What are the main causes of pollution in the Great Lakes?
The Great Lakes suffer from three main sources of pollution: Heavy industry, manufacturing, and agriculture. This does not account for all of the pollution, but are a majority of the blame. Chemical pollution, Plastic pollution, and Nutrient pollution have been devastating to The Great Lakes.
What causes the acid rain in Canada around the Great Lakes?
Coal-burning factories, cars, & trucks release chemicals that pollute the air. The pollutants mix with water molecules in clouds and turn the water acidic. Southern Canada (near the Great Lakes region) experiences the highest levels of acid rain. …
What are the effects of acid rain?
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.
What parts of Canada are most affected by acid rain?
Provinces that are part of the Canadian Precambrian Shield, such as Ontario, Quebec, New Brunswick, and Nova Scotia, are most affected.
Is acid rain still a problem in Canada?
Although the acidity of acid rain has declined since 1980, rain is still acidic in eastern Canada. For example, the average pH of rain in Ontario’s Muskoka-Haliburton area is about 4.5 – about 40 times more acidic than normal. Reductions in the acidity of acid rain are due to reductions in emissions of SO2 .
What are the main causes of acid rain in Canada?
Acid rain is caused largely by sulphur dioxide and oxides of nitrogen emitted by industrial activities such as coal burning. The gases dissolve in rainwater to form acids. Much of this industry is based in the United States, but the weather exports pollution north of the border.
Where is acid rain a problem?
Affected areas Places significantly impacted by acid rain around the globe include most of eastern Europe from Poland northward into Scandinavia, the eastern third of the United States, and southeastern Canada. Other affected areas include the southeastern coast of China and Taiwan.
What are the different causes of 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.
What will happen if acid rain continues?
Air pollution like sulfur dioxide and nitrogen oxides can cause respiratory diseases, or can make these diseases worse. Also, nitrogen oxides cause ground-level ozone. This ground-level ozone causes respiratory problems, like pneumonia and bronchitis, and can even cause permanent lung damage.
Can acid rain burn your skin?
Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this, never acidic enough to burn your skin. Rain is always slightly acidic because it mixes with naturally occurring oxides in the air. Unpolluted rain would have a pH value of between 5 and 6.
What color is acid rain?
When you add acid, bromothymol blue turns yellow; when you add a base (like sodium sulfite), it turns blue. Green means neutral (like water).
Which state has the highest report of acid rain?
Is acid rain increasing?
THE rapid rate at which rainfall is growing more acidic in more areas has led many scientists and governmental officials to conclude that acid rain is developing into one of the most serious worldwide environmental problems of the coming decades.
How long has acid rain been a problem?
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.
When was acid rain at its worst?
Which country has first acid rain?
Who first discovered acid rain?
Robert Angus Smith
When the word acid rain was first used?
Which acid is mostly associated with acid rain?
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.
What pH is acid 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.
What is the pH of stomach acid?
The normal volume of the stomach fluid is 20 to 100 mL and the pH is acidic (1.5 to 3.5). These numbers are converted to actual acid production in units of milliequivalents per hour (mEq/hr) in some cases. Note: Normal value ranges may vary slightly depending on the lab doing the test.
What is the pH level for pure water?
The measurement of alkalinity and pH is needed to determine the corrosivity of the water. The pH of pure water (H20) is 7 at 25oC, but when exposed to the carbon dioxide in the atmosphere this equilibrium results in a pH of approximately 5.2.
