6.1. Effects of Organic Matter on Partitioning

Try these first

1. 1.

   What is a partition constant?

   Hint

   Think of it as a measure of preference.

2. 2.

   Define aqueous solubility in simple terms.

   Hint

   What does it mean for something to be soluble?

3. 3.

   What does a partition constant represent?

   • Chemical preference between air and water
   • Equilibrium concentration ratio between two phases
   • Rate of chemical reaction

   Hint

   Think about its definition in terms of ratios.

4. 4.

   True or False: Higher organic matter in soil increases the partitioning of organic chemicals.

   • True
   • False

   Hint

   Recall how organic materials interact with pollutants.

5. 5.

   A researcher observes that a specific organic pollutant accumulates more in forested soil than in sandy soil. Discuss how the properties of these soils contribute to this observation.

   Hint

   Reflect on the nature of organic matter and its interactions.

6. 6.

   Describe a potential environmental disaster involving the partitioning of an organic pesticide in agricultural land near a river and propose a mitigation strategy.

   Hint

   Consider how plants can play a role in filtration.
