Potential aerosol release rates during wind erosion of soils have been quantified by such methods as sandSuspendable-size soil particles are released during wind erosion and blasting aggregates in laboratory settings (Alfaro et al., transported downwind, impacting regional air quality. Of particular concern are those particles with a mean aerodynamic diameter of 1998), measuring concentrations ...

This paper examines the associations between average daily particulate matter less than 10 microns in diameter (PM10) and temperature with daily outpatient visits for respiratory disease including asthma, bronchitis, and upper respiratory illness in Anchorage, Alaska, where there are few industrial sources of air pollution. In Anchorage, PM10 is composed primarily of earth crustal material and ...

Exposure to urban airborne particles is associated with an increase in morbidity and mortality. There is little experimental evidence of the mechanisms involved and the role of particle composition. We assessed cytotoxicity (crystal violet assay), apoptosis [terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) or annexin V assay], DNA breakage (comet assay), and product...

Mexico City’s bus rapid transit (BRT) network, Metrobus, was introduced in an attempt to reduce congestion, increase city transport efficiency and cut air polluting emissions. In June 2005, the first BRT line in the metropolitan area began service. We use differences-indifferences and quantile regression techniques in undertaking the first quantitative policy impact assessment of the BRT system...

Severe health risks caused by PM10 (particulate matter with an aerodynamic diameter ≤10 μm) pollution have induced inevitable economic losses and have rendered pressure on the sustainable development of society as a whole. In China, with the "Polluters Pay Principle", polluters should pay for the pollution they have caused, but how much they should pay remains an intractable problem for policy ...

Subway lines are responsible for 20% of the total passenger traffic in Tehran. Particulate matter is one most important major pollutants subway stations and increasing their concentration leads to numerous health consequences passengers employees. This study aims investigate PM10 PM2.5 four underground metro compare them with these particles open air. Seasonal sampling (April 2018 - April 2019)...

conclusions in order to diminish the health impacts of particulate matter in khorramabad, health training for the public, especially for persons with chronic lung and heart diseases, the elderly, and children, should be conducted by health systems to encourage them to reduce their activities during dusty days. materials and methods the pm10 sampling was carried out with a high-volume sampler at...

We used Health Impact Assessment (HIA) to analyze the impact on a given population's health outcomes in terms of all-causes mortality and respiratory and cardiovascular hospitalizations attributable to short-term exposure to particulate matter less than 10 μm diameter (PM10) in Bejaia city, for which health effects of air pollution have never been investigated. Two scenarios of PM10 reduction w...

Emissions rates for particulate matter less than 10 m (PM10) and ammonia (NH3) from commercial tunnel–ventilated broiler houses in central Texas were analyzed using linear regressions to develop emission rates as a function of bird weight for broilers on litter. Interior ambient temperature and relative humidity were not found to be significant factors affecting emissions. From the regression e...
