Answer:
A high COD to BOD ratio indicates that the organic pollutant has relatively little organic materials that it can oxidise.
Explanation:
- This ratio is usually greater than one, however it can be one if the sample only contains biodegradable organics.
- The overall assessment of all compounds in the water that can be oxidised is known as chemical oxygen demand (COD).
- The amount of food (or organic carbon) that bacteria can oxidise is supposed to be measured by biochemical oxygen demand (BOD).
