The government's move to adopt World Health Organisation (WHO) guidelines on standards for bottled water amounts to buckling under pressure from the Rs 1,000 crore domestic water industry and to lowering of health parameters as the UN body is mum on the presence of several pesticides, the Centre for Science and Environment said. "The WHO has guidelines for only five of the 20 pesticides tested in bottled water and is completely silent on deadly pesticides like chlorpyrifos, endosulphan, phosphamidon and malathion,' said the CSE, which tested the top Indian packaged water brands allegedly carrying excessive pesticide residues.
