The visuals of devotees taking a dip in the froth-filled waters of the Yamuna River sent chills down the spine of the residents of Delhi.
What is Froth Formation?
- This is a phenomenon that takes place on many lakes and streams.
- Foam bubbles are produced when organic matter decomposes.
- These foam-producing molecules have one end that repels water and another that attracts water and they work to reduce the surface tension on the surface of the water.
- These foam bubbles are lighter than water, so they float on the surface as a thin film that gradually accumulates.
What causes the froth?
- The presence of phosphates and surfactants in untreated sewage from Delhi, Haryana and Uttar Pradesh is a major reason behind frothing.
- While these two components comprise of 1 per cent, the remaining 99 percent is air and water.
What are the sources of pollution that cause foam formation?
- Untreated sewage may contain soap-detergent particles.
- The other sources are industrial effluents, organic matter from decomposing vegetation, and the presence of filamentous bacteria.
- The pollution from the sugar and paper industries in Uttar Pradesh also causes pollution in the Yamuna.
What are its health hazards?
- Short-term exposure can lead to skin irritation and allergies.
- If ingested, these chemicals may cause gastrointestinal problems and diseases like typhoid.
- Long-term exposure to heavy metals in industrial pollutants can cause neurological issues and hormonal imbalances.
