Abstract
The oxides of nitrogen (NOx) and Carbon monoxide (CO) concentrations in ambient air in Tuticorin were estimated during January to March 2006. Statistical analysis on so generated database was performed to infer the dominance of meteorological parameters affecting the pollution levels. The NOx and CO concentrations varied from 11.8 and 47.7mg/m3, 0.6 and 1.4 ppm respectively. From the collected database it was observed that, both NOx and CO levels were within the permissible limits set by the United States Environmental Protection Agency (US-EPA). It was also found that wind speed had major influence on the pollutant levels over the other parameters.
