Assignment:
Consider a lake containing 39 ppb (parts per billion) of parathion, which has a log Kow = 3.8.
a. If a sample of lake water was mixed with octanol, what is the expected concentration of parathion in the octanol?
b. Assuming the body weight of a fish is 4% fat, what is the equilibrium concentration of parathion in the fish swimming in this lake?
Provide complete and step by step solution for the question and show calculations and use formulas.
