The burning of garbage at a site near Kukatpally and the spiralling smoke had the residents of nearby colonies on Thursday worried over the health impacts.

The residents claimed that the garbage accumulated from surrounding areas was burnt at open plots near Metro Mall since morning. “The smoke from garbage heap is spreading into the nearby residential areas,” said a resident of Sangeet Nagar, Jai Prakash.

Expressing apprehensions over the pollution impact, he said it could result in release of harmful dioxins.

When contacted, the PCB officials said the issue was earlier discussed with the GHMC since it involved the municipal garbage. The PCB night patrol teams would visit the site and check into the complaints, the official said.
