the limits specified by the national laws. in this work we show results obtained i...
