Problem 4. It is known that 1kg of dry soil initially contains 250mg of dieldrin (a pesticide). The soil contaminated with dieldrin is then poured in to 1m3 of water and mixed mechanically till they are equilibrated. Assume that the organic content of soil (c) is 20%, dieldrin is nonvolatile, and temperature is 25C, calculate: a) Soil-water partition coefficient (KA32) as Lw/kg.(10p) b) Calculate equilibrium concentrations of dieldrin in soil as mg/kg and water as mg/L ( WA and A2 ). (15p) Note: some physicochemical properties of dieldrin are given by the following table
