The seemingly crisp, fresh air inhaled inside the sanitised and cool environs of metro premises or air-conditioned car may actually be teeming with respirable pollutants. Pollutants may be entering underground metro premises not only through air conditioning ducts but also clinging on to the clothes and shoes of passengers. According to experts, not only metro stations, air-conditioned cars and rooms sprayed with freshners are equally, and in cases more, polluted as outdoors.To its credit, the Delhi Metro authorities have actually helped bringing this fact to light by cooperating with a team of IIT-Delhi which collected data in this regard, which is now being analysed.
