Acid Rain Due To Pollution In The Country – Study

A research by India Meteorological Department and Indian Institute of Tropical Meteorology revealed that in many parts of the country the proportion of harmful acid is increasing day by day in the life giving rainfall, particularly in last 10 years. Study of rain water samples from some places like Nagpur, Mohanbari (Assam), Allahabad, Vishakhapatnam and Kodaikanal in last 10 years shows that the pH level of water is extended from 4.77 to 5.32.
Rain water with pH level below 5.65 is considered acidic; hence these places have received “acid rain”. The pH or potential of Hydrogen level of pure water is 7. In general water with a pH lower than 7 is considered acidic. Acidity increases with the decrease in count.
“It causes leaching of soil nutrients, which means that these nutrients are not available to plants and crops grown in the soil, affecting crop nutrition and productivity. Among other harmful effects, acid rain has had a corrosive effect on monuments in the country like The Taj Mahal”, Experts said.
Acid rain reduces soil nutrition, harmful to aquatic life and affects the health of human being. It gives harmful effects to forest as well as soil and fresh water. It does not directly affect the human health but by mixing of acid in rainwater may give some diseases of heart and lungs like asthma and bronchitis.
The scientists’ analyzed the samples of acid rain collected from different locations (Srinagar, Mohanbari, Jodhpur, Allahabad, Nagpur,Pune, Vishakhapatnam, Port Blair, Kodaikanal and Minicoy in Lakshadweep) in Global Atmosphere Watch (GAW) in India throughout the year shows a decreasing in pH levels.
