Challenge Problems
Push your limits with advanced challenges
Given fluctuating moisture levels in a region, model how the flux of a pesticide would change over a complete dry-wet cycle, and calculate expected flux values for each stage.
💡 Hint: Consider using equations we covered for relating moisture to flux.
If you have two soil specimens, one dry and one wet, use given data on partition constants and concentrations to calculate the expected flux rates from each soil type. Discuss the implications of your findings.
💡 Hint: Focus on the relationship between moisture levels and partition constants.
