Question 1
Given that a certain area of soil has a partition constant of 0.5 in dry conditions and 0.2 in wet conditions, calculate the expected difference in pollutant flux assuming other factors remain constant.
💡 Hint: Consider how lower partition constants relate to higher mobility.
Question 2
You have a river with an inflow concentration of 50 mg/L and outflow concentration of 30 mg/L. If the flow rate is 100 L/min, calculate the flux.
💡 Hint: Make sure to account for the direction of flow and concentrations.
