Mention types of water pollutants and their effects on the human body?

1. Bacteria, viruses, protozoa and parasitic worms.

Sources:

Human & animal wastes.

Harmful effects:

Disease

2. Oxygen Demanding Wastes

Organic waste such as animal manure and plant debris that can be decomposed by aerobic bacteria.

Sources:

Sewage, animal feedlots, paper mills, an food processing facilities.

Harmful effects:

Large populations of bacteria decomposing these wastes can degrade water quality by depleting water of dissolved oxygen. This causes fish and other forms of oxygen-consuming aquatic life to die.

3. Inorganic chemicals

Water soluble, acids, compounds of toxic metals such as lead , arsenic and selenium (Se) and (3) salts such as sodium chloride (NaCl) in ocean water and fluorides found in some soils.

Sources:

Surface runoff, industrial effluents and household cleansers.

Harmful effects:

Can 1) make fresh water unusable for drinking or irrigation, 2) cause skin cancers and crippling spinal & neck damage (F) 3) damage the nervous system, liver and kidneys (Pb and As), 4) harm fish and other aquatic life, 5) lower crop yields, and 6) accelerate corrosion of metals exposed to such water.

4. Organic Chemicals

Oil, gasoline, plastics, pesticides, cleaning solvents, detergents

Sources:

Industrial effluents, household cleansers, surface runoff from farms & yards.

Harmful effects:

Can 1) threaten human health by causing nervous system damage (some pesticides), reproductive disorders (some solvents) and some cancers (gas, oil, solvents). 2) harm fish and wildlife.

5. Plant Nutrients

Water soluble compounds containing nitrate, phosphate and ammonium ions.

Sources:

Sewage, manure, and runoff of agricultural and urban fertilizers.

Harmful effects:

Can cause excessive growth of algae & other aquatic plants, which die, decay, deplete water of dissolved oxygen and kill fish. Drinking water with excessive levels of nitrates lowers the oxygen-carrying capacity of the blood and can kill unborn children & infants (blue baby syndrome)

6. Sediment

Soil, silt

Sources:

Land erosion

Harmful effects:

Can 1) cloud water and reduce photosynthesis 2) disrupt aquatic food webs, 3) carry pesticides, bacteria & other harmful substances, 4) settle out and destroy feeding and spawning grounds of fish, and 5) clog and fill lakes, artificial reservoirs, stream channels & harbors.

7. Radioactive Materials

Radioactive isotopes of iodine, radon, uranium, cesium and thorium.

Sources:

Nuclear and coal-burning power plants, mining and processing of uranium and other ores, nuclear weapons production, natural sources.

Harmful effects:

Genetic mutations, miscarriages, birth defects, and certain cancers.

8. Heat (Thermal pollution) (excessive heat)

Sources: Water cooling of electric power plants and some types of industrial plants. Almost half of all water withdrawn in the United States each year is for cooling electric power plants.

Harmful effects:

Lowers dissolved oxygen levels & makes aquatic organisms more vulnerable to disease, parasites, and toxic chemicals. When a power plant first opens or shuts down for repair, fish and other organisms adapted to a particular temperature range can be killed by the abrupt change in water temperature- known as thermal shock

Types Of Water Pollution

For the best answers, search on this site https://shorturl.im/axbDD

the polluted water can very badly affect human body as below- 1) water can contains hazzardous chemicals ie pesticides, organic contains, industrial effluents. 2) the pollutants containts may be bromide, mercury,sulphide, organo chlorine ,organo phosphorus, etc, 3)all the above containts are carconogenics, that causes sevral types of cancers. 4) in polluted water has very low oxygen contains and higher carbon contain, 5) many types of diseases like diaria, gastro, some stomac , intestinal problem may causes due to polluted water

Contaminated water upsets the balance within us. It puts bacteria into our bodies and sometimes our bodies cannot fight it off. It depends on the bacteria introduced and the fighting power of our white blood cells in our bodies. Some people may get sicker that other ones. If our bodies are already compromised with an illness, then we're **** out of luck. Diarrhea and nausea and vomiting are big symptoms, then after that, dehydration. When there's dehydration, all kinds of things can happen because our cells do not, at that point, have the equipment to handle hardly anything.
