CHENNAI: Laboratory analysis of fine greyish chemical dust that polluted Sathyavani Muthu Nagar in Ennore severely in the end of May has shown high levels of toxic substances like fluoride, lead, uranium, and cadmium.
Releasing the report they had obtained from a National Accreditation Board for Testing and Calibration Laboratories (NABL)-certified lab to the media on Friday, the residents demanded stringent action. They said they continue to face the problem, although the levels of the chemical dust in the air have come down.
