Why is acid rain so bad in China?
A major cause of acid rain in China is the extensive use of coal, which in 2004 accounted for 69% of the energy production. ing ships; 5) and 2× the U.S. emissions of 10 million t in 2002 (6). The extensive coal combustion also results in con- siderable emissions of NOx to the atmosphere.
What is China doing to stop acid rain?
1 issue of ACS’ Environmental Science & Technology. Lei Duan and colleagues explain that China is trying to stop soil acidification by reducing sulfur dioxide pollution from electric power plant smokestacks. Those emissions cause acid rain, which in turn has made vast areas of farmland more acid and less productive.
What causes acid rain?
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.
How much acid rain does China have?
Acid rain is an increasing environmental problem in China. At present SO2 emission is about 20–22 million tons. However with a growing number of large power plants the long-range transport of air pollutants is expected to increase. The highest acid deposition is near the emission sources.
How have some countries tried to reduce 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.
Does acid rain cause potholes?
Carbon dioxide turns rain acidic. … As rain washes over the surface, the water can separate the flexible bitumen from the aggregate material resulting in raveling and pothole formation. Massive sinkholes may also form as the rain dissolves the clay or bedrock beneath.
