described the factor responsible for degradation of water
Answers
Answer:
Factors responsible for degradation of water:
Sewage and Waste water:
The sewage and waste water has pathogens, heavy metals, toxic wastes, worm like parasites, oils etc,.
The sewage waters are collected from the pipes of homes into cesspits or septic tanks.
These water are mixed with rivers, lakes and those water on rivers and lakes get contaminated.
Industrial waste:
The waste from industries have substances having the suspended or dissolved in water.
After treatment, the industrial wastewate will be released to the sanitary sewer in the environment.
Chemical fertilizers and pesticides:
The chemical fertilizers that used in the agricultural lands, the stormwater pollutants which can easily degrade the quality of water.
At the time of raining, these nutients will flow with the rain water. And the nutrients can cause the growth of algae, so the oxygen will be easily used by those alage.
Marine dumping :
The garbage which produced by the household activities in the form of the rubber, plastic, paper, aluminum, glass, food. These are collected and deposited in the sea from some of the countries.

Answer:
Explanation:
Water bodies e.g. lake, river, ocean and ground water get contaminated due to discharge of pollutants in the water bodies without any treatment to remove harmful compounds.
Water pollution adversely affects not only aquatic plants and animals but it also affects human beings and ecosystems.
Causes of Water Pollution
Water pollution is caused due to several reasons. Here are the few major causes of water pollution:
Sewage And Waste Water: Sewage, garbage and liquid waste of households, agricultural lands and factories are discharged into lakes and rivers. These wastes contain harmful chemicals and toxins which make the water poisonous for aquatic animals and plants.
Dumping: Dumping of solid wastes and litters in water bodies causes huge problems. Litters include glass, plastic, aluminum, styrofoam etc. Different things take different amount of time to degrade in water. They affect aquatic plants and animals.
Industrial Waste: Industrial waste contains pollutants like asbestos, lead, mercury and petrochemicals which are extremely harmful to both people and environment. Industrial waste is discharged into lakes and rivers by using fresh water making the water contaminated.
Oil Pollution: Sea water gets polluted due to oil spilled from ships and tankers while traveling. The spilled oil does not dissolve in water and forms a thick sludge polluting the water.
Acid Rain: Acid rain is pollution of water caused by air pollution. When the acidic particles caused by air pollution in the atmosphere mix with water vapor, it results in acid rain.
Global Warming: Due to global warming, there is an increase in water temperature. This increase in temperature results in death of aquatic plants and animals. This also results in bleaching of coral reefs in water.
Eutrophication: Eutrophication is an increased level of nutrients in water bodies. This results in bloom of algae in water. It also depletes the oxygen in water, which negatively affects fish and other aquatic animal population.
Hope this helps.
