The importance of air pollution monitoring networks in urban areas is well known because of their miscellaneous applications. At the beginning of the 1990s, Berlin had more than 40 particulate matter monitoring stations, whereas, by 2013, there were only 12 stations. In this study, a new and free–of–charge methodology for the densifying of the PM10 monitoring network ...

BACKGROUND Exposure to Air pollution PM10 results in lung inflammation increased risk of lung cancer. Regular aerobic exercise improves the inflammatory status in different lung diseases. However, the effects of long-term aerobic exercise on the pulmonary response to PM10 have not been investigated. OBJECTIVES The present study evaluated the effect of aerobic exercise on the lung inflammatory...

A regional, windblown dust modeling system, developed for the Columbia Plateau PM10 Program (CP), was employed to simulate a regional dust storm that occurred during Sept 23 25, 1999. Observed hourly PM10 concentrations exceeded 1000 ug m at downwind urban receptors and extremely poor visibility due to blowing dust in northeastern Oregon caused a fifty car pile-up with the loss of seven lives. ...

BACKGROUND Maternal exposure to ambient air pollution has been associated with an increased risk of congenital heart defects in offspring; however, the results are inconsistent. OBJECTIVES We investigated whether there is an association between prenatal exposure to particulate matter with diameter ≤10μm (PM10) during early pregnancy and fetal cardiovascular malformations. METHODS The gravid...

Abstract: This study built a model with DVI, which is computed by near-infrared and red bands of SPOT-5 image, and observed concentration of PM10 (inhalable particulate matter) to retrieve concentration of PM10 in SPOT-5 image of Beijing urban acquired in 2007. Spatial distribution trends of PM10 are basically identical between retrieved result and observed data. In 2007, inhalable particulate ...

The purpose of this study was to test the hypothesis that particulate matter < or = 10 microns in aerodynamic diameter (PM10) particles have the ability to generate free radical activity at their surface. We collected PM10 filters from the Edinburgh, United Kingdom, Enhanced Urban Network sampling site, removed particles from the filter, and tested their ability to cause free radical damage to ...

one of the major environmental problems in large cities is air pollution. in this study, the monthly and annual changes in the average concentrations of carbon monoxide and pm10 were investigated during a five-year period (winter and fall of 1383-1387 a.h.s) in tehran. the effects of meteorological parameters on these parameters were also investigated. the study area was divided into three zone...

An intensive observation of organic carbon (OC) and elemental carbon (EC) in PM10 and gaseous materials (SO2, CO, and O3) was conducted continuously to assess the characteristics of wintertime carbonaceous aerosols in an urban area of Beijing, China. Results showed that the averaged total carbon (TC) and PM10 concentrations in observation period are 30.2 +/- 120.4 and 172.6 +/- 198.3 microg/m3,...

BACKGROUND Particulate matter (PM) exposure leads to premature death, mainly due to respiratory and cardiovascular diseases. OBJECTIVES Identification of transcriptomic biomarkers of air pollution exposure and effect in a healthy adult population. METHODS Microarray analyses were performed in 98 healthy volunteers (48 men, 50 women). The expression of eight sex-specific candidate biomarker ...

BACKGROUND The ashes and dust resulting from the 2011 eruptions of the Puyehue volcano in Chile more than doubled monthly averages of PM10 concentrations in Montevideo, Uruguay. Few studies have taken advantage of natural experiments to assess the relationship between ambient air pollutant concentrations and birth outcomes. OBJECTIVES In this study we explored the effect of particulate matter...
