NEW DELHI: The Delhi government wrote to the Centre today requesting it to sprinkle water from choppers or any other aircraft to settle dust, a major source of air pollution in the city. Queries to multiple officials of the the Delhi Pollution Control Committee (DPCC), which maintains the corpus, on the current size of the corpus went unanswered. "I do not know how aerial sprinkling would be executed and what quantum of water we are talking about. An IIT-Kanpur study on Delhi's air pollution, considered the most comprehensive report on the issue till date, had identified road dust as the biggest source of suspended particulate matter in the city. According to the report, road dust makes up over 50 per cent of the total PM10 particles and about 38 per cent of PM2.5 particles.
