Taking our air pollution masks before winter clothing has become a sort of a yearly routine for residents of Delhi and adjoining areas. And this year is not expected to be any different. With the paddy stubble burning season all set to start as well as weather conditions that could bring in dust storms, the air quality is as alarming as ever. Meanwhile, AIIMS director Randeep Guleria has raised a red flag over the matter, saying that pollutions levels are now worse than pre-CNG era thanks to the lack of planning by authorities and the rampant construction work.
