In urban areas roads surrounded by high rise buildings cause trapping of respirable suspended particulate matter, PM2.5 in the lower regions. Under these situations it is very desirable to know the location of the trapped pollutants in order to find ways to mitigate their health effects. The present study focuses on the identification/prediction of such critical locations using CAL3QHC model.

Concentrations of benzene, a carcinogen Volatile Organic Compound (VOC), have been measured through monitoring campaigns at three different locations on Mathura Road, an intercity road carrying high density traffic in New Delhi.

This work presents an estimate of the air pollution from municipal solid waste transport haulage sector for the city of Kolkata. About 3000 MT/day of solid waste are generated in the city presuming generation rate of 450-500 gm/capita resident/day. On an average, 205 private carriers transport 60% of daily generated garbage (responsible for 44% of total air pollutants from municipal solid waste transport), while around 109 nos. of departmental vehicles transport the remaining 40% of waste (responsible for 56% of total pollution emission from waste transport).

A decade has gone since the first line of metro started in Delhi in 2002. Despite its expansion across the city in the past 10 years neither pollution nor congestion levels have gone down as claimed by its advocates. An analysis of the revenue generated by the Delhi Metro Rail Corporation through property development and the rise of property prices adjacent to metro routes and stations suggests that the metro is entangled with the larger process of gentrification in the city.

One of the vital activities in an urban area is transport. However it also contributes to air pollution, noise pollution and road traffic accidents. Congestion, vibration, community severance and visual intrusion are other transport related problems. Air quality on the city of Kolkata (a metro city of India) seems to be deteriorating. Pollution level in the city and its outskirts is alarming. This is due to old vehicle plying in the road of Kolkata and illegal vehicle plying violating pollution norms, by using bad fuel such as KATATEL.
