| Summary: | decisions regarding chemical dispersants use in oil spill response in Alaska consider the potential impacts of chemically dispersed oil, including the toxicity to aquatic organisms. This review critically evaluates the aquatic organism toxicity testing protocols developed by the Chemical Response to Oil Spills: Ecological Research Forum (CROSERF) for applicability to assessing chemical dispersant toxicity under subarctic conditions. CROSERF was established as a working group of industry, government, and university scientists to coordinate and disseminate research on chemical oil spill dispersants. CROSERF participants developed aquatic toxicity testing protocols during 1994 to 2000 with the foremost objective of standardizing test methods and reducing inter-laboratory variability. A number of refinements are recommended to adapt the CROSERF protocols for testing with subarctic species under conditions of expected longer oil persistence. Recommendations were focused on providing toxicity test data most relevant to risk management decisions regarding dispersant use in subarctic environments, rather than the primary CROSERF objective of standardizing procedures. Recommended refinements of the CROSERF protocols include (1) testing both a fresh and moderately weathered oil under conditions of moderate mixing energy, (2) testing both Corexit 9500 and 9527 using a high |
