Delhi Air Fouled: Benzene & NO2 Levels Spike in January

Delhi experienced significantly polluted air in January, with nitrogen dioxide (NO2) levels exceeding recommended limits for over 25 days across most monitoring stations. Benzene, a known carcinogen linked to blood cancers, also surpassed World Health Organization (WHO) guidelines on 24 days. While some areas saw reductions compared to the previous year, many locations continued to record elevated NO2 concentrations, such as Burari Crossing and Okhla Phase II.

Vehicular emissions emerged as the single largest contributor to Delhi's pollution load, accounting for 15.1% of the overall pollution. Experts attribute the persistent pollution to a combination of factors including industrial activity, power plants, road dust, construction, and biomass burning. Health experts warn of severe consequences from prolonged exposure.
