Thermal pollution is a type of water pollution that occurs when the temperature of a body of water is artificially increased. This can have a range of negative effects on aquatic life, including changes to the physical and chemical properties of the water, alteration of the behavior and metabolism of organisms, and harm to individual species and ecosystems.
One of the primary ways that thermal pollution occurs is through the discharge of hot water or steam from industrial processes, such as power plants and factories. This hot water can raise the temperature of the receiving body of water, causing it to exceed the optimal range for many aquatic species. When the temperature of a body of water increases, it can cause changes in the solubility of gases and the density of the water, which can affect the distribution and abundance of species.
Thermal pollution can also alter the behavior and metabolism of aquatic organisms. Many species have evolved to thrive within a specific temperature range, and changes in temperature can cause them to become stressed or to migrate to different areas. In some cases, thermal pollution can also cause changes in the reproductive success of certain species, leading to population declines.
In addition to the direct effects on individual species, thermal pollution can also have broader impacts on aquatic ecosystems. Changes in temperature can alter the balance of predator and prey populations, leading to shifts in the structure and function of entire communities. This can have cascading effects on the entire ecosystem, leading to declines in biodiversity and changes in the ecosystem services that it provides.
Thermal pollution can also have negative impacts on human activities and industries that rely on healthy aquatic ecosystems. For example, changes in the distribution and abundance of fish and other aquatic species can affect commercial and recreational fishing, as well as industries that rely on healthy water resources, such as agriculture and tourism.
Overall, thermal pollution has the potential to cause a range of negative effects on aquatic life and ecosystems. To mitigate these impacts, it is important to reduce the amount of thermal pollution being introduced into bodies of water, through measures such as better regulation of industrial discharges and the adoption of more efficient and environmentally friendly technologies.
What are the effects of thermal pollution on aquatic life?
Furthermore, these water pollutant can also be natural or synthetic. Share this: Facebook Facebook logo Twitter Twitter logo Reddit Reddit logo LinkedIn LinkedIn logo WhatsApp WhatsApp logo The pollution is the biological, chemical or physical alteration of the water, land, or air that is harmful to living organisms, ocean waters and surface waters. Copy to Clipboard Reference Copied to Clipboard. Excess heat can confuse animals' ability to determine season and even direction. That peak level may already imply that they have become pollutants already. Copy to Clipboard Reference Copied to Clipboard.
Also, increased water temperatures can change the pattern of spawning, reproduction and fish migration. The temperature changing harms the fish and other aquatic organisms in many ways. Countries have definitely been talking and dealing about it together as one. Food Scarcity: Unfavorable temperatures may cause food scarcity in the affected water bodies. An abrupt change in the temperature of a natural body of water causes the oxygen level in the water to diminish. Additionally, this effect can either be lethal or sublethal. These reactors are made by 4 major manufacturers.
The Effects of Thermal Pollution on the Aquatic Life in the Southern Marshes of Iraq
There are 437 nuclear power plants are in operation and 55 are under construction worldwide. The Oyster Creek Nuclear Generation Station OCNGS is oldest operating nuclear power plant in United States, which is located in Forked River in the Lacey Township, in New Jersey. The temperature changing harms the fish and other aquatic organisms in many ways. This plant has producing capacity of 1059 MWe, and in 2007 it has produced 8104 GW-h, where it has average of 7528 GW-h in last 5 years of energy production. Our planet Earth is unique in every aspect. Malnourishment in marine life: The lack of food diversity in the ecosystem will lead to malnourishment since thermal pollution diminishes the food web. The pesticides like DDT and PCBS can enter the oceans through city waste water and industrial discharges from farms and forests.
Their shell length ranges from 36-43 inches and weights average between 200-300 pounds. There are the pathogenic bacteria, coliforms, and faecal streptococci. It can adversely affect mortality and reproduction of the organisms. Effects Of Thermal Pollution On Aquatic Species. When thermal pollution continues for a long time, it gradually affects the reproductive systems of the organisms. In: Barnes JR, Minshall GW eds Stream Ecology.
