Challenge Problems
Push your limits with advanced challenges
You are tasked with measuring the concentration of pollutants in a river. Describe the steps you would take to ensure reliable data collection considering sample volume and detection limits.
💡 Hint: Think critically about how to avoid being below the detection limit.
