Water is a type of liquid compound. The combined flow of hydrogen and oxygen. Water has no colour, water has no odour, water has no taste. That is, water is a colourless, tasteless, odourless liquid. The water itself has no size and volume.

 water pollution:

Water pollution is generally what we understand when water becomes inadequate. Water becomes contaminated for various reasons and using these contaminated water can lead to various problems. For various reasons, water has become contaminated with the sea, if any, canal bills, wells, tube wells, ponds and various reservoirs.

Whenever harmful substances such as sewage, toxic, chemicals, silt, etc., get mixed with water. The water becomes polluted. The substance that pollutes water is called water pollutions.

 Causes of water pollution: -

The main source of pollutants that mix with water to pollute the reservoirs around us is char, In the field of art, farming, municipality etc. The organic, inorganic and radioactive substances generated from these sources are pollutants The substance is mixed with water in large quantities and added to it is thermal durability.

Some of the pollutants we know are waste materials, such as food, Human excreta, soap and detergents, including humans Fertilizers, pesticides, pesticides, weeds etc. used in agriculture.

In our daily life, the use of soap and detergent, Also known in the industry in small quantities and in large quantities of detergents Used for cleaning. But soap or detergent can no longer be used dry. The only need for that is water.

Soap comes mainly from affection as a pollutant for water Fatty acids, glycerin, fertilizers, etc., and various lubricants and dirt after cleaning, Detergent comes from the addition of sulfate, Cellulose, sodium carbonate, and dirt after cleaning. Pollutants from soap and detergents do not dissolve in water Creates emulsions that have a detrimental effect on the life of aquatic animals and plants.

Oxygen is absorbed by the presence of lubricants on top of the water. As a result, the demand for oxygen in the water decreases. Again, sulfate and nitrated additives, Helps to grow faster, such as yolk and weed. As a result, weeds of the reservoir grow and some of them die and accumulate under the water. As a result, the depth of the reservoir gradually decreases and at one time it becomes fun. This phenomenon is called eutrophication.

Water is another important cause of chemicals used in agriculture. Two or three times a year to get a crop or to increase crop yields Farmers use a variety of fertilizers, pesticides, weeds, etc. All these chemicals take small amounts for the crop.

Most chemicals, fertilizers and pesticides are washed in irrigation water and in rainwater, in nearby reservoirs, After going to the river. As a result, those reservoirs are contaminated with water.

The nutrient content of the water increases if the seawater contains excessive amounts of chemical fertilizers and GB waste wastes. As a result, the number of phytoplankton in the water increases. Once the seawater is mixed with high levels of watercolour becomes green or red colour. This is called agalgalbrum.

Wall brook is in the water When dissolved, the amount of oxygen is reduced and taken from their bodies Differentiation can also lead to the death of other organisms. 

The harmful effects of pollution on public life: -

Pollution reduces the demand for oxygen in the water. As a result, the aquatic organisms have difficulty in breathing.

Due to eutrophication, many reservoirs will be fun to catch.

Various diseases are infected as a result of water leakage. Many times a disease takes the form of an epidemic. Water pollution causes various diseases. They are cholera, typhoid, diarrhoea, asthma, mechanical, hepatitis, skin disease etc.

Groundwater arsenic and fluoride contamination: -

The pesticides, pesticides, or fungicides that farmers use include arsenic, Calcium arsenate, sodium arsenite, copper isocyanate, Paris green etc. Again, gold or lead units and coal also contain arsenic. All these arsenic compounds are contaminated with water.

Metal Arsenic whose vacuum is zero, our stomach and intestines are not absorbed. As a result, it does not harm us. But arsenic in nature has its arsenate or arsenite compound, Poisoning occurs in our bodies.

Arsenic contamination: -

If the arsenic level in the water exceeds the maximum, then the water is called arsenic contamination. WHO According to this, the safe level of arsenic in water 0.1 mg/l.

Effect of arsenic contamination: -

Drinking arsenic water for longer than six months causes arsenic-related disease. Infected with this disease is inflammation of the lungs, mouth sores, The eyes turn red. Sore spots on the palms and feet of the hands. It's called Blackfoot. Arsenic poisoning can lead to cancer.

Remedy: -
The use of arsenic-associated pesticides, weeds and pesticides should be stopped. The arsenic of the byproduct must be reduced to drain the metal So as not to touch the soil. Arsenic Purification Plant must be provided with arsenic-free water by fitting with a tube well.  Currently, water is released from arsenate and arsenite using ion exchange resins.

Fluoride contamination: -
If the presence of fluoride in drinking water exceeds the optimum level, the water is called fluoride contamination. If the water 1.0mg/l  Fluoride is saturated, but that water is ineligible.

Effect of Fluoride Pollution: -
 Fluorosis is a disease caused by water fluoride contamination. The extra fluoride tooth enamel turns white to yellow or black. Besides, symptoms of physical disorders, instability, lungs, etc. are also manifest.

Remedy: -
Groundwater contains high levels of arsenic and various types of metallic fluoride, which enter the body through tap water and well water. Therefore, the use of groundwater is discontinued  The amount of fluorosis consumed in the water of the wells or tubes will be very low in the sense.
