Water Pollution Effect: Thermal Pollution

You can easily observe that how heated-up water discharged from a power plant into a river cause severe problems for aquatic organisms. These aquatic living creatures are adapted to thrive in at a specific temperature. Hence,

industrial thermal pollution

is a big menace for the waterways – aquatic organisms like fish and others used to a specific temperature range may die because of thermal shock. Also, the additional heating may kill the young fish or disrupt spawning. Read on to know more about the harmful consequences of thermal pollution.

In addition,

warm water temperature may lower the dissolved oxygen

(DO) content of water. This creates a double trouble for the aquatic organisms as the warm water enhances their respiration rate. This results in faster consumption of oxygen. When all these conditions are combined together, they increase this organism’s susceptibility to the harmful effects of toxic chemicals, parasites, and diseases.

Thermal Heating due to Global Warming

This imparts an additional heating to the oceans. The oceans have absorbed nearly 20 times heat similarly to the atmosphere in the past half-century. It is a complex system and some of the effects of the “water pollution” include:

  • There will be a rise in the sea levels because of melting ice and thermal expansion. It will result in an increase in coastal flooding.
  • Occurence of more intense hurricanes due to gain in extra strength from warmer water surfaces.
  • Temperature-sensitive aquatic organisms will face tougher times such as corals. Temperatures in the tropical waters have increased by 1 degree Fahrenheit. This has adversely affected the corals in the form of coral bleaching.
  • The northward spread of a type of oyster pathogen is linked with the rise in the sea surface temperature in the eastern US. Cases similar to this incident is to occur more likely .
