The transport of PM10 over Cape Town during high pollution episodes
PM10 is a notorious air pollutant that often degrades the air quality in Cape Town. Previous studies have attributed high concentrations of PM10 over Cape Town to local sources, neglecting the influence of remote sources. The present study investigates the influence of remote and local pollution …

An Improved Model for Prediction of PM10 from Surface Mining Operations
… an aerodynamic diameter less than 10 microns (PM10). The Industrial Source Complex (ISC3) model, created by the United States Environmental Protection Agency (U.S. EPA), is a model used for predicting dispersion of pollutants from industrial facilities, including surface mines and quarries. The …

Analysis of contributions to the PM10 concentration in a gold mine residential village
… identified as one of the major contributors to PM10 concentration at West Village. The average PM10 gravimetric concentration recorded at West Village was 18.4 μg/m3 and the concentration with the light scatter method was 15.4 μg/m3. Black carbon has been identified as significant contributor to …

Influence of weekdays, weekends, bandhas and weather conditions on particulate matter (PM10) concentrations in the Kathmandu Valley in Nepal
… strikes) and meteorological parameters on PM10 concentrations in the Kathmandu Valley. Within station seasonal differences in PM10 concentrations were compared using t-tests. Linear mixed effects regression models were used to examine the effects of weekends or bandh days on PM10 …

The Measurement and Characterisation of Aerosol in the Urban Atmosphere (PM10) and an Evaluation ofthe Sources of these Particles by Number
… the mass of fine particulate matter below 10 µm(PM10) in air is well documented. Current research suggests that the number, size and shape of particles may be of most concern and that in the urban atmosphere combustion sources of PM10, especially diesel engine sources, dominate the line (< 1 µm) …

Measurement and control of particulate emissions from cattle feedlots in Kansas
… aerodynamic diameter of 10 µm or less (PM10), (3) evaluate the relative effectiveness of pen surface treatments in reducing PM10 emissions, and (4) predict PM control efficiency of vegetative barriers. Concentrations of PM with equivalent aerodynamic diameter of 2.5 µm or less (PM2.5), …

The role of weather and topography in the airborne dispersal of particulate matter in Kent
… in relation to airborne particulate material (PM10) concentrations recorded at 17 pollution monitoring sites throughout Kent for the period 2000 to 2008, as an aid to understanding dispersal patterns in relation to topography. In general, local and synoptic wind direction patterns followed the …

Physico-chemical characterisation of atmospheric aerosols in Tanzania, with emphasis on the carbonaceous aerosol components and on chemical mass closure
… seasons from May 2005 through May 2006. A Gent PM10 stacked filter unit sampler with sequential Nuclepore polycarbonate filters, providing coarse (2-10 µm diameter) and fine (<2 µm) size fractions, and PM2.5 and PM10 tandem filter samplers with pre-fired quartz fibre filters were deployed. …

Association between Air Pollution and Cancer Incidence by region
… method. RESULT: This study found that NOx and PM10-related pollution were mainly associated with cancer. The more concentration of NOx and PM10 were higher, the more cancer incidence ratio increased significantly. Each 10㎍/㎥ elevation in NOx and PM10 air pollution was associated with …

Comparison of three dust sources in Iceland: Dyngjusandur, Mýrdalssandur and Sandkluftavatn
… matter concentrations, PM1, PM2,5, PM4, and PM10, which can have adverse health. The available data reveals that Dyngjusandur experiences the highest number of dust events, followed by Sandkluftavatn and Mýrdalssandur. These findings have implications for public health, as PM10 concentrations …
