The Commission for Air Quality Management in NCR and Adjoining Areas (CAQM) on Sunday pulled up the Delhi Development Authority (DDA) over “evident gaps” and “recurring negligence” in the upkeep of roads in the city.

It said flying squads inspected 136 road stretches maintained by the DDA. Out of them, 15 showed high levels of visible dust, 38 recorded moderate dust levels, 61 had low dust intensity, and 22 were found to have no visible dust.

The squads also found accumulation of municipal solid waste (MSW) on 55 stretches, construction and demolition waste on 53 stretches, and open burning of MSW or biomass on six stretches.

Dust pollution is one of the major sources of air pollution in Delhi.

The CAQM stated that these “observations clearly indicate evident gaps and recurring negligence in the upkeep of the stretches concerned”.
