“In yet another damning indiction of air pollution in Delhi, a study has found that a student who travels from IIT Delhi till India Gate and back in various modes of transport, during rush hour, is exposed to 130-250 micrograms per cubic metre (µg/m3) of Particulate Matter (PM) 2.5 every month, according to a study conducted by IIT Delhi with other collaborators. This exposure is much higher than the average of 150 µg/m3 of PM 2.5 levels seen in Delhi from 2012-2014, which is 15 times higher than the World Health Organisation’s recommended annual average. According to the study, published in the international journal Atmospheric Environment, if the student was riding a cycle, the PM 2.5 exposure per kilometre was nine times higher, when compared to the exposure of someone travelling in an air-conditioned car. ‘At current level of concentrations, an hour of cycling in Delhi during the morning rush-hour period results in a PM 2.5 dose which is 40 per cent higher than what commuters are exposed to, in an entire day, in cities like Tokyo, London, and New York,’ stated the study.” The Indian Express.
