Abstract
Several hundred products are currently available for the purpose of emulsifying or dispersing oil slicks. The products are marketed and sold throughout the country to individuals who have little or no knowledge of their relative effectiveness and toxicity. A brief history of the development of the Standard EPA Dispersant Effectiveness and Toxicity tests is outlined. The standard tests are presented and discussed. An analysis of variance is performed on the data developed by three independent laboratories in order to determine the reproducibility of standard test procedures. Separate discussion sections include the statistical analysis of 'testing the test' results for reproducibility and the rationale for selecting the test procedures as presented. (Modified author abstract)

Contents Notes
A brief history of the development of the Standard EPA Dispersant Effectiveness and Toxicity tests is outlined. The standard tests are presented and discussed. An analysis of variance is performed on the data developed by three independent laboratories in order to determine the reproducibility of standard test procedures. In the standard effectiveness test, oil is applied to the water surface in a cylindrical tank. Dispersant is applied in a fine stream and then mixing energy is supplied by a pressurized water stream. The tank contents are recirculated after which samples are withdrawn for extraction and spectrophotometric analysis. The standard toxicity test involves exposing three species (Pimephales promelas, Fundulus heteroclitus, and Artemia salina) to dispersant and oil/dispersant mixtures. From these tests a curve relating organism survival to material concentrations is developed to determine median tolerance limits. Separate discussion sections include the statistical analyses of "testing the test" results for reproducibility and the rationale for selecting the test procedures as presented.
