Thermal Water Pollution
Thermal water pollution is the rise or fall in water temperatures. This changes in the temperature of water can be caused due to industries. Some industries use water as cooling agent, the heated water is let-off directly into the natural environment at a higher temperature. Cold water pollution happens when cold water is released into the water bodies. Aquatic organisms like fish are vulnerable to slight changes in the temperature. Heated water decreases oxygen in the water killing fish and other aquatic organisms. Cold water affects eggs and larvae, some invertebrates of the aquatic ecosystem.
