Description:
Crude oil and/or refined oil products accidentally released in to coastal or oceanic waters will result in the formation of surface slicks that create dispersants under appropriate conditions. owever, prior to the use of dispersants at spill sites, information regarding the performance of available dispersant agents must be known (e.g., the relative performance of agents for dispersing oil in marine situations). hrough standardized laboratory testing procedures, the relative performance of dispersant agents can be evaluated. xperiments were conducted with four test methods to evaluate performance of dispersant agents under the direction of EPA's Risk Reduction Engineering Laboratory. ests were performed with five types of oil and three commercially available dispersants. tatistical analyses of the effects on test results of experimental variables (test method, oil type, dispersant type, and analytical wavelength in UV-visible spectrophotometric measurements) are presented and discussed.
