Challenge Problems
Push your limits with advanced challenges
You have a sample with an initial DO of 8.0 mg/L and a final DO of 0.0 mg/L with a dilution factor of 10. Calculate the BOD and discuss the implications of a BOD this high for water quality.
💡 Hint: Consider the relationship between BOD levels and environmental health.
A lab mistakenly tests BOD at a temperature of 30°C instead of 20°C. How would this affect the results, and what should be done for accurate readings?
💡 Hint: Reflect on how temperature impacts microbial activity.
