INFO:

As Delhi grapples with rising air pollution, toxic foam was seen floating on the Yamuna River in the Kalindi Kunj area on October 19. The toxic foam is due to the high phosphate content in the Yamuna river which can cause skin and respiratory problems.  The national capital's overall Air Quality Index fell to 293 and was marked under the 'Poor' category. As per the Central Pollution Control Board, the AQI when marked under the 'Poor' category can cause breathing discomfort to most people on prolonged exposure, whereas, when under the 'Very poor' category can cause respiratory illness on prolonged exposure.
