A suspected leak of noxious gas from the Sterlite Industries plant in Thoothukudi caused nausea and skin irritation among a section of local residents here on Saturday. While Sterlite officials denied any chemical leakage from the factory, Thoothukudi Collector Ashish Kumar said a preliminary inquiry revealed that Sulphur Dioxide (SO2) had leaked from the Sterlite plant. “I have directed the Tamil Nadu Pollution Control Board (TNPCB) officials to undertake a detailed study and submit a report,” Kumar told Express.
