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 ambient air quality monitoring was carried during the May 2003 to April 2004 along the (NH-6) passing through Jalgaon city. The average concentration of SOx 64 μg/m³, NOx 58 μg/m³, particulates (>10 μ) 515 μg/m³ and respirable dust particulates 224 μg/m³ was reported at Prabhat during the study period (May 2003-April 2004).

The objective of this article is to evaluate (via modeling) the impact of different pollution control scenarios on the shape of the income-emissions relationship. The simulation of emissions and emission controls was conducted using the Climate Change Risk Assessment Framework, which projects SO2 and NOxemissions from energy consumption and conversion and non-energy sources.

The Special Report on Emissions Scenarios (SRES) produced families of 21st century greenhouse gas (GHG) emissions trajectories that aim to be consistent with current knowledge and span a wide range of plausible futures.

Exposure to air pollution affects pulmonary functions adversely. Effect of exposure to pollution on diurnal variation of peak flow was assessed in healthy students. Three hundred healthy age-matched nonsmoker students were studied. They were categorized into two groups on the basis of their residence: commuters and living on campus.

In this paper the authors have estimated for 1990 and 1995 the inventory of greenhouse gases CO2, CH4 and N2O for India at a national and sub-regional district level. The district level estimates are important for improving the national inventories as well as for developing sound mitigation strategies at manageable smaller scales.

The prevalence of respiratory problems and the ventilatory functions in subjects belonging to three sample areas with different levels of pollution was studied to ascertain if there is any association between air pollutant levels and abnormal ventilatory functions.
