Moreover, sometimes it can cause heavy metals or pesticide poisoning, because polluted water often contains mercury, plumbum, insecticide, herbicides, and so on TutorVista. As it can be seen, water pollution leads to a number of serious, negative consequences. It destroys animal species that inhabit seas and oceans, and disrupts existing food chains. 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?

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.
This process explains why predatory fish such as swordfish and sharks or birds like osprey and eagles have higher concentrations of mercury in their tissue than could be accounted for by direct exposure alone. For example, herring contains mercury at approximately 0. High levels of organic chemicals acids, salts and toxic metals can make the water unfit to drink, harm fish and other aquatic life, reduce crop yields.
Radioisotopes cause birth defects, cancer and genetic damage. Hot water cause thermal pollution not only decreases the solubility of O 2 but also changes the breeding cycles of various aquatic organisms. Hot water because of thermal pollution not only decreases the solubility of O 2 but also changes the breeding cycles of various aquatic organisms.
Fluorine contamination in drinking water causes Fluorosis, NO 3 contamination causes Blue baby disease Methaemoglobinaceae and PO 4 contamination causes bone marrow disease.

Setting up of effluent and sewage treatment plants to treat waste water can reduce the pollution load in the recipient water.
The treated effluent and domestic water can be reused either for gardening or cooling purposes or wherever possible. Sewage treatment either removes the harmful components or converts them into harmless components. Integrated nutrient management INM and integrated pest management IPM practices will reduce the effects caused due to excess pesticides. For effective control of water pollution, legal provisions regarding water pollution should be enforced by special administrative machinery comprising of highly qualified and experienced personnel.
Domestic sewage can be purified even to make it suitable for drinking; however the process is expensive. Usually, treatment of sewage to reduce its organic matter content is adopted. The water after this treatment is fit for groundwater recharge. After chlorination and proper check, it can be used for drinking. You must be logged in to post a comment.
