Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.
Where did acid rain happen 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.
Where is acid rain the worst?
Acid rain is responsible for severe environmental destruction across the world and occurs most commonly in the North Eastern United States, Eastern Europe and increasingly in parts of China and India.
Which country receives most acid rain?
United States and Canada are the countries which are mostly affected by acid rain because of high number of factories, power plants and large number of automotive plants. Europe, Poland, Germany, Czech Republic, Sweden, Norway and Finland are affected because of British and European factories.
Where do acid rains come from? – Related Questions
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.
What is acid rain India?
Acid rain comprises highly acidic water droplets due to air emissions, specifically the disproportionate levels of sulphur dioxide and nitrogen dioxide emitted by vehicles and manufacturing processes. Sulphur dioxide and nitrogen dioxide combine with water molecules to form sulphuric and nitric acid.
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.
Is Taj Mahal affected by acid rain?
Tajmahal is made of marble (CaCO3) which reacts with sulphuric acid of the acid rain causing pitting, decolourization and lusterless.
How do we stop acid rain?
A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help reduce acid rain because they produce much less pollution.
What is the pH of acidic rain?
Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.
Why does Taj Mahal turn yellow?
The Taj Mahal is turning yellow mainly due to these reasons: air pollution, discolouration of marble due to oxidation of its constituents, environmental neglect and wear and tear caused by millions of tourists who visit it every year.
What is the biggest source of pollution in the world?
Detailed Solution. The largest source of pollution in the world is constituted by sewage and garbage which constitute about 80% of the total pollution.
Why is Taj Mahal losing its beauty?
New Delhi: Nano-sized airborne particles of carbon are causing the marble surface of the Taj Mahal to slowly lose its sheen, according to a study into why the iconic monument is getting discoloured.
What is pollution its causes and effects?
Human air pollution is caused by things such as factories, power plants, cars, airplanes, chemicals, fumes from spray cans, and methane gas from landfills, but the ways that humans caused the most air pollution is by burning fossil fuels.
What is meant by visual pollution?
Visual pollution is an aesthetic issue, referring to the impacts of pollution that impair one’s ability to enjoy a view. Overcrowding and excessive advertising are both causes of visual pollution. Causes: The primary sources of visual pollution are. 1. Haze due to dust and air pollution.
What is sound pollution?
Noise pollution is an invisible danger. It cannot be seen, but it is present nonetheless, both on land and under the sea. Noise pollution is considered to be any unwanted or disturbing sound that affects the health and well-being of humans and other organisms. Sound is measured in decibels.
How many types of pollution are there?
The three major types of pollution are air pollution, water pollution, and land pollution. Sometimes, air pollution is visible.
What are the effects of soil pollution?
Soil pollution causes a chain reaction. It alters soils’ biodiversity, reduces soil organic matter and soils’ capacity to act as a filter. It also contaminates the water stored in the soil and groundwater, and causes an imbalance of soil nutrients.
How does pollution affect the balance of the ecosystem?
Air pollution affects ecosystems in a number of ways, altering basic ecosystem functions such as primary production (plant growth) and biogeochemical cycling which in turn affect the ecosystem services and therefore the benefits that humans get from the environment such as timber, clean drinking water and an
What effects does pollution have on animals?
Air pollutants can poison wildlife through the disruption of endocrine function, organ injury, increased vulnerability to stresses and diseases, lower reproductive success, and possible death.
How does plastic waste affect marine life?
Thousands of seabirds and sea turtles, seals and other marine mammals are killed each year after ingesting plastic or getting entangled in it. Endangered wildlife like Hawaiian monk seals and Pacific loggerhead sea turtles are among nearly 700 species that eat and get caught in plastic litter.
