Question 1 of 5
1. Question
Hot water discharged by industries is considered as a water pollutant because
- Higher water temperature generally decreases the level of dissolved oxygen of water.
- High temperature limits oxygen dispersion into deeper waters, contributing to anaerobic conditions in deep water.
Which of the above statements is/are correct?
Correct
Solution: c)
Elevated temperature typically decreases the level of dissolved oxygen of water. This can harm aquatic animals such as fish, amphibians and other aquatic organisms.
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.
High temperature limits oxygen dispersion into deeper waters, contributing to anaerobic conditions. This can lead to increased bacteria levels when there is ample food supply. Many aquatic species will fail to reproduce at elevated temperatures.
