AbstractA spiked-exposure toxicity test procedure has been developed, in which initial dispersant concentrations are diluted at a standardized rate to provide a simple model of exposure experienced in the field. Traditionally, acute dispersant toxicity has been described using constant-concentration exposures of 24 to 96 hours. Constant concentrations are unrealistic in the field because of the dilution effects of wind and wave conditions required for dispersant application. The spiked-exposure procedure has been adopted in California as a standardized tool for comparing dispersant toxicity. Five dispersants have been tested using four Californian species. Tests using oil and dispersant-oil mixtures are being developed.
