the Central Pollution Control Board (cpcb) has refuted some findings of the latest Greenpeace report regarding the chlorine industry. It has questioned the claims made by the report that the waste water discharge from a Delhi-based chlor-alkali plant contained a high concentration of mercury during investigations in May last year. Greenpeace scientist Dave Santillo had reported that effluents from the Shriram Food and Fertiliser Industries contained 3.26 mg per litre of mercury, which violates cpcb limits of 0.01 mg per litre. R S Mahwar of the cpcb said that Shriram factory uses the diaphragm cell technology which is far less polluting than a mercury cell- based chlor-alkali plant. Hence, "the observation of Greenpeace cannot be true,' he said.
