Abstract

To assess the spatiotemporal distribution patterns of Sulphur dioxide (SO2) and its concentration data sets measured from different types of AQM stations in and around dhenkanal,Industrial project sites near Banarpal, Angul, Orissa, . The target AAQ monitoring stations were selected to represent the urban traffic (A-type), urban background (B-type), suburban(C-type) and rural areas (D-type) centering 10kms radius of Banarpal areas. Banarpal is 14 km away from the District head quarter Angul . NH-42 runs from Cuttack to Rourkela passing through Banarpal. Most of the industrial activities are carried out within 10km of the town, like Talcher Thermal Power Station of NTPC, NALCO, Bhushan Steel, Navabharat Ferro Alloys, BRG Steel, Hind Metals, and Rana Sponge etc. The mean concentrations of SO2 were clearly distinguished both between the A- and B-type stations and between the C- and D-type stations. The mean concentration of SO2 in urban traffic and urban background(A,B-type)varies from 4?1.6 to12?2.0; sub urban (C-type)is from 4.0?1.0 to 5?1.0 and the mean concentration of SO2 inRural areas(D-type) varies from 4.0?0.85 to 5.0?1.The comparison of seasonal patterns indicated that the SO2 values tend to consistently peak increase during the winter (or, spring) months of A&B type of stations as 8.0?g/m3 to 18?g/m3, C-type 9.0?g/m3to 12?g/m3and D-type 5.0?g/m3 to 7.0?g/m3 than other seasons. The long term compared SO2 data indicates the gradual and substantially decrease the values in most of the study sites. However, the patterns for such annual changes tend to differ between major urban (A&B), Suburban(C) and Rural stations (D). It was found that such decreasing trends were clearer in the former pairs than others. The overall results of our analysis from diverse AQM station types indicate that the distribution characteristics of SO2 may have been controlled rather sensitively through time by social &environmental changes, which forced the reduction of SO2 emissions.
