Water and air samples collected from treated and untreated simulated oil spills have been analyzed for hydrocarbons. In test tanks, 6.2 m tall, the concentration of oil in the water just beneath the surface is initially 27 times greater when a dispersant is used. During a 3-day experiment, however, the amount of oil in the water column decreased significantly in both the treated and untreated cases. When a dispersant was used, the maximum concentration in the water column gradually moved toward the bottom of the tank. Results of laboratory, meso scale, and a real spill are compared. |
