2 cards from this section. Quick, good the night before a test.
What is the soil-air interface?
Think about where soil meets the air.
Why is core sampling important?
Recall the techniques we discussed earlier.
What is the primary technique for measuring contaminant concentrations in the soil?
Think about how we obtain soil samples.
Flux is defined as the rate at which a substance passes through what?
Remember what flux evaluates.
You are measuring flux at a soil-air interface. If measurements show a 10% increase in contaminant concentration with a corresponding 5% increase in area covered, calculate the new flux.
Use basic percentage increase formulas.
Design a long-term study to monitor flux changes during seasonal variations. What parameters do you need to consider?
Seasonal changes should influence your measurements; plan accordingly.