Lastly, they can be lethal which is sudden death by direct intoxication. As of the Harold Haines and William Kleese, the scientist from the Miami, Florida, proved that the role of water temperature in the induction and maintenance of a dermal herpes virus infection gray-patch disease of young, green sea turtles, which influence of other recognized stress factors were negligible. They have very few natural predators, like sharks, crocodiles and alligators over time to time. The effects of the elevated water temperatures and residual chlorine at a coastal nuclear power plant on the biomass and productivity or periphyton and phytoplankton, but not productivity was significantly lower in the outlet region than in the intake region. Like any other form of water pollution, thermal pollution is widespread affecting many lakes and the vast numbers of streams and rivers in various parts of the world. It changes when water is used in industrial and power plants as a coolant.

In comparison to other sources, 1,000 MWe reactors has 90% of amount of electricity has generated in 1 year. Figure : Hope Creek Nuclear Generating Station. This plant is called Watts Bar 1, which is located in the spring city, and the capacity for generation if 1,123 MW. The Cyanobacteria is also the blue-green algae. Read also Effects Of Improper Waste Management Environmental Sciences Essay The nuclear reactor is a device to initiate, control and sustain a nuclear chain reaction. There are 32 companies which are licensed to operate the nuclear reactors in United States. But they have gotten 3500 acres of wetlands for restoration for fall back option as the alternative way.
This can either be caused by excessive plant nutrients or physical pollutants. On the other hand, unicellular green algae need nitrate. It is caused by either dumping hot water from the factories and power plants or removing trees and vegetation that provide shade to streams, permitting sunlight to raise the temperature of these waters and release cold water which lowers the temperature. This reduces biodiversity given the interdependence that exists among members of a given ecosystem. From 1990s to 2000s there have been 4 other plants have been built, which are in August 1993, the Comanche Peak 2 with capacity of 1,158 MW and in 1990, the Comanche Peak 1, with capacity of 1,209 MW. Major sources of thermal pollution — Power plants create electricity for fossil fuels. The New Jersey has been ranked 10th in nuclear capacity and 9th place in nuclear generation in 2008.
There are 32 companies which are licensed to operate the nuclear reactors in United States. A threat to biodiversity: Since many of the living organisms found in these water bodies will be affected by the sharp temperature changes. It is with low, broadly oval carapace and small head with one pair of pre frontal scales that are unique to them. The plant intakes and discharges 1. For the pressurized water reactors, 15 of them are one reactor, 24 of them are two reactors and 2 of them have three reactors. They had failed to turn off the dilution pumps during emergency shut-downs and allowing millions of gallons of the hot water to enter the creek and bay.
The unit 1 is licensed to operate until August, 2016 and unit 2 is licensed to operate until April, 2020. Thermal pollution may also increase the metabolic rate of aquatic animals, as enzyme activity, resulting in these organisms consuming more food in a shorter time than if their environment were not changed. The most common and well-studied form in water is effluent from power-plant cooling systems, but it may also be caused or enhanced by erosion, loss of forest cover, or eutrophication -- anything that changes a body of water's capacity to absorb light and heat. As discussed, temperature fluctuations can also have negative impacts on organisms that live in water. As discussed, temperature fluctuations can also have negative impacts on organisms that live in water. Two of the power stations are called Salem Nuclear Power Plants, which are pressurized water reactor nuclear power station and the other one is called a Hope Creek Nuclear Generating Station, which is a thermal nuclear power plant. Fish, plankton and benthos are all affected at various degrees by thermal discharges from power plants.
For this reason, we have to solve it. Additionally, know that the major polluting effect of these materials is that they reduce the oxygen in the water. How does the water quality change? They evolved more than 150 million years ago, and they spend entire lives in the sea, even more then come to the surface to breathe, and remain underwater for several hours for resting. Increased metabolic rate: An increased metabolic rate means that marine animals will expend a lot of energy while accomplishing very simple tasks. The Thermal discharges of unused heat from fossil fuel or from fission in the nuclear fuel constitute another kind of environmental impact.
