This research report pertains to the automobile emissions and the subsequent status of ambient air quality with special reference to carbon monoxide at twenty five stations within the urban limits of

Air Quality Impact Assessment studies of Singoli Bhatwari Hydroelectric Power Plant are reported. The plant site is connected to the dam site via a road. Computations of four pollutants namely Carbon Monoxide, Sulphur Dioxide, Oxides of Nitrogen and Suspended Particulate Matter have been made at various sites around the plant using CALINE-3 model. Sources considered responsible for air pollution are vehicular traffic on road and construction activities around the plant site.

A study of automobile pollution in Kolkata has been made using CALINE 4 model. This model was selected as it offered several advantages over other models. It has been first used as the base model to develop the correction factors for the application of this model for the city of Kolkata, and then the modified model with the correction factors has been validated. Carbon Monoxide was chosen for the model because it is principally emitted from vehicular sources and daily background concentration data of this gas were available for a year for comparative studies.

Five years air monitoring study was carried out to assess the primary air pollutants present in the ambient air in Chennai city during 1999-2003 at two different sampling stations.

The study measures exposure to air pollution in an urban setting in India. Integrated daily exposure to respirable suspended particulates (RSP) and carbon monoxide (CO) was assessed by personal and area sampling from six micro-environments including those for which prior data did not exist in India.

Country-level analyses of global Environmental Kuznets Curve (EKC) relationships that use multicountry panel data sets are likely to suffer from several types of aggregation bias that may explain why previous studies have yielded conflicting results.

This investigation pertains to the emission levels of carbon monoxide, carbon dioxide and hydrocarbons from the vehicles that are plying in Madurai city.
