      Tuticorin in spotlight again for pollution

      Chennai: The port town of Tuticorin is once again in the pollution spotlight, with the Madras High Court ordering immediate closure of a copper smelting plant run by Sterlite Industries (India) Limited.

      Tuticorin has been a sulphur dioxide (SO2) hotspot in the country for sometime now.

      The Central Pollution Control Board (CPCB) report on National Ambient Air Quality Status 2008 reveals that the two air pollution monitoring stations in Tuticorin — Fisheries College and AVM Jewellery Building — are ranked fourth and fivth in the country's top ten locations with respect to SO2 in residential areas with an annual average concentration of 32 ìg/m3 and 29 ìg/m3. Maharashtra 's Chandrapur was ranked first with 40 ìg/m3.

      In CPCB's 2007 National Ambient Air Quality Status report, the two locations in Tuticorin were ranked sixth and seventh with 29 and 28 ìg/m3. Raja Agencies in Tuticorin was ranked 10 {+t} {+h} in industrial areas in 2007 with 28 ìg/m3.

      The Status / Report of Air Quality in Tamil Nadu 2006-08 released by the Tamil Nadu Pollution Control Board (TNPCB) two months ago has these locations in Tuticorin as the top three stations with highest concentration of SO2 in 2007 and 2008.

      Two stations, both traffic intersections, in Tiruchi — Central bus stand and Gandhi Market —came a distant second with an annual mean concentration of SO2 of 20 ìg/m3.

      Chennai, another port town, had a concentration of about 12 ìg/m3 in Manali, Thiruvottiyur and Kattivakkam.

      Except the three stations of Tuticorin, all the stations in the State were categorised “low polluting” with respect to SO2 by the TNPCB. Classifying the Tuticorin stations as “moderately polluting,” the TNPCB has concluded that Tuticorin needs to be watched perceptively since the presence of SO2 in the air was likely to violate the standards in future.

      According to CPCB, sulphur oxides are emitted in significant quantities from thermal power plants, smelting process of sulphide ores to produce copper, lead and zinc and also from petroleum refining process.

      Source of SO2

      Diesel-driven vehicles are also a specific source of SO2, generated during the combustion process. SO2 can result in respiratory illness, particularly in children and the elderly, and can also aggravate existing heart and lung diseases.
