Temperature Changes: Temperature changes from waste heat discharges (like from a
nuclear power plant) can cause pollution. This happens if their elevation
reduces dissolved-oxygen levels, and accelerates eustrophication, which in turn
affects the ecological processes and blocks the migration path of fishes.
Acidification: Acidification (acid rain etc.) Is caused by sulfur and nitrogen
oxide in the rain, which is caused by automobiles and large industries.
Temperature Changes: The temperature of a body of water is changed by waste heat
discharges, like that of a nuclear power plant. It affects ecological processes
and blocks the migration paths of fish. Because of these pollutants Southern
Saskatchewan and Alberta are threatened by water shortages, and the great lakes
face problems in serious pollution. Rivers and streams are also greatly affected
by these pollutants. The noticeable outcomes of these pollutants are these:
Nitrates in drinking water can cause disease in infants that may sometimes end
in death. Crops in a field can absorb sludge-derived fertilizer containing
cadium, and when humans eat the crop it may result in acute liver and kidney
damage. Sometimes lakes become artificially enriched with nutrients from the
chemical fertilizers that run off cultivated fields into the water. This causes
water that is unpleasant to drink due to bad odor, taste, and algae. Also, acid
rain has left many lakes in Canada totally devoid of life.
There are three major sources of water pollution, they are municipal,
industrial and agricultural. Municipal: This type of water pollution comes from
the wastewater found only in homes and commercial establishments For many years
people have been placing importance on treating the waste to remove harmful
bacteria, etc. from it. Recently we are coming aware of the fact that we have to
improve the ways in which we dispose of the waste. In...
