Challenge Problems

Push your limits with challenges.

Question 1

A chemical has a KOC value of 10,000. If the concentration of this chemical in the water is 1 mg/L, what would the concentration of the chemical likely be in organic carbon?

💡 Hint: Use the definition of KOC to rearrange the equation.

Question 2

Compare the implications of a chemical with a KOC of 2000 versus one with a KOC of 500 in an environmental cleanup scenario. Which one poses greater risks for bioaccumulation and why?

💡 Hint: Evaluate how KOC values relate to chemical behavior in the environment.
