Abstract:Â Air Pollution caused due to human activities is one of the major problems in the whole world and India being third largest contributor for emission of green house gases. Thus to control the air pollution, monitoring for the various pollutants as CO, PM10, PM2.5, SOx and NOx were carried out by CPCB in India. In Surat the daily monitoring was carried out at twelve sampling stations all around the city. The Air Quality Index (AQI) was found to fairly harmful with high concentration of Particulate Matter (PM). PM10 is a complex mixture of dry solid fragments, droplets of .liquids or solid cores with coatings which being highly carcinogenic. Present study aims to study the dispersion of PM10 at unsignalised intersection on urban roads. The temporal variation of the PM10 was studied compared with the traffic volume. It was observed that morning peak shows high concentration of PM10 which goes on decreasing towards off peak then again increases in evening peak.
