Ambient Air Quality Studies on Cuddalore

Abstract

During the summer of 2009, concentrations of oxides of nitrogen (NO x), oxides of sulphur (So x), suspended particulate matter (SPM) and carbon monoxide (CO) were collected over successive periods of about 8 hour at eight sites. High volume air sampler was used to measure the concentration of Oxides of nitrogen (NO x), Oxides of sulphur (So x), suspended particulate matter (SPM) and battery operated portable CO monitor was used to measure the concentration of carbon monoxide (CO).The results reported pertain to an eight hour successive preliminary air sampling exercise carried out at each of the eight select locations in Cuddalore, a southern semi urban settlement in India. Criteria pollutants SPM, CO, SO 2 and NO 2 measured are found to have either crossed or on the average of crossing the limits, necessitating the immediate installation of a continuous monitoring and control mechanism. While transport related emissions are the major sources of air contamination, increasing civil construction activities also contribute to particulates. The exponential rise in volume of vehicles, disadvantageous traffic flow pattern, differing driving cycle pattern and human interceptions deserve due attention.

Assessment of Indoor Air Quality in an Automobile Industry

“…Air pollution harms every living being, more so the human population and in particular target severely the occupational groups like car drivers, traffic police personnel, parking lot attendants, tunnel workers, road side vendors, owners and employees of uncovered or frequently open commercial establishments in traffic dense and narrow locations, and all users of public places like bus stands, workshops and cinema theaters. The ill effects on health are severe with the fetus, children, and elders and cardiovascular and angina pectoris patients [1] .Also it affects the functioning of heart and brain. At high concentration the impact is fatal.…”

Ambient Air Quality Monitoring of Sankari Crystalline Mining Areas in Salem District Tamil Nadu India

“…Delhi (Prakash et al, 2010), Choudwar, Cuttack district (Bhuyan et al, 2010), Rohtak city (Shukla et al, 2010), Jaipur city (Kumar et al, 2011, Sharma andSharma, 2016), Garhwal (New Tehri), Kumaon (Muktheshwar) (Meena. et al, 2012), Puducherry ( Balashanmugam et al, 2012) 2008). These studies on air pollution in large cities of India concluded that ambient air pollution concentrations are at such levels where serious health effects are possible.…”

“…Higher concentration of oxides of sulfur causes bronchitis and also cause acid rain, sulfurous smog, and reduced atmosphere visibility. A combination of particulate matter with sulfur oxides is more harmful than either of them separately (Balashanmugam et al, 2012). Ozone is produced in the upper atmosphere by solar reaction.…”
