Background: Today, air pollution is one of the major problems in large cities including Isfahan. Methods: The objective of this study was to investigate the variations of ozone (O3), carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO2), nitrogen oxides (NOx), sulphur dioxide (SO2), and particulate matter (PM10) concentrations in different months at three stations and also to explore ...

The United States Environmental Protection Agency (U.S. EPA) recently conducted the 1998 Baltimore Particulate Matter (PM) Epidemiology-Exposure Study of the Elderly. The primary goal of that study was to establish the relationship between outdoor PM concentrations and actual human PM exposures within a susceptible (elderly) sub-population. Personal, indoor, and outdoor sampling of particulate ...

A survey was conducted to effectively investigate the characteristics of airborne particulate pollutants PM10 and PM2.5 during the peak tourist season at Mount Wutai Buddhism scenic spot, Shanxi, China. Characteristics of the PM10 and PM2.5 in Wu Ye Temple (core incense burners), Manjusri Temple (a traffic hub), Yang Bai Lin Village (a residential district), and Nan Shan Temple (located in a pr...

a 3-km reach of the luján river was studied by establishing 6 sampling stations, which were from 300 to 500 m apart. the first station was the control reading for river nutrients and particulate material. the second station measured the continuous effluent from a wastewater treatment plant flow of the city of luján and was, therefore, considered a continuous addition point of nutrients. the oth...

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...

Inhalation of particulate matter has presented a challenge to human health for thousands of years. The underlying mechanism for biological effect following particle exposure is incompletely understood. We tested the postulate that particle sequestration of cell and mitochondrial iron is a pivotal event mediating oxidant generation and biological effect. In vitro exposure of human bronchial epit...

Particle emissions are a drawback of rail transport. This work is a comprehensive presentation of recent research into particle emissions from rail vehicles. Both exhaust and non-exhaust particle emissions are considered when examining particle characteristics such as PM10, and PM2.5 concentration levels, size, morphology, composition, as well as adverse health effects, current legislation, and...

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...
