Eastern Canada generally experiences high levels of acid deposition due to the large quantities of acidic pollutants emitted into the atmosphere each year in the heavily populated areas (the southern border and the lakes) of Canada and from pollution imported from the US.
Why is eastern Canada more 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.
Why does the East have more acid rain?
The areas of greatest acidity (lowest pH values) are located in the Northeastern United States. This pattern of high acidity is caused by the large number of cities, the dense population, and the concentration of power and industrial plants in the Northeast.
Where does acid rain occur the most 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.
What causes Canada’s acid rain problem?
Emissions of sulphur dioxide (SOx) and nitrogen oxides (NOx) from coal- and oil-fired power plants, smelters, motor vehicles, and other human-related sources are the principal contributors to acid deposition, ground-level ozone, and particulate matter.
Why is acid rain more of an environmental problem in the Northeast than it is in other parts of the US?
In areas such as mountainous parts of the Northeast United States, the soil is thin and lacks the ability to adequately neutralize the acid in the rain water. As a result, these areas are particularly vulnerable and the acid and aluminum can accumulate in the soil, streams, or lakes.
Why is eastern US more acidic?
It is well known that the eastern U.S. is plagued with many coal burning, sulfur emitting power plants that discharge large amounts of CO2 and SO2 (See Figure 3) into the atmosphere. This simple fact alone can easily account for the low pH of precipitation in the region surrounding Pearsons, VW.
Where does acid rain appear the most?
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.
Which country has the most acid rain and why?
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 is the location of the highest acid rain 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.
When was acid rain the worst in Canada?
1980s
In the 1980s, the threat of acid rain in Canada and the U.S. had become a brewing environmental crisis. In areas of Southern Ontario, lakes that once were teeming with wildlife were on the verge of becoming dead lakes, void of fish and other aquatic species.
When did acid rain become a problem in Canada?
Between 1972 and 1977, evidence linked acidification to the long-range transport of sulphur dioxide from sources in other countries – for Scandinavia, nations of continental Europe, and for Canada, the United States; within Canada there was also long-range transport between provinces.
What is the main cause of acid rain in Canada’s Great lakes region?
The chemicals from the mining industry released into the air causes acid rain which in then tarnish the Great Lakes from the precipitation of the water cycle. Automobiles have also been known to emit smog and cause acid rain that will then be rained into the lakes.
What is the main cause 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 are 3 causes of 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.
Why does acid rain occur more in the northern hemisphere?
Acid rain occurs mostly in the Northern Hemisphere — the more industrialized, dirtier half of the globe. Winds can sweep up emissions from high smokestacks and carry pollutants far from their original sources, crossing state lines and national borders in the process.
Why the effects of acid deposition are more severe along the east coast compared to the rest of the United States?
Lakes and Streams
Greatest acidity occurred along the Atlantic coast, where waters have naturally higher acidity to begin with.
Why is acid rain so heavy near the coastlines?
It’s hard to find an area that isn’t close to some small stream or larger creek or river. All that land is catching acid rain, and funneling it to the rivers, which take it to the ocean. So, that is why there is a problem, especially along coastal waters, where the rivers end their courses.
What regions are most acidic?
The Indian Ocean, it turns out, is ten percent more acidic than average. And colder oceans near the poles are acidifying far more rapidly than temperate ones. Waters near Iceland as well as the Antarctic Ocean, for instance, are acidifying at an astonishing rate of five percent per decade.
Why is the eastern part of the US more humid than the western part?
Because warm air can hold more moisture than cool air, it feels more humid and the dewpoint temperatures are frequently higher along the eastern seaboard than they are along the west coast in the summer months.
Why is the Pacific more acidic?
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean’s average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.
