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...

First-time measurements of the potentially toxic inorganic species of arsenic (arsenite and arsenate) have been obtained in fine (less than 2.5 microns AD) and coarse (greater than 2.5 microns AD) atmospheric particles in the Los Angeles area. A recently developed method that includes procedures for sample collection, preparation, and analysis was used in this study. Size-fractionated aerosol s...

BACKGROUND Epidemiologic studies have reported an association between proximity to highway traffic and increased cardiopulmonary illnesses. OBJECTIVES We investigated the effect of size-fractionated particulate matter (PM), obtained at different distances from a highway, on acute cardiopulmonary toxicity in mice. METHODS We collected PM for 2 weeks in July-August 2006 using a three-stage (u...

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...
