After the devastating earthquake in 2001, Central and State Government have provided various incentives for rapid economic development of Kutch district. Mundra, one of the taluka of Kutch District, located on the bank of Northern Gulf of Kutch, having Mundra Port & Special Economic Zone, also witnessed the rapid industrial growth after 2001.

PM10 and PM2.5 samples were collected from a kerbside at a traffic junction in a major metropolis of India during month of December 2005 and their concentrations were calculated. The Pm2.5 fraction in PM10 varied from 18.7 to 72.6%. Such a large variation was correlated with meteorological variables.

Producer gas generated in partial combustion of biomass in the gasifier can be used for heating purposes as also as a supplementary or sole fuel in internal combustion engines. In the present study, producer gas generated from partial combustion of rice husk was used as the fuel for the CI engine.

Noise levels have been monitored at selected locations of Delhi and Roorkee, viz. Rithala (Delhi), Panchsheel Enclave (Delhi), New Friends Colony (NH-2 Delhi) and Gurudwara (NH-73, Roorkee) along with observations of traffic volume, speeds and other geometrical parameters.

The paper presents results obtained in a monitoring study on environmental noise pollution in the city of Aligarh which is a rapidly developing urban centre and a hub of lock industries.

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.

The susceptibility level of different types of plant species to air pollutants in the Tiruchirappalli city (central Tamil Nadu, India) has been conducted on the basis of their air pollution tolerance index (APTI).

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).

In this paper an attempt has been made to undertake performance evaluation of the two well-known regulatory models, AERMOD (07026) and ADMS-Urban (2.2) for a tropical city such as Delhi. The model is applied to estimate ambient air concentrations of SO2 and NO2 for the years 2000 and 2004 over seven sites in Delhi. Both model evaluation and inter-comparison is performed.
