6. (10 points) Anthracene has contaminated harbor sediments and the solid portion of the sediments is in equilibrium with the pore water. If the organic carbon content of sediments is

5percent and the solid sediment anthracene concentration is 50 ug/kg sediment, what is the porewater concentration of anthracene at equilibrium? log Ko for anthracene is estimated to be4.32
