How has acid rain affected Canada?
The ongoing industrialization of society has resulted in the increased release of acidic chemicals into the atmosphere. Acid rain has wiped out fishes, molluscs and frogs in thousands of Eastern Canada lakes . Acid rain has wiped out fishes, molluscs and frogs in thousands of Eastern Canada lakes (photo by Don E.
Where does acid rain occur most?
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.
What are the main sources of acid rain in Canada?
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.
Where was the worst acid rain recorded?
China had its worst spell of acid rain in August with Beijing among the hardest hit, the China Meteorological Administration said Friday. The CMA report said 19 of the 155 acid-rain monitoring stations across China recorded acid rain every rainy day last month.
Where is the most pollution in Canada?
By City in Canada
| Rank | City | Pollution Index |
|---|---|---|
| 1 | Hamilton | 55.35 |
| 2 | Regina | 39.86 |
| 3 | Toronto | 37.81 |
| 4 | Winnipeg | 36.73 |
Why does acid rain affect eastern Canada more severely than Western Canada?
Acid rain is a problem in eastern Canada because many of the water and soil systems in this region lack natural alkalinity – such as a lime base – and therefore cannot neutralize acid naturally. However, not all areas in western Canada are naturally protected.
Where has acid rain caused damage?
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.
Where does acid rain form in the atmosphere?
It occurs when emissions from factories, cars or heating boilers contact with the water in the atmosphere. These emissions contain nitrogen oxides, sulfur dioxide and sulfur trioxide, which when mixed with water become sulfurous acid, nitric acid and sulfuric acid.
Why is Eastern Canada affected by acid rain?
Acid rain is a problem in eastern Canada because many of the water and soil systems in this region lack natural alkalinity – such as a lime base – and therefore cannot neutralize acid naturally.
Where does most of Canada’s pollution come from?
Air pollution. Air pollution in Canada is contributed by industrial and vehicular emissions, agriculture, construction, wood burning and energy production. A recent report found that Canadian companies contributed 73\% more to air pollution than companies in the United States.
Where are most of Canada’s largest cities located?
Toronto
Canada is a unique nation, with nearly all of its major cities located along its southern border. Some of its largest cities are Toronto, Ontario (5.9 million), Montréal, Québec (3.9 million), Vancouver, British Columbia (2.5 million) and the nation’s capital Ottawa, Ontario (1.3 million).
Why is there more acid rain on the east coast?
The source of most sulfur dioxide is high-sulfur coal burned in power plants. Controlling this source of sulfur dioxide production can have a major impact on acid rain in Pennsylvania and other regions of the Northeast. Unfortunately, only 30 percent of the nitrogen oxides causing acid rain come from power production.
Why is there no acid rain in Canada?
Many of the waters (streams, rivers, ponds, and lakes) and soils in Canada lack natural alkalinity, such as a lime base, and cannot neutralize acid naturally. Provinces that are part of the Canadian Precambrian Shield, such as Ontario, Quebec, New Brunswick, and Nova Scotia, are most affected.
Why is acid rain bad for the environment?
Acid rain can dissolve certain more soluble elements from the soil, like aluminum. The dissolved aluminum begins to accumulate and can reach toxic levels as it enters local streams and wetlands. Acid rain also removes important nutrients from the soil, such as calcium, potassium, and magnesium.
Where is acid deposition most common in Canada?
Provinces that are part of the Canadian Precambrian Shield, such as Ontario, Quebec, New Brunswick, and Nova Scotia, are most affected. Lakes and soils found in areas of the Canadian Shield in northeastern Alberta, northern Saskatchewan and Manitoba, and parts of western British Columbia, are also sensitive to acid deposition.
What is causing the Canadian Shield’s acidification?
In areas where this buffering capacity is low, like the Canadian Shield, acidic deposition over several years has led to increased acidity of rivers and lakes, and to the accelerated leaching of aluminum from soils. This is seen most in the surface waters of southeastern Canada, where acid rain levels are highest.
