What is Thermal Pollution? [Cause, Effect & Control]

Thermal pollution results from the addition of heat to surface waters rivers, lakes, and oceans in an amount that creates adverse conditions for the survival of aquatic life Goudie, ; Pluhowski, As water warms up, its saturation values of dissolved oxygen decrease, the metabolism of aquatic life increases and more oxygen is used by these organisms. The rate of biochemical oxygen demand increases, resulting in oxygen depletion. Species of aquatic life change to less desirable forms for example, trout are replaced with catfish, diatoms are replaced with blue-green algae, which can cause taste and odor problems , eutrophication or the aging of this surface water is speeded up, and adverse effects of compounds toxic to fish and other aquatic life generally increase with rising temperature. Basically, thermal pollution makes the water less suitable for domestic, recreational and

However, thermal pollution is a real and persistent problem in our modern society. They then eject that water back into the natural resource, which changes the oxygen levels and can have disastrous effects on local ecosystems and communities. Thermal pollution is defined as a sudden increase or decrease in temperature of a natural body of water, which may be ocean, lake, river or pond by human influence. This normally occurs when a plant or facility takes in water from a natural resource and puts it back with an altered temperature. Usually, these facilities use it as a cooling method for their machinery or to help better produce their products.

When we heard the term pollution, then we think about the concepts like carbon emission, personal pollution, and waste. However, the thermal pollution is a real and persistent problem in modern industrialized society. The term thermal pollution has been used to indicate the detrimental effects of heated effluent discharge by various power plants. It denotes the impairment of quality and deterioration of aquatic and terrestrial environment by various industrial plants like thermal, atomic, nuclear, coal-fired plants, oil field generators, factories, and mills. The discharged effluents of these sources have a higher temperature than the intake water that reduces the concentration of oxygen from the water which causes the deleterious effects on the marine ecosystem.

Thermal Pollution: Effects, Causes and Control of Thermal Pollution | Speech

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. When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreases oxygen supply and affects ecosystem composition. Fish and other organisms adapted to particular temperature range can be killed by an abrupt change in water temperature either a rapid increase or decrease known as "thermal shock. Urban runoff — stormwater discharged to surface waters from roads and parking lots —can also be a source of elevated water temperatures.

What is Thermal Pollution?

Simply put, thermal pollution comes from hot water or cold water being dumped into a body of water. Bodies of water naturally tend to dissipate the heat gained from warm currents, underwater hot springs, and from the sun. Thermal pollution is called that because it overwhelms the natural temperature control mechanisms that work in the water. The sudden temperature change poses a health risk to a wide range of aquatic and amphibious creatures. This article is an overview of the problem, as it relates to water supplies.

What is Thermal Pollution?

This hot water is released into the system from where it was drawn, causing a warming trend of surface water. If the system is poorly flushed, a permanent increase in the temperature may result. It may bring other disturbance in the ecosystem. The egg of fish may hatch early or fail to hatch at all. Macro-phytic population may also be changed. As temperature is an important limiting factor, serious changes may be brought about even by a slight increase in temperature in a population.

Вирусы были самой большой неприятностью, с которой сталкивались в своей работе программисты. Поскольку компьютеры должны были выполнять операции в абсолютно точном порядке, самая мелкая ошибка могла иметь колоссальные последствия. Простая синтаксическая ошибка - если бы, например, программист по ошибке ввел вместо точки запятую - могла обрушить всю систему.

 Коммандер, - вмешалась Сьюзан, - я хотела бы поговорить… Стратмор жестом заставил ее замолчать. Глаза его неотрывно смотрели на Чатрукьяна. - В него попал зараженный файл, сэр. Я абсолютно в этом уверен.

Шедший сзади, метрах в десяти, Беккер смотрел на них, не веря своим глазам. Фотография внезапно обрела резкость, но он понимал, что увиденное слишком невероятно. Один шанс к миллиону. У меня галлюцинация. Когда двери автобуса открылись, молодые люди быстро вскочили внутрь.

    Thermal pollution also has some natural causes. Geothermal vents and hot springs introduce excess heat into bodies of water. Soil erosion, deforestation, and runoff from paved areas are other artificial sources of hot water. Deforestation eliminates shade, which exposes the water to sunlight.
