The various causes of pollution are as follows:. Control of pollution is important as its prejudicious effects on an aquatic system could also be prejudicious within the future. Viable solutions to chronic thermal discharge into water bodies are explained below:. Along with this, below are the preventive measures to control thermal pollution:. This causes increased amount of garbage and junk in the water bodies leading to increased water temperature.
Give your memorable thermal pollution presentation and build your crawd. When the water used for cooling comes back to the natural environment, its temperature is high. Get the plugin now. Published by Reynold Morton Modified over 4 years ago. Tropical marine animals are generally unable to withstand a temperature increase of 2 to 30C and most sponges, mollusks and crustaceans are eliminated at temperatures above C.
When a power plant first opens or shuts down for repair or other causes, fish and other organisms adapted to particular temperature range can be killed by the abrupt rise in water temperature known as 'thermal shock'.
The decrease in levels of DO can harm aquatic animals such as fish and amphibians. 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. In Australia, where many rivers have warmer temperature regimes, native fish species have been eliminated, and macro invertebrate fauna have been drastically altered and impoverished. As a result one has the problem of compromising food chains of the old and new environments.
As a result Biodiversity can be decreased. Releases of unnaturally cold water from reservoirs can dramatically change the fish and macro invertebrate fauna of rivers, and reduce river productivity. Increase in toxicity: The rising temperature changes the physical and chemical properties of water. A C rise in temperature doubles the toxic effect of potassium cyanide. Jesa Bayoneta.

No notes for slide. Thermal pollution 1. When a power plant first opens or shuts down for repair or other causes, fish and other organisms adapted to particular temperature range can be killed by the abrupt change in water temperature known as "thermal shock. People often remove this shading vegetation in order to harvest the wood in the trees, to make room for crops, or to construct buildings, roads, and other structures.
