water pollution
water pollution
Definition
water pollution occur when harmful substances offten chemical or contaminate a steam, river lake or other body of water and rendering it toxic to humans or the environment. the widespread problem of the water pollution is endanger our health. unsafe water pollution kills more people each year than war and all second forms of violence combined.
water pollution permeable to pollution. known as "universal solvent", water is able to dissolve more substances than any other liquid on earth.water Pollution Discharge of domestic industrial affluent wastes, leakage from water tanks, marine dumping, radio active waste and at deposition are major causes of water pollution. Heavy metals that disposed off and industrial waste can accumulate in lakes and river proving harmful to humans and animal. Philadelphia has Sewer system a combin that is one pipe is used to carry both sewage and storm water.
Types of Water pollution
- nutrients pollution
- surface water pollution
- ground water pollution
- chemical water pollution
- oil spillage
- suspended matter
Types of Water Pollution
As water comes from many source there are many types of water pollution. The most common type of water pollution are described below.
- Agricultural/Nutrients Pollution
Some of the waste water and agricultural waste contain high nutrients level. These nutrient-rich contaminants cause algae growth, making the water unfit for drinking and other purposed. Algae use the oxygen content in water making oxygen scarce for other organism resulting in their death.
- Sewage and Waste Water
Sewage and waste water from urban settlement is rich in various soluble and non-soluble impurities like mercury, plastic, rotten foods, debris, chemicals. When these pollutant reach water bodies, some of them float over the surface while some sink at the bottom. The soluble impurity change the composition of water as well. This is a dangerous situations for all the living organism in the water body.
- Oxygen Depletion
Any water body contains several microorganism including aerobic and ana When the biodegradable waste reaches into the water bodie and decays.it encourages the growth of more microorganism consequently using more oxygen in the turn depleting the oxygen level.
Effects of Water Pollution
contamination of water by several human activites.when toxic compounds get introduced in water they render it harmful to health or dangerous for life.
- around of the world waste water produced annually is dumped directly into our water bodies without even get treaded.
- unclean and contaminated water claims more lives annually than water other diseases.
- human generated pollution ore uses of water.
- Dumping industrial waster, urban sewage,oil spills,fossil fuel production and burning, leaked sewer lines, littering at public place, etc.
- water pollution is the major threat to the environment as wall as to the life of species.
- It affect everyone and is severely damaging the ecological balance.
- It is extremely necessary that we take the necessary step to prevent.
It can happen when people throw garbage into the water.Chemicals from factories can also cause water pollution. Pollution can make the water dirty and unsafe for animals and plants.Trash in the water can harm animals that live there. water can make peoples sick if they drink it or swim in the water can make people sick if they Pollution can kill fish and other creatures that live in the water.
It is important to keep our water clean and free from pollution.People can help by not throwing trash into rivers or lakes.We can also use fewer chemicals and recycle to reduce water pollution.
Effects of Water Pollution
Ground water contamination from pesticide causes reproductive damage with in wild life in ecosystem.Sewage, fertilizer, and agricultural run-off contain organic material that when discharged into waters, increase the growth of algae, which causes the depletion of oxygen. The low oxygen level are not able to support most indigenous organisms in the area and therefore upset the natural ecological balance in rivers and lakes.Human produced litter of item such as the plastic bags and 6-pack rings can get aquatic animals caught and killed from suffocation.Water pollution causes flooding due to the accumulation of solid waste and soil erosion in streams and rivers.Oil spill in the water causes animals to die when they ingest it or encounter. Oil does not dissolve in water so it causes suffocation in fishs and birds.
water pollution and effect on human health
water pollution is the fouling oceans,seas, lakes rivers and ground water.This is usually cased due to human to human activite. water pollution changes in the physical,chemical or biological properties of water that will have a detrimental consequence of any living organism. water pollution can be classified as surface water pollution or ground water pollution. marine pollution and nutrient pollution are sub set of water pollution. sources of water pollution are either point source. so, what is point source and non point source. a point source is the single definable source of pollution but a non point of source is the multiple of pollution where is orginate.
