OBJECTIVES To investigate the sources of high concentrations of particles of < 10 microns diameter (PM10) in classrooms, observed in a previous study on childhood exposure to PM10, and to study the correlation between classroom and outdoor concentrations of mass and elements of PM10. METHODS Measurements of PM10 were conducted in two schools and outdoors in Amsterdam, the Netherlands. Averagi...
background & aims of the study: recent studies indicated that particulate matter can have the lung irritation, chronic lung diseases, lung tissue, etc. the aim objective of this study was to assess the mortality associated with exposure to pm10 concentrations in ilam, iran, during 2013. materials & methods: pm10 data were taken from ilam's local agency of environment (i-lae). the annual mo...
Recently, attention has focused on whether particulate air pollution is a specific trigger of myocardial infarction (MI). The results of several studies of single locations assessing the effects of ambient particular matter on the risk of MI have been disparate. We used a multicity case-crossover study to examine risk of emergency hospitalization associated with fine particulate matter (PM) wit...
Background and purpose: Air pollution is one of the most important environmental issues and its impact on human health has been proven in the 20th century. Many air pollutants such as CO, NO2, SO2, O3, particulate matter (PM10), heavy metals, radon, etc. could have negative health effects. The aim of this study was to determine the concentration of PM10, lead, and radon in the air of Spahanshah...
background & aims of the study: in this study, we evaluate the respiratory deaths which were caused by exposure to pm10 in ahwaz, bushehr and kermanshah cities of iran during 2015 by air model q2.2.3. materials and methods: the required data gathered from the department of environment and meteorological organization in three study areas. data were analyzed, using excel software at the next stag...
Background and Objective: This study was conducted to investigate the long-term temporal trends and spatial variations of ambient PM10, PM2.5, O3, concentrations in Tabriz city during the years 2006-2017. Materials and Methods: Real-time hourly concentrations of PM10, PM2.5, O3 measured at nine air quality monitoring stations (AQMSs) were obtained from the Tabriz Department of Environment (TDo...
BACKGROUND Air pollution in Darwin, Northern Australia, is dominated by smoke from seasonal fires in the surrounding savanna that burn during the dry season from April to November. Our aim was to study the association between particulate matter less than or equal to 10 microns diameter (PM10) and daily emergency hospital admissions for cardio-respiratory diseases for each fire season from 1996 ...
Continuous and simultaneous observational particulate matter (measured as PM10), nitrogen dioxide (NO2) and oxides of nitrogen (NOx) data were captured at a kerbside site alongside a major highway in Auckland, New Zealand, and at a pair of setback sites within 250 m of the highway, day and night over 8 weeks. The three measurement sites were intended to allow emissions from the highway to be la...
Air pollution, a cardiovascular risk factor, might exert its effects through the microcirculation. Fundus photography allows study of the retinal vasculature in vivo. Short-term PM10 exposure is associated with changes in retinal blood vessels, but the underlying mechanism remains unknown. Expression of MIR21, MIR222 and MIR146A, gene regulators involved in oxidative stress and inflammatory pro...
