  4. 4. ● It's a modification of the water, generally caused by humans, whoIt's a modification of the water, generally caused by humans, who makes it unsuitable or dangerous for human consumption,makes it unsuitable or dangerous for human consumption, industry, agriculture, fisheries, recreation, animals, nature andindustry, agriculture, fisheries, recreation, animals, nature and everyday life.everyday life. ● This contamination can comes from natural sources such asThis contamination can comes from natural sources such as volcanic ash, but the biggest part comes from human activities.volcanic ash, but the biggest part comes from human activities.
  5. 5. ● Some sources of water pollution are natural. For example, mercury in the Earth's crust and the oceans produce pollution of natural way of these. ● The sources are very dispersed and don't cause high concentrations of pollution, except in some very specific places. The man-made pollution is more dangerous than the natural. ● Natural factors can't be easily controlled and can have a significant impact on the quality of a water source. The factors are, for example, the weather, fires, geology and microbiology and nutrient growth.
  6. 6. They are divided into isolated and not isolated.They are divided into isolated and not isolated. ·IsolatedIsolated: Those pollution sources are characterized by single or: Those pollution sources are characterized by single or discrete unloading, in which contaminants are flushed from a onlydiscrete unloading, in which contaminants are flushed from a only or confined geographical area. Are for example the unloading ofor confined geographical area. Are for example the unloading of domestic effluents, industrial effluents, spillages, etc.domestic effluents, industrial effluents, spillages, etc. ··Not isolated:Not isolated: Include diffuse sources of pollution and activitiesInclude diffuse sources of pollution and activities that cover a larger area, causing widespread groundwaterthat cover a larger area, causing widespread groundwater contamination, that's why are harder to control than the isolated.contamination, that's why are harder to control than the isolated. They are the originated from agriculture, urban drainage, etc.They are the originated from agriculture, urban drainage, etc.
  7. 7. ● Organic wastesOrganic wastes:: Set of organic waste created by humans,Set of organic waste created by humans, livestock, etc. When these wastes are in excess, the bacteriallivestock, etc. When these wastes are in excess, the bacterial proliferation depletes oxygen and makes it can't live living beingsproliferation depletes oxygen and makes it can't live living beings that need oxygen.that need oxygen. ● Inorganic Chemicals:Inorganic Chemicals: They're salts and toxic metals such asThey're salts and toxic metals such as mercury, lead and acids. They cause serious damages to livingmercury, lead and acids. They cause serious damages to living beings, reducing the agricultural yields and corroding thebeings, reducing the agricultural yields and corroding the equipment used to operate the water.equipment used to operate the water.
  8. 8. ● Organic compounds:Organic compounds: Organic molecules, like oil andOrganic molecules, like oil and detergents end up in the water and are, in many cases, longdetergents end up in the water and are, in many cases, long periods because they're products made by man with molecularperiods because they're products made by man with molecular structures difficult to degraded by microorganisms.structures difficult to degraded by microorganisms. ● Sediments and suspended materials:Sediments and suspended materials: Particles pulled outsParticles pulled outs from the ground and dragged into the water, along with materialsfrom the ground and dragged into the water, along with materials in suspension, are the major source of water pollution. Thein suspension, are the major source of water pollution. The turbidity that produce them, makes the life difficult of organisms,turbidity that produce them, makes the life difficult of organisms, and the accumulated sediment destroy spawning sites, filled lakesand the accumulated sediment destroy spawning sites, filled lakes or swamps, etc.or swamps, etc.
  9. 9. ● Radioactive substancesRadioactive substances:: Soluble radioactive isotopes can beSoluble radioactive isotopes can be in the water and sometimes they accumulate along food chains,in the water and sometimes they accumulate along food chains, reaching higher concentrations in some living tissues than theyreaching higher concentrations in some living tissues than they had in the water.had in the water. ● PathogensPathogens:: Kinds of bacteria, viruses and protozoa transmittedKinds of bacteria, viruses and protozoa transmitted diseases like cholera and typhoid. In LDC's the diseasesdiseases like cholera and typhoid. In LDC's the diseases producing by these are one of the reasons of death. Theseproducing by these are one of the reasons of death.

Chlorination plants also give rise totrout, accumulated them. Chlorination plants also give rise to phenols chlorine, which gives the water an unpleasant taste.phenols chlorine, which gives the water an unpleasant taste.
  11. 11. ● Heat-induced effects:Heat-induced effects: The main effect is the reduction ofThe main effect is the reduction of dissolved oxygen. And it can affect directly on aquatic animals. Ifdissolved oxygen. And it can affect directly on aquatic animals. If the temperature increase, also increase the speed of biologicalthe temperature increase, also increase the speed of biological reaction and the solubility of some compounds.reaction and the solubility of some compounds. ● Effects caused by organic matter:Effects caused by organic matter: Its effects are differentIts effects are different depending on whether is biodegradable organic matterdepending on whether is biodegradable organic matter (decreased dissolved oxygen) or is non-biodegradable (reduces(decreased dissolved oxygen) or is non-biodegradable (reduces self-purification capacity of a river).self-purification capacity of a river).
  12. 12. ● It is known that water pollution is a main source of illness;It is known that water pollution is a main source of illness; caused by bacteria transmitted by drinking water, used forcaused by bacteria transmitted by drinking water, used for various activities in the home. According to the Worldvarious activities in the home. According to the World Health Organization, 80% of infectious diseases are due toHealth Organization, 80% of infectious diseases are due to contaminated water.contaminated water.
