What is the main source of acid rain?
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.
What are two causes of acid rain?
Sulfur dioxide (SO2) and nitrogen oxides (NOx) released into the air by fossil-fuel power plants, vehicles and oil refineries are the biggest cause of acid rain today, according to the EPA. Two thirds of sulfur dioxide and one fourth of nitrogen oxide found in the atmosphere come from electric power generators.
What are the two types of acid rain?
Acid deposition-usually referred to simply as acid rain-actually includes two forms of pollution, wet and dry.
What are 3 causes of acid rain?
Man-made Sources. Human activities leading to chemical gas emissions such as sulfur and nitrogen are the primary contributors to acid rain. The activities include air pollution sources emitting sulfur and nitrogen gases like factories, power generation facilities, and automobiles.
What happens if you drink acid rain?
Humans are affected when we breathe in air pollution, this can cause breathing problems, and even cancer. Drinking water which has been contaminated with acid rain can cause brain damage over time.
How does Acid Rain affect humans physically?
While acid rain cannot harm humans directly, the sulfur dioxide that creates it can cause health problems. Specifically, sulfur dioxide particles in the air can encourage chronic lung problems, like asthma and bronchitis.
Where is acid rain a problem?
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.
How are we trying to fix 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 are the disadvantages of acid rain?
Acid rain affects the fresh water ponds and lakes and destroys the aquatic life as some species of fishes are rare and may be extinct. it can affect the trees particularly those that are high altitude. it can damage historical monuments and buildings.
What are the pros of acid rain?
In fact, the greatest benefits are the 20,000 to 50,000 lives saved per year because of cleaner air and lower pollution levels. SO2 and NOx emissions can lead to the formation of fine particle pollution and smog, also called ground level ozone.
How often does it acid rain?
In these areas, the pH of precipitation can average between 4.0 and 4.5 annually, and the pH of individual rainstorms can sometimes drop below 3.0. In addition, cloud water and fog in polluted areas may be many times more acidic than rain falling over the same region.
What time of year is acid rain more acidic Why?
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. A decrease in pH values from 5.0 to 4.0 means that the acidity is 10 times greater.
What is the pH of acid?
The pH scale ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
