Download - Land pollution and Thermal Pollution
Thermal / Heat Pollution
Is the act of altering the temperature of a natural water body, which may be a river, lake
or ocean environment. This condition chiefly arises from the
waste heat generated by an industrial process.
Thermal / Heat Pollution
Major Sources of Thermal pollution
Fossil-fueled electric power plants
Nuclear-fueled electric power-generating facilities
Cooling operations associated with industrial manufacturing
Earth’s surface temperature
Carbon Dioxide as product of combustion adding to the greenhouse gases
Hot water vapor
Effects of Thermal Pollution
Ecological imbalance resulting in major fish kills near the discharge
source
Accelerates chemical-biological
processes
Decreases the ability of the water to hold
dissolved oxygen
Thermal changes affect the aquatic system by
limiting or changing the type of fish that grow and reproduce in water
Contributes to greenhouse effect that
results in global warming
