background : in recent years, due to its distinct geographical circumstances and position in a gorge, and accumulation of pollutants in surface air, isfahan, iran has become one of the most polluted cities in the iran in terms of air pollution. the purpose of this study was to estimate cardiovascular and respiratory diseases attributed to particulate matter of less than 10 microns (pm 10 ) in i...
BACKGROUND Chronic epidemiologic studies of particulate matter (PM) are limited by the lack of monitoring data, relying instead on citywide ambient concentrations to estimate exposures. This method ignores within-city spatial gradients and restricts studies to areas with nearby monitoring data. This lack of data is particularly restrictive for fine particles (PM with aerodynamic diameter < 2.5 ...
Land Use Regression (LUR) models have been used increasingly for modeling small-scale spatial variation in air pollution concentrations and estimating individual exposure for participants of cohort studies. Within the ESCAPE project, concentrations of PM(2.5), PM(2.5) absorbance, PM(10), and PM(coarse) were measured in 20 European study areas at 20 sites per area. GIS-derived predictor variable...
varicocele is one of the most common causes of primary male infertility. pilea microphylla (pm) is being used as folk medicine. this study was aimed to investigate the effects of pm in a rat model of varicocele. a total of 30 male wistar rats were divided into control, sham, varicocele, accessory varicocele and pm-treated groups. after 10 weeks of varicocele induction, sperm parameters and chro...
background: the aim of study was to measure particle matter concentration (pm 1, pm 2.5 and pm 10 ) during normal, semi-dust and dust-event days. the impacts of some meteorological factors on particle matter concentrations were also investigated. methods: samples were collected by grimm aerosol technik (gmbh model 1/108 germany) from november 2011 to may 2012. temperature, humidity, wind speed ...
