Water pollution is defined as when many toxic chemicals are added into the water the water is polluted. A small drop of harmful chemical in a house pump or cannel can polluted the water in heavy amount. This can be much harmful for human. While a large amount, a chemical in a river can pollute low water. “Any change or modification in the physical, chemical and biological properties of water that will have a detrimental consequence on living things is water pollution.” Water pollution affects the drinking water, lakes, rivers and all over the world.
There are several types of water pollutants; one category is the microbiological, which refers to the contamination of viruses and bacteria in water. Another category is nutrient pollution, which is caused by excessive amount of nutrients in water supplies, making it undrinkable. Chemical water pollution refers to the chemical compounds that end up in water supplies. Many industries contaminate water with toxic or radioactive materials and sometimes use rivers and lakes to dispose of waste heat, resulting in thermal pollution. Water quality is threatened by many sources, besides fecal matter, water is exposed to many toxic substances.
People have been abusing and misusing water since long. There are many factors which cause river contamination and there are also many effects of river contamination to us. Let me to tell you further about the causes and effects of river pollution. First, disposing industrial wastes into rivers by irresponsible people is a factor which causes river pollution. Industrial wastes are especially harmful and they are containing large amount of toxic chemicals.
In addition, reckless individuals are too selfish to spend their time to properly dispose of their waste material. Enough research has been done to prove that sewage contains many kinds of hazardous chemicals, from pharmaceuticals to papers and plastics which are harmful to the environment, wildlife, and humans. What’s more, the sewage carries viruses into water systems such as cholera and typhoid that leads to sickness towards any living creature. Due to the excessive amount of waste that the environment cannot deal with, it acts as the food source for algae, which develops wildly. Not only, algae will take the oxygen out of the water and increase carbon dioxide in which the marine life cannot survive, but also it creates the outlets of a toxin to enter the food chain and harm individuals who consume
It occurs unpleasant sound stirs our ears and results to psychological problems such as stress, hypertension, hearing impairment, etc. The primary causes of soil pollution are loud music and industrial noises. Radioactive pollution, though rear, is the most dangerous form of pollution when it occurs. It can be caused by nuclear plant malfunctions, accidents, improper nuclear waste disposal, etc. most of its effects are a severe and long term in nature and include defects at the time of birth infertility, blindness, cancer, can affect air and water as well as sterilizing
So as I said before all of the above are provoked by us. Lets talk about sewage, in our houses the production of wastewater can cause pollution in lakes and rivers because it often contains faeces, urine and laundry waste. Our second point is marine dumping which can cause several issues specially to marine life; items such as 6-pack ring packaging can get caught in animals and as a result death. Other things that can cause problems are Newspaper; which takes 6 weeks to degrade,
This is due to their carcinogenic and toxic properties (ATSDR, 2013). As the strict legislations have been introduced by various environmental protection agencies in the developing countries, the removal of heavy metals from water and wastewater becomes the subject of considerable interest in recent years (CPCB, 2008; WHO, 1996). Manganese, nickel and copper are the common heavy metal contaminants and pose significant threats to human health. Manganese poisoning causes various severe health problems in vital organs of humans such as neurological disorders and harmful impact on human respiratory tract due to prolonged inhalation of Mn(II) (ATSDR, 2012). Gastrointestinal distress, pulmonary fibrosis and skin dermatitis are the most noted diseases in addition to lung and kidney problems associated with Ni(II) ion poisoning (ATSDR, 2005; US EPA, 1986).
Environmental pollution through the discharge of toxic heavy metal ions considered one of the most important issues that threat all biological systems including human, animal and plant kingdoms. For this reason, several attempts have been made for effective removal of these metal ions, particularly from industrial wastewater [1, 2]. As a pollutant, mercury (Hg) regarded as an extremely poisonous heavy metal with enormous harmful effect on our health . Numerous studies confirmed that sever medical diseases could be related to long term exposure to Hg2+ ions. Mercuric ions biomethylation could retain in blood and continuously deposit in some organs like kidneys, liver or brain and consequently cause chronic diseases ended with death [4, 5].
EFFECT The effects on the city and water supply have been enormous.To start with, the means of water supply have been transformed into open sewers. The consequence of people using water canals to clean their clothes is that the detergent used has spread. The detergent cannot dissolve due to the concentration of chemicals in the already contaminated water, and spreads throughout the canal and kills fishes and other living organisms. As for the waste produced by industries and factories, lots of this waste contains heavy metals: when it is dumped into the open canals, these toxic, poisonous metals are dumped along with it. One of the most toxic metals is mercury, which can have very serious side effects if ingested in excess, including paralysis, liver and kidney failure, and death.
The ecosystem is suffering from the water use in various industrial processes that comes from the toxic chemical and also from heavy metals and even the radioactive sludge, when they use these kind of mineral they polluted the water because it thrown into the ocean or maybe other water bodies without any treatment, so this process is bad and unhealthy for human and agricultural use ! . The second effect is really a horrible, believe it or not ! It can be on the water for many decades!! , the radioactive sludge at the bottom of the water bodies can remain a highly radioactive , so this process can lead to a serious health risk for people living nearby.
