Delhi: Delhi woke up once again to thick toxic smog on Monday as air pollution levels stayed in the severe to severe plus category across many parts of the city. The worsening air quality has triggered emergency measures while officials warned that long standing negligence in dust control continues to add to the crisis.
Monitoring stations across Delhi NCR recorded extremely high air quality index readings with several areas touching the upper hazardous limits. Poor visibility, a strong smell of smoke and persistent haze marked the start of the day, making outdoor movement difficult for residents.
The Commission for Air Quality Management said recent inspections found repeated lapses in controlling road dust, uncovered debris and poorly maintained stretches, especially in areas with construction and repair works. Officials said such negligence allows fine particles to remain suspended in the air, sharply worsening pollution during winter when weather conditions trap pollutants close to the ground.
With air quality deteriorating further, authorities enforced the highest level of the graded response action plan. Construction and demolition activities have been halted, entry of polluting trucks restricted and older high emission vehicles barred from city roads. Several industries have also been asked to scale down or suspend operations.
Schools have shifted younger students to hybrid or online classes to reduce exposure, while health agencies advised people to stay indoors as much as possible. Airlines issued travel advisories as dense smog affected visibility during early morning and late night hours.
Experts said the current crisis is being driven by a mix of factors including vehicular emissions, construction dust, open burning of waste, crop residue burning in neighbouring states and unfavourable winter weather that prevents dispersion of pollutants.
Doctors warned that prolonged exposure to such air can cause breathing problems, eye irritation and serious health risks for children, the elderly and those with heart or lung conditions. They urged residents to use masks, avoid physical activity outdoors and seek medical help if symptoms worsen.
Despite repeated warnings over the years, environmentalists said the return of extreme smog shows the need for sustained enforcement rather than short term action. As Delhi heads deeper into winter, authorities say strict compliance and public cooperation will be key to preventing the situation from turning even more dangerous.
