In the field of toxicology, understanding BOD is essential because it helps evaluate the impact of pollutants on aquatic ecosystems. High BOD levels indicate a high concentration of organic material, which can lead to oxygen depletion in water bodies. This condition is detrimental to aquatic life, causing stress or death to fish and other organisms. Furthermore, BOD can help identify the presence of toxic substances that may not be immediately detectable through chemical analysis alone.
