MEASUREMENT AND STATISTICAL ANALYSIS OF AMBIENT AIR QUALITY STATUS IN CUDDALORE REGION, TAMILNADU, INDIA
Journal Title: Journal of Biological and Scientific Opinion - Year 2014, Vol 2, Issue 2
Abstract
The present study deals with the assessment of ambient air quality at six different locations in Cuddalore region, Tamil Nadu, India. The 24 hours average concentration of suspended particulate matter (SPM), nitrogen dioxide (NO2) and sulphur dioxide (SO2) were monitored at cuddalore region, Tamil Nadu, India. The 24 hour concentration of SPM, NO2 and SO2 were 132.34-197.45, 56.33-89.71 and 58.78-80.68 µg/m3 respectively. In present study, it was observed that concentration of NO2; SO2 levels exceed the permissible limit of National Ambient Air Quality Standard (NAAQS) for residential area. Exposures of these pollutants (NO2 and SO2) above standard levels (NAAQS) causes serious health effects on human health, associated with cardiovascular and respiratory diseases, increased risk of premature birth morbidity and even mortality. There is a significant correlation between SPM with NO2 (r = 0.53), and SO2 (r = 0.46) with linear regression also analyzed. Air Quality Index (AQI) values are in order of S1 > S4 > S5 > S6 > S3> S2, and, it is clearly indicates that among six locations, Nellikuppam (S1) is highly polluted and Thiruvandipuram (S2) is moderately polluted. This is due to combustion processes particularly industrial emissions, motor vehicles and commercial activities.
