Question on: JAMB Chemistry - 2024
One of the following is not a water pollutant?
Water pollutants are substances that contaminate water bodies and make them unsafe for various uses.
A. Inorganic fertilizers: These contain chemicals like nitrates and phosphates that can cause eutrophication, leading to algal blooms and oxygen depletion in water bodies.
B. Warm water affluent: Thermal pollution, like warm water from industrial processes, can reduce the oxygen solubility in water and harm aquatic life.
C. Oxygen gas: Oxygen is essential for aquatic life and is naturally present in water. It is not a pollutant.
D. Biodegradable waste: Although biodegradable waste can deplete oxygen as it decomposes, leading to pollution, it is, by itself, not a pollutant, but the process it initiates can be considered a form of pollution. Therefore, the only substance listed that is not a water pollutant is oxygen gas.
