Abstract
Air pollution caused due to human activities is one of the major problems in the whole world, and India is the third-largest contributor to the emission of greenhouse gases. Thus to control the air pollution, monitoring for the various pollutants as CO, PM10, PM2.5, SOx and NOx was carried out by CPCB in India. In Surat, daily monitoring was carried out at twelve sampling stations all around the city. The air quality index (AQI) was found to fairly harmful with a high concentration of particulate matter (PM). PM10 is a complex mixture of dry solid fragments, droplets of liquids or solid cores with coatings which is highly carcinogenic. The present study aims to study the dispersion of PM10 at an 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 a high concentration of PM10 which goes on decreasing towards off-peak then again increases in the evening peak.
