1.5. Log KOC and its Implications

Try these first

1. 1.

   What does KOC stand for?

   Hint

   Think about chemical interactions.

2. 2.

   Why do we use log KOC instead of KOC?

   Hint

   Consider the math behind logs.

3. 3.

   What does KOC represent?

   • Partitioning between soil and air
   • Partitioning between organic carbon and water
   • Partitioning between gas and liquid

   Hint

   Focus on the elements specified in the term.

4. 4.

   Log KOC is used because it:

   • True
   • False

   Hint

   Think about the advantages of logarithmic scales.

5. 5.

   You have a chemical with a KOC of 10^5. Discuss the environmental implications of high KOC values on pollutant behavior.

   Hint

   Consider how pollutants accumulate in ecosystems.

6. 6.

   Propose a method to determine the KOW of a new pharmacological agent and relate it to its potential bioaccumulation effect.

   Hint

   Linking the method to the principles discussed in relation to KOC.
