Abstract Introduction: Airborne pollution in such public environments as schools has adverse health effects on pupils and teachers who spend a noticeable amount of time in the school. Therefore, this study aimed to measure the suspended particles concentration of indoor and outdoor air of Yazd schools as well as to determine the influencing parameters on the pollution intensity. Metho...
BACKGROUND Daily variations in ambient particulate air pollution have been associated with respiratory mortality and morbidity. AIMS To assess the associations between urinary concentration of lung Clara cell protein CC16, a marker for lung damage, and daily variation in fine and ultrafine particulate air pollution. METHODS Spot urinary samples (n = 1249) were collected biweekly for six mon...
Though water and land pollution is very dangerous, air pollution has its own peculiarities, due to its transboundary dispersion of pollutants over the entire world. Air pollution is one of the serious problems faced by the people globally, especially in urban areas of developing countries like India. All these in turn lead to an increase in the air pollution levels and have adverse effects on t...
Recently, indoor air quality has attracted the attention of policymakers and researchers as a critical issue like that of external air pollution. Indoor air quality is more important as people spend time longer indoors than outdoors. Indoor environments are closed compared to external environments providing less opportunity for the pollutants to dilute. The emissions contain many substances tha...
The presence of biological particles and non-biological pollutants in the atmosphere is closely related to the incidence of adverse reactions affecting human health. The present study demonstrates different effects of ambient air pollution and meteorological factors on pollen concentration of selected taxa in the atmosphere. The investigation was carried out in Szczecin, Poland, between 2006 an...
Abstract Background and Objective: Air pollution can harm humans and the environment. To reduce the effect of these parameters in the emissions of air pollutants known to the local topographical features and climatic conditions are factors. The purpose of this study, monthly and seasonal variations are contaminants and their relationship with meteorological parameters. Methods: the presen...
BACKGROUND Long-term exposure to particulate matter air pollution has been associated with increased cardiopulmonary mortality in the USA. We aimed to assess the relation between traffic-related air pollution and mortality in participants of the Netherlands Cohort study on Diet and Cancer (NLCS), an ongoing study. METHODS We investigated a random sample of 5000 people from the full cohort of ...
The present study applies the model of American Meteorological Society-Environmental Protection Agency Regulatory Model (AERMOD) to investigate NO2 emissions from Besat thermal power plant, which is fuelled by natural gas to function. Results indicate that the simulated concentration of NO2 based on AERMOD, does not exceed NO2 concentration limit, set by the Iranian Ambient Air Quality Standard...
