A thick layer of toxic foam was seen floating on the surface of river Yamuna in the national capital. The foam is formed due to the high phosphate content of the water resulting from the excessive release of pollutants in the water body. Dumping of waste also contributes to the forming of toxic foam in the river. The toxic foam poses a health hazard for people living in nearby areas.
