All types of water pollution are harmful to human and animal health. Water pollution may not harm our health immediately, but long-term exposure can be harmful. Different forms of pollution affect animal health in different ways:
- The heavy metals in industrial processes can accumulate in nearby lakes and rivers. It is toxic to fishes, crustaceans and other marine life, so it is also toxic to people who eat it. Heavy metals can delay development; it can cause birth defects, some of which are carcinogenic.
- Industrial waste often contains many toxic compounds that can harm the health of aquatic animals and edible aquatic animals. Some toxins in industrial waste may have only a mild effect, while others may be lethal. It can cause immunosuppression, reproductive failure or severe intoxication.
- Generally, bacterial sewage pollution causes infectious diseases, which affect water and land through drinking water. Microbial water pollution is a major problem in developing countries, and diseases such as cholera and typhus are the main causes of infant deaths.
Organic matter and nutrients cause an increase in aerobic algae and extract oxygen from the water column. Causes suffocation of fish and other aquatic life.
- The particulate material in fresh water reduces the quality of drinking water and the aquatic environment of marine life. Suspended particles can generally reduce the amount of sunlight that moves through the water, impairing the growth of plants and microorganisms.
Water pollution can hurt the economy, as treating and preventing pollution can be costly. Garbage that does not degrade quickly accumulates in the Earth's water and is eventually transported to the oceans.
Water pollution can be avoided by preventing pollutants from contaminating nearby waters. There are many water treatments to prevent pollution, such as:
Maintaining these simple techniques is expensive, but prevention work is much cheaper than cleaning up water pollution that has already occurred. The cost of cleaning up pollution depends on several factors:
- The contaminated area is important to determine the cleaning cost. If the pollution is in an easily accessible area, cleaning costs will be cheaper.
- Also consider the size of the contamination, the larger the contamination area, the more expensive the cleaning will be.
- The type of pollution also affects the cost of cleaning; some pollutants are more difficult to clean than others and therefore more expensive.
Please stop water pollution for better living of aquatic life.
