Effects of Water Pollution

Sources and Causes

❶For control of pest pesticides are used in discriminately. For instance, diseases like hepatitis are caused by eating contaminated seafood; developing countries, which often have problems with the quality of water, experience frequent outbreaks of cholera or diphtheria.


Water pollution also affects ecosystems in a negative way, destroying them and thus affecting the ecological situation on Earth. These two factors have an indirect, but strong effect on humanity. As for the direct effects, polluted water causes people to suffer from cholera, diphtheria, skin diseases, reproductive problems, poisoning, and so on.

All of this means that humanity should pay attention to the problem of water contamination, otherwise it will continue to severely hurt itself. Is English your native language?

Water soluble organic chemicals: These are acids, salts and compounds of toxic metals such as mercury and lead.

Variety of organic chemicals: Hot water released by power plants and industries that use large volume of water to cool the plant results in a rise in temp of local water bodies.

A greater threat to human life comes from ground water which is used for drinking and irrigation being polluted. Agricultural practices such as application of large amounts of fertilizers and pesticides, animal feeding operations etc. Large amount of human waste in water increase the number of bacteria such as Escherichia coli and streptococcus species which cause gastro intestinal diseases.

Water bore diseases diarrhea, typhoid etc. If more organic matter is added to water the O 2 is used up. This causes fish and other forms of O 2 dependent aquatic life dies. When the effects are undesirable, eutrophication may be considered a form of pollution National Academy of Sciences, Nixon defined it as an increase in the rate of supply of organic matter in an ecosystem. It is the process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates.

These typically promote excessive growth of algae. As the algae die and decompose, high levels of organic matter and the decomposing organisms deplete the water of available oxygen, causing the death of other organisms, such as fish. Similarities include subsequent negative environmental effects such as anoxia, and severe reductions in water quality, fish and other animal populations may occur.

Other species may experience an increase in population that negatively affects other species in the direct ecosystem. In simpler terms it is the bloom of phytoplankton in a water body. It is often the result of anthropogenic pollution with nutrients, particularly the release of sewage effluent and agricultural run-off carrying fertilizers into natural waters. However, it also occurs naturally in situations where nutrients accumulate e.

Eutrophication generally promotes excessive plant growth and decay, favours simple algae and plankton over other more complicated plants, and causes a severe reduction in water quality.

In aquatic environments, enhanced growth of choking aquatic vegetation or phytoplankton e. The water then becomes cloudy, coloured a shade of green, yellow, brown, or red.

Human society is impacted as well: Health-related problems can occur where eutrophic conditions interfere with drinking water treatment. Bio-magnification, also known as bio-amplification or biological magnification, is the increase in concentration of a substance, such as the pesticide DDT that occurs in a food chain as a consequence of:. Biological Magnification often refers to the process whereby certain substances such as pesticides or heavy metals move up the food chain, work their way into rivers or lakes, and are eaten by aquatic organisms such as fish, which in turn are eaten by large birds, animals or humans.

The substances become concentrated in tissues or internal organs as they move up the chain. Bio-accumulates are substances that increase in concentration in living organisms as they take in contaminated air, water, or food because the substances are very slowly metabolized or excreted.

For example, though mercury is only present in small amounts in sea water, it is absorbed by algae generally as methyl mercury. Bioaccumulation and bio-concentration result in buildup in the adipose tissue of successive trophic levels: Anything which eats these fish also consumes the higher level of mercury the fish have accumulated.
