1. If the air above a settling pond has an equilibrium concentration of dichloromethane of 0.1 mg/m 3 , what is the concentration in the water phase in mg/L? (P v = 58 kPa and C wsat = 13 g/L at 25 C, MW = 85 g/mol) 2. Garth is an avid fisherman who catches and eats bass from a lake contaminated with 0.03 g DDT per liter of water. Assuming the fish have a lipid content of 4.8% and Garth eats 0.2 kg of fish per week, what is his average daily intake rate of DDT in mg/day? (Log K ow = 6.91, MW = 354.5 g/mol, fish density = 1000 kg/m3 ) Assume the bass Garth consumes are trophic level 4 consumers.
