TYPES OF POLLUTION

 When you think of environmental pollution, it typically comes in seven different types. These include air, water, land, radioactive, thermal, light, and sound pollution. 

We will look into each of these: 

1. Air Pollution

Air pollution is when noxious gases and chemicals get suspended in air.

A major source of air pollution results from the burning of fossil fuels. Vehicle and factory emissions are common sources of this type of air pollution. The burning of fossil fuels contributes to the formation of smog, a dense layer of particulate matter that hangs like a cloud over many major cities and industrial zones. 

Air pollution contributes to respiratory problems such as asthma, lung cancer, chronic bronchitis, and other lung ailments. Nitrogen and sulfur oxides in the air contribute to acid rain, which is a form of precipitation with a lower (more acidic) pH than normal. Acid rain harms forests, species that live in water bodies, and degrades outdoor statues, monuments, and buildings.

2, Water Pollution

Water pollution does not only affect fish and other marine life, when pollutants get into the water, they have a devastating effect on the water cycle. 

Natural causes of water pollution include algae blooms and volcanoes. However, humans also cause water pollution through trash and wastewater from factories. 

A major source of water pollution is runoff from agricultural fields, industrial sites, or urban areas. Runoff disrupts the water body's natural balance. For example, agricultural runoff typically includes fertilizer or toxic chemicals. Fertilizer can cause algal blooms (an explosive growth of algae), choking out other plants and decreasing the amount of available oxygen necessary for the survival of other species. 

Raw sewage is another type of water pollutant. When sewage gets into the drinking water supply, serious stomach and digestive issues may result, including the spread of diseases such as typhoid or dysentery. 

A third source of water pollution is trash. Improperly disposed of items, such as plastic bags, fishing line, and other materials may accumulate in the water and lead to the premature death of animals that get tangled within the garbage.

3. Land Pollution

Land pollution is another one of the big three pollution types affecting the human population. Land pollution happens when the soil gets contaminated by fertilizers or chemicals being dumped. The pollution in the land can seep into the ground water or run into lakes and streams creating a vicious pollution cycle. 

Soil can become polluted by industrial sources or the improper disposal of toxic chemical substances. Common sources of soil pollution include asbestos, lead, PCBs, and overuse of pesticides/herbicides.

4. Noise Pollution

Noise pollution is caused by loud noises that can hurt the human ears. Types of noise pollution can include explosions, jet engines, and even concerts (if you are close to the speakers). 

Noise pollution is dangerous because it can cause hearing loss. This type of pollution has been shown to impact the movement of sea mammals, such as dolphins and whales and also impacts the nesting success of birds.

5. Light Pollution

Light pollution refers to the large amount of light produced by most urban and other heavily-populated areas. 

While lights are great for helping us to see at night, too many lights cause light pollution blocking out the night sky. Light pollution prevents citizens from seeing features of the night sky and has also been shown to impede the migration patterns of birds and the activities of nocturnal animals.

6. Radioactive Pollution

The radioactive pollution is defined as the physical pollution of living organisms and their environment as a result of release of radioactive substances into the environment during nuclear explosions and testing of nuclear weapons, nuclear weapon production and decommissioning, mining of radioactive ores, handling and disposal of radioactive waste, and accidents at nuclear power plants. 

7.Thermal Pollution

Thermal pollution, sometimes called "thermal enrichment," is the degradation of water quality by any process that changes ambient water temperature. 

A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. Thermal pollution can also be caused by natural forces like soil erosion giving water more sunlight. 

In conclusion we share a comment about pollution by one of our social media followers:

Air pollution, noise pollution, etc.. Affecting air by production of dangerous fumes to air and also having uncontrollable noise to humanity from machines for example
