Atrazine is adsorbed to a soil that is only saturated by 5%(i.e. only a twentieth of the pore volume is filled with water), how much atrazine is bound to the soil, dissolved in the water, and present as vapor in the gas phase? The amount of atrazine applied to the soil is 1.25 lb/acre. Assume the atrazine resides in the top 12 inches of the soil. Log Kow for atrazine is 2.65. Kd is 7.73 cm^3/g. Bulk density is 1.25 g/cm^3. The soil porosity is 0.4.
