US particulate matter air quality improves except in wildfire-prone areas

Chemical Characterization of Particulate Matter at Traffic Prone Roadside Environment in Agra, India

In the present study, size-segregated samples of PM were collected from urban and semi-urban traffic junctions in Agra, India. PM samples were collected during the monsoon season (July to September 2015) using Grimm portable aerosol Spectrometer. The recorded mean concentration of PM10 at urban site was 137.09±61μg/m3 and at semi-urban site was 270.14±21μg/m3, which were higher than the suggest...

Low cost air quality monitors to evaluate nanosized particulate matter. A pilot study

Particulate matter is defined as a mixture of airborne solid particles and liquid droplets that can be inhaled and may cause serious health problems. Such elements are currently measured utilizing air quality monitoring devices that provide information on PM 10 and PM 2.5 levels giving information on pollution levels. However, many difficulties are encountered in the determination of nanosized ...

Correlating Particulate Matter Mobile Source Emissions to Ambient Air Quality

This paper describes the work and results of the second phase of research sponsored by the Federal Highway Administration (FHWA) initiated to study the relationship between traffic activity and ambient PM2.5 concentrations. The study, entitled “Estimating the Transportation Contribution to Particulate Matter Pollution”, had the objective of performing a correlation analyses on particulate matte...
