Question 1.
What does KOC stand for?
Show hintHide hint
Think about its relationship with organic carbon and water.
Question 2.
Explain hydrophobicity in simple terms.
Show hintHide hint
What do we call substances that do not mix with water well?
3Question 3.
What does KOC represent?
- A solubility measure
- A partition coefficient for organic carbon
- A type of pesticide
Show hintHide hint
Consider the definitions we discussed on partitioning.
4Question 4.
True or False: Variability in organic carbon does not affect KOC.
- True
- False
Show hintHide hint
Recall our discussions about sources of organic carbon.
Question 5.
You are tasked with developing a new chemical that has low hydrophobicity for use in pharmaceuticals. How would you approach the design based on what we learned?
Show hintHide hint
Think about the balance between being water-loving and targeting specific tissues.
Question 6.
If an experimental chemical shows a KOC value twice that of a known pollutant, what implications does this suggest regarding its environmental impact?
Show hintHide hint
Consider how binding to organic matter affects movement through ecosystems.
