1. Environmental Quality Monitoring Analysis

Try these first

1. 1.

   What does Rho A1 represent?

   Hint

   Think about the first phase discussed.

2. 2.

   What does the star in Rho A2* signify?

   Hint

   What does equilibrium mean in terms of concentration?

3. 3.

   What does Rho A1 indicate?

   • Concentration in soil
   • Concentration in air
   • Concentration in water

   Hint

   Refer back to the definitions of Rho.

4. 4.

   True or False: Henry's constant relates to the partitioning of a substance.

   • True
   • False

   Hint

   Consider what Henry's constant defines.

5. 5.

   Given concentrations of a pollutant in air and water, calculate the Henry’s constant. If Rho A1 is 5 mg/m3 and Rho A2 is 0.2 mg/L, find Henry’s constant.

   Hint

   Convert units if necessary to match or use consistent measurements.

6. 6.

   Assuming soil A has 30% organic material and soil B has 10%, discuss the expected partitioning of an organic chemical between these soils.

   Hint

   Reflect on the interactions of organic chemicals with organic matter.
