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 in...
OBJECTIVES The purpose of this study was to examine the association between ambient air pollution and hospitalization for respiratory infections among children who were younger than 15 years in Toronto during a 4-year period (1998-2001). METHODS Exposures averaged during periods that varied from 1 to 7 days were used to assess the effects of air pollutants, including thoracic particulate matt...

life style and life expectancy of inhabitants have been affected by the increase of particulate matter 10 micrometers or less in diameter (pm10) in cities and this is why maximum pm10 concentrations have received extensive attention. an early notice system for pm10 concentrations necessitates an accurate forecasting of the pollutant. in the current study an artificial neural network was used t...
Background and Objective: The presence of fungal bioaerosols in hospitals indoor environments have affected the health of patients with the defect in immunity system. Therefore, determination of the rate and species of these agents is essential. This study aimed to investigate association between fungi contamination and particulate matter (PM10, PM2.5 and PM1) concentrations in the main indoor ...
Background: Exposure to particulate air pollutants is one of the major problems and crises in Tehran metropolis, Iran. Various studies have shown the effect of particulate matter of air contaminants as an increase in cardiovascular and oxidative stress. So, the purpose of this study was to examine the relationship of <2.5 micrometers and <10 micrometers microns particulate matter (PM2.5 and PM1...
conclusions according to the results obtained, the largest numbers of deaths and illnesses were due to the high average pm10 concentration or an increase in the number of days of exposure to this pollutant. background particulate matters have harmful effects on human health and can intensify mortality and disease. objectives the purpose of this study was to evaluate the health impacts of partic...
introduction: air pollution due to particulate matter is a major environmental and health issue in all regions of the world. the aim of this study was to investigate the health impacts of pm10 (particulate matter with an aerodynamic diameter ≤10μm) in khorramabad city, iran in 2014. materials and methods: in this study, pm10 sampling was conducted by a high-volume sampler at flow rate of 1.1-1....
Background and purpose: Particulate matter is one of the main pollutants in underground transport systems. Increase in its concentration leads to health problems in passengers and metro staff. Current research aimed at studying the concentration of particulate matter with aerodynamic diameter less than 10 micron (PM10) in Tehran underground transport system. Materials and methods: In thi...
Particulate matter and photo-oxidant processes in the Eastern Mediterranean have been studied using the UAM-AERO mesoscale air quality model in conjunction with the NILU-CTM regional model. Meteorological data were obtained from the RAMS prognostic meteorological model. The modeling domain includes the eastern Mediterranean area between the Greek mainland and the island of Crete. The modeling s...
