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...

متن کاملLevels of PM10 and its Chemical Composition in the Atmosphere of the City of Isfahan
Airborne particulate matter (PM10 ) was collected from the atmosphere of the city of Isfahan. The concentration of heavy metals and anions associated with airborne particulate matter were determined using atomic absorption spectrometric and ion chromatographic techniques. A comparison was made between the variation in the concentration of PM10 and that for heavy metals and...
متن کاملVehicular particulate matter emissions in road tunnels in Sao Paulo, Brazil.
In the metropolitan area of São Paulo, Brazil, ozone and particulate matter (PM) are the air pollutants that pose the greatest threat to air quality, since the PM and the ozone precursors (nitrogen oxides and volatile organic compounds) are the main source of air pollution from vehicular emissions. Vehicular emissions can be measured inside road tunnels, and those measurements can provide infor...
متن کاملDetermination of Polycyclic Aromatic Hydrocarbons in Ambient Urban Air
Polycyclic aromatic hydrocarbons (PAHS) have been determined in the atmosphere of Isfahan, Iran. Airborne particulate matter was sampled using a high-volume air sampler at roof-top level (~6m). Extraction of PAHS from airborne particulate matter has been performed using SFE system and the relationship between the extraction temperature and the recovery of PAHS</su...
