In the present study a monitoring work is under taken to estimate the black carbon aerosol of 4 different cities representing 4 different zones of Odisha state. The monitoring was carried out from December 2008 to November 2009 to study the role of aerosol contamination in different atmospheric condition.

Many air pollutants emitted by industries are site specific. Methyl mercaptan is one such site specific air pollutant suspected in the neighbourhood of SIPCOT Industrial Estate, Cuddalore, Tamil Nadu.

The present study deals with the effect of urbanization and automobile emission on ambient air quality of Bhubaneswar city, Odisha. This paper examines the significant difference in seasonal variations of air pollutant concentrations in the city.

The municipal solid waste (MSW) generated from different activities from various localities and a township in city areas is subject of deep concern for its proper management. The improper management of MSW is a major cause of air pollution. Present research deals with air quality parameter like SPM, RSPM, SO2 and NO2 in surrounding areas of MSW dump site Maihar district, Satna (M.P.).

Present study deals with the stack and ambient air quality monitoring of brick klins in Uttar Pradesh and air dispersion modeling was carried out using the Gaussian model to calculate the ground level concentrations (GLC) of suspended particulate matter (SPM). Based on GLC, criteria has been proposed for installation of new brick kilns and good house keeping practices have been recommended for adoption in and around the brick kilns to reduce the ill effect of pollution on the buildings, human health, flora and fauna.

This study aimed to evaluate toxic emission and combustion characteristics of rubber materials used in Indian NBC respiratory mask. A cone calorimeter was used for combustion study and FT-1R gas analyzer for emissions. Mass loss of rubber materials had indirect relationship with time to ignition.

With an installed renewable energy capacity of over 7,420 MW, Tamil Nadu occupies the top slot amongst all states in the sector. Wind power capacity, which accounts for more than 90 per cent of the state's installed capacity, has been the anchor of its renewable energy installations.

The international energy studies department of the environmental energy technologies division of the Lawrence Berkeley National Laboratory (Berkeley Lab) has released a report that reassessed India's wind potential. The study results points to the scope for detailed research on evaluating the country's true potential in the sector.

The renewable energy certificate (REC) market, after being in operation for only over a year, has already come a long way. Its market value, that is, the total value of REC's cleared, peaked at Rs 632 million in February 2012, compared to a mere Rs 585,000 in March 2011 when the first RECs were traded in India.

Despite global economic slowdown and subsequent policy changes, renewable energies and particularly wind managed to attract substantial funds. Through the year there was hectic activity in the financial circles as new projects attracted funds, loans were given out to finish those in the pipeline and financial support was forwarded to Merger and Acquisition activity.
