\nThe release of excessive heated water into aquatic systems causes thermal pollution, which is harmful because hot water holds less dissolved oxygen compared to cold water, leading to oxygen starvation for aquatic organisms.
\n<\/section>\n
\n– Solubility of gases in water decreases as temperature increases. Therefore, less oxygen can dissolve in hot water.
\n– Higher water temperatures increase the metabolic rates of fish and other aquatic organisms, which increases their demand for oxygen.
\n– The combined effect of reduced oxygen availability and increased oxygen demand can lead to stress, suffocation, and death of aquatic life.
\n<\/section>\n
\n– Thermal pollution can also affect the reproduction, growth, and behavior of aquatic species.
\n– It can alter species composition, favoring tolerant species and eliminating sensitive ones.
\n– Sources of thermal pollution often include cooling water discharges from power plants, industrial facilities, and urban runoff.
