The compound methyl-tert butyl ether (MTBE) has been used extensively as a gasoline additive. If 100 kg of this compound were accidentally spilled into a lake over the course of a summer, calculate the concentrations in water, sediment, and fish (neglect volatilization) that would result. Assume that the volume of the lake is 8 * 10 7 m 3 , the organic solids loading is 20 ppm, and the fish loading is 2 kg per 10 4 m 3 . Assume that the lake is well mixed.
a. What are the concentrations in water, sediment, and fish?
b. What fraction of the MTBE would be found in the sediment?
c. What fraction would be found in the fish?
d. If you swallowed 1 L of water during a day while waterskiing, how much MTBE would you ingest?
Soil adsorption coefficient: 11.56 L/kg
Bioaccumulation factor: 3.162 L/kg wet-wt
