Water pollution is the addition of a foreign substance to water which makes it unfit for use.
Water pollution is not only caused by human practices, but it may also be natural.
Some natural causes include soil erosion, clay or silt runoff, and leaching.
Let's see the Sources and pollutants of water pollution
The sources of water pollution can be either point or particular, and non-point or dispersed.
Water pollutants include protozoa or viruses, chemical pollutants like mercury, and physical pollutants like sand or oil.
Microorganisms in water are very harmful to humans
Industrial effluents are a major source of water pollution. Industries do not treat their waste products and discharge them as is in nearby water bodies.
These effluents contain harmful chemicals, such as mercury, cadmium, and lead.
The discharge of chemicals into water bodies results in a loss of aquatic life.
The raised temperature of water bodies causes thermal pollution, which reduces dissolved oxygen content in water.
Let's now see the Effects of water pollution
Water pollution negatively impacts the quality of water in various ways.
It changes the physical characteristics of water. It tastes different, it possesses a bad odour, and in some cases, forms foam and sludge.
A number of lakes have gotten frothy with foam because of excessive water pollution.
water pollution also results in loss of aquatic life, due to harmful substances and lowered oxygen levels.
Industrial effluents that pollute water cause a variety of diseases, such as anaemia, and others.
Water pollution is the addition of any foreign substance to water that lowers its quality.
Water pollution is caused by industrial effluents, natural causes, and even hot water.
The effects of water pollution include changes in the characteristics of water, a variety of diseases, and a loss of aquatic wildlife.
