MEASUREMENT OF PM2.5 IN PLAIN AND HILLY AREASIN TRAFFIC CONJUCTION PLACES

MECHANICALENGINEERING

Particulate matter pollution is one of the major environmental concerns in India. Over the past 20 years there has been a considerable increase in the number of motor vehicles. The present study was conducted to assess journey time and roadside exposure to particulate matter along major roads of Plain and Hilly Areas in tamilnadu during February 2018.Measurements of particulate mass were carried out continuously outside the vehicle at 15 different locations in all three cities. Additionally, monitoring was undertaken at a background site throughout the period. The particulate matter (pm2.5) has analyzed by using pm 2.5 and test meter . It also measures humidity and temperature. The highest levels were found at the sites with traffic congestion reflecting, not only, the large contribution of automobile exhaust but also the resuspension of road dust. The majority of public transport vehicles in these cities are not air-conditioned and it is very likely that commuters are exposed to the similar high levels of pollution.
