Water Pollution in Canada Essay examples -- Environmental Pollution Ess

The industrialization of Canada is severely affecting the nations lakes, streams, and rivers. If whateverthing is not done to improve the situation it is going to drive home some severe environmental problems in its future. The following essay will be looking at the factors that cause contamination, and the effect that pollution has on the environment of Canada. It will also explore some of the methods used to treat and clean-up neutralizewater, and oil spills. Today pollution is very high in both inland and marine irrigate. All different types of water pollution atomic number 18 contributing factors in this problem. Here are some things that are associated with pollution Pathogens Pathogens are disease causing bacteria, viruses, and protozoa. They usually come from human sewer. As pathogen numbers increase, so does the risk of human health.Biochemical Oxygen Demand Organic wastes that decay in a body of water.decrease the amount of atomic number 8 found in it. The living thi ngs in the lake needoxygen to survive. If the oxygen level is depressed to zero, all fish in thelake die. Any decomposition that does not contain oxygen starts to generatenoxious gases such as Hydrogen Sulfide. Pulp and paper mills, and municipalsewage causes BOD. Nutrients Nutrients, particularly north and phosphorus,enrich waters and accelerate the aging of lakes and streams. Also, the resultof this is rich plant life which prohibits recreational activities. Planktonblooms depress oxygen levels (as mentioned before) and therefore, endangerliving organisms. Major sources of nutrients are municipal sewage andagricultural runoff. Toxic Materials Can affect the health of aquatic organismsand their consumers, and the people who drink the contaminated water. Thetoxicants include lead, mercury, DDT, PCB, benzopyrene, oil, and dibutylphthalate. These chemicals enter the lake through dumping by the factories.Temperature Changes Temperature changes from waste heat discharges (like from anu clear power plant) can cause pollution. This happens if their elevationreduces dissolved-oxygen levels, and accelerates eustrophication, which in turnaffects the ecological processes and blocks the migration path of fishes.Acidification Acidification (acid rain and so forth) Is caused by sulfur and nitrogenoxide in the rain, which is caused by automobiles and large industries.Temperature Changes The... ... 40,000gallons) per ton of steel manufactured. A typical metropolitan area discharges avolume of wastewater equal to about 60 to 80 percent of its total dailyrequirements The rest is being used for washing cars, watering lawns, and formanufacturing processes such as food canning and bottling.Infiltration This occurs when sewer lines are placed below the water table or when rainfall goesdown through the earth to the pipe. We do not like it because it means that thepiping administration and the treatment plant have to work extra hardStorm Water Drainage This is simply the water fro m rain, melted snow, etc. draining intoour pipelines and sewers where it goes to a treatment plant to be treated, butthere is nothing wrong with it.In conclusion, From all the points I have brought up it is easy to see thatthe more people there are in the world the more water pollution there is goingto be. That doesnt mean that we have to stop having children, what it means isthat we have to start watching where we drain our polluted water, and start touse our resources more wisely. We should also be more careful with hazardouschemicals , and things like oil drilling, etc.
