When was the first acid rain in India?

In 1974 study was conducted at Trombay in Mumbai which resulted in the release of the first report on acid rain in India. Scientists observed the high incidence of acidic and sulphate compounds in the air.

Where did acid rain occur in India?

Analysis of rainwater samples from Nagpur, Mohanbari (in Assam), Allahabad, Visakhapatnam and Kodaikanal in the decade 2001-2012 showed a pH level varying from 4.77 to 5.32, indicating that these places have actually been receiving ‘acid rain’. Rainwater with pH below 5.65 is considered acidic.

Which country has first acid rain?

In 1852, Robert Angus Smith was the first to show the relationship between acid rain and atmospheric pollution in Manchester, England. Smith coined the term “acid rain” in 1872.

Why did acid rain start?

Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.

When did the first acid rain occur?

Acid rain was first identified in North America at Hubbard Brook in the mid-1960s, and later shown to result from long-range transport of sulfur dioxide and nitrogen oxides from power plants. Hubbard Brook research influenced national and international acid rain policies, including the 1990 Clean Air Act amendments.

Is there acid rain in Mumbai?

Acid rain has also been reported in India. A rainfall of pH 3.5 was reported in Mumbai. The air pollution levels are steadily rising in the metropolitan cities like Kolkata, Delhi, and Mumbai.

When did acid rain happen?

During the 1970s and ’80s the phenomenon called acid rain was one of the most well-known environmental problems in Europe and North America, appearing frequently in news features and mentioned, on occasion, in situation comedies of the day.

How did acid rain start?

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

When did acid rain start?

It began in the 1950s when Midwest coal plants spewed sulfur dioxide and nitrogen oxides into the air, turning clouds–and rainfall–acidic. As acid rain fell, it affected everything it touched, leaching calcium from soils and robbing plants of important nutrients.

How has acid rain affected Taj Mahal?

When the acid rain attacks or falls on the Taj Mahal the monument gets corroded. Taj Mahal is completely made of marble, acid rains react with marble to form a powder-like substance which is then washed away by the rain. This phenomenon is called marble cancer.

How is acid rain affecting India?

Acid rain can reduce soil nutrition, corrode buildings (such as Taj Mahal), kill aquatic life and increase heavy metal concentration in soil and water, impacting human health.

Why the Taj Mahal is turning yellow?

These pollutants – sulphur dioxide, nitrogen dioxide and mainly carbon-based particulates – have steadily weathered and eroded the Taj’s brilliant white facade, giving it a yellow sheen.
