Delhi-NCR witnessed the highest fine particulate matter (PM 2.5) levels in five years this year in September, according to air quality data collated by the Ministry of Earth Sciences’ SAFAR stations. Five out of 10 stations recorded more high PM 2.5 days on average this year as opposed to only two stations in 2014 — Noida and Mathura Road. The average PM 2.5 levels in Delhi, during September, spiked from 54 µg/m3 in 2011 to 88 µg/m3 in 2015. The five new areas with high PM 2.5 included, Ayanagar, Lodhi road, T3, Gurgaon and Dheerpur.
