Thermal pollution is a kind of physical environmental pollution. It is characterized by an increase in the temperature level, exceeding the natural natural level. Has a detrimental effect on the entire ecosystem.
As a result of the urbanization of many territories, a “thermal cap” has formed, which has a domed appearance. The main sources of this type of pollution are associated with emissions into the atmosphere of air heated to high temperatures. Also, emissions into water receivers of hot wastewater have a detrimental effect on the hydrosphere. The severity of thermal pollution is associated with the appearance of the greenhouse effect.
Types of impacts
The impact of thermal pollution extends to the hydrosphere, atmosphere and lithosphere. Let’s consider each of them in more detail:
Impact on the hydrosphere
The activity of all power plants is tied to the use of wastewater in order to cool condensers and turbines in them. Hot liquid from factories also gets into the water. For these reasons, the water temperature can rise by an average of 8 degrees Celsius.
Impact on the atmosphere
The functioning of large industrial complexes had a significant impact on the state of the atmosphere. The greatest influence is exerted by enterprises related to energy, metallurgy, oil refining and transport. As a result of their activity, gases enter the atmosphere, which warm up to 120 degrees Celsius. As a result, the air becomes hotter, and the vegetation and life near these areas is greatly suppressed.
Impact on soils
The main reason for the increase in the temperature level of the earth is the development of an underground communication system of industrial enterprises and houses.
It is necessary to carry out careful work to reduce the negative impact of industrial enterprises, since their impact leads to the disruption of the entire ecosystem.
Anthropogenic impact on the environment
Pollution of the hydrosphere leads to the complete degradation of underwater animals. Since the saturation of water with oxygen decreases with increasing temperature. In warm water, oxygen dissolves in very small doses and rather slowly. Also, as a result of emissions from industrial enterprises, a large amount of carbon dioxide and hydrogen sulfide accumulate in the water. Such conditions provoke the growth of blue-green algae, which are associated with water blooms. Their activity also inhibits the development of beneficial green algae that plankton feed on. Fish suffer the most in conditions of elevated temperatures, since it is extremely difficult for them to adapt to this environment.
Atmospheric pollution has led to the development of heat islands, where cloud formation intensifies, air moves vertically, precipitation increases and humidity rises. Local climate fluctuation is one of the hallmarks of thermal pollution.
Pollution of the lithosphere leads to the rapid development of heat-loving plant species that suppress all other species that are not adapted to sudden temperature changes. Under the negative impact of thermal pollution is life in the meadows, forests and suburbs of cities. The productivity of agricultural land is falling sharply.
