Immersion of idols changes surface tension of city-based water bodies

  • | Wednesday | 13th September, 2017

Basically the pure water has the scientific value of surface tension 72 dyne/cm. "We witnessed that the surface tension had remarkably changed from the expected value except at the Kalamba Lake, due to prohibition to immerse any idol there this year. He said that such polluted water may affects directly on the biodiversity at that water resource.The students of the Physics department of the college under the guidance of Professor Milind Karanjkar, Head of the Department of Physics Vivekanand College, Kolhapur studied the surface tension of water after the immersion is finished. "He added that the team of four students and the staff members of the Physics department measured the surface tension in Rankala Lake, Kalamba Lake, Irani quarry, Koti Thirth pond, and Panchaganga River. It shows whether the water is polluted, clean or is having impurities in it.

Kolhapur: An experimental research done after the Ganesh idol immersion process on September 6 and 7, earlier this month, by the city-based Vivekanand College students and faculty member revealed that there was a change in the surface tension of the water sources in the city, where the Ganesh idols were immersed.Elaborating on it, Milind Karanjkar, Head of the Department of Physics Vivekanand College, Kolhapur said, "It is one of the most important physical properties of the water. It shows whether the water is polluted, clean or is having impurities in it. Basically the pure water has the scientific value of surface tension 72 dyne/cm. However, if it is lower than 72 units then we can say that the water is having soluble impurities, and if it is higher, then it can be assumed that the water source contains the substances which are not readily soluble in the said source."He added that the team of four students and the staff members of the Physics department measured the surface tension in Rankala Lake, Kalamba Lake, Irani quarry, Koti Thirth pond, and Panchaganga River."We witnessed that the surface tension had remarkably changed from the expected value except at the Kalamba Lake, due to prohibition to immerse any idol there this year. It was lower than 72, but still has traces of soluble impurities, probably due to various other reasons," he added.According to Karanjkar, only Ganesh idol immersion is not responsible for the change in the surface tension of the water, but the existing pollutant sources from different areas also contributed in the changed figures.He added that the activities like the washing clothes, washing animals, vehicles, insertion of polluted water in the form of nullah, and no proper flow of water can contribute in the pollution and eventually change in the surface tension of water. He said that such polluted water may affects directly on the biodiversity at that water resource.The students of the Physics department of the college under the guidance of Professor Milind Karanjkar, Head of the Department of Physics Vivekanand College, Kolhapur studied the surface tension of water after the immersion is finished.
