Vehicular particulate emissions in Mysore city

Abstract

The study has employed a model to estimate vehicular PM2.5 and PM10 emission in\rurban area by calculating vehicles travel on the city roads including registered vehicles in the city and\rother vehicles from other cities. Data showed that about half million vehicles travel in Mysore city in\r2010, and it increased by 100 thousands in 2013. Two-wheelers dominated the city roads into half of\rthe vehicle population followed by four-wheelers and other vehicle categories. All vehicles emit more\rthan 1.5 tonne particulates per day in 2010 for each PM2.5 and PM10 and it increased by 100 kg for PM2.5\rand 70 kg for PM10 after the next three years. Nearly half of vehicular PM2.5 was emitted by heavy\rdiesel vehicles like trucks and buses, while PM10 was generated by all vehicle types with almost thesame share. Study revealed that vehicular emissions now become major threats in Mysore city.
