Assessment of the Phototoxicity of Weathered Alaska North Slope Crude Oil to Juvenile Pink Salmon

The objective of this study was determine if weathered ANS crude oil would be phototoxic to juvenile pink salmon under conditions of short-term exposures to high levels of oil that may occur during an oil spill, and environmentally relevant levels of UV in natural waters. The results of this study indicate that pink salmon are at less risk from photoenhanced toxicity compared to early-life stages of several other Alaska species. Phototoxicity could occur under conditions of higher UV exposure, but additional research is not currently recommended as a high priority.

Critical Evaluation of Chemical Response to Oil Spills: Ecological Research Forum (CROSERF) Test Methods for Oil Dispersant Toxicity Testing under Subarctic Conditions

The Alaska Region Oil and Hazardous Substance Pollution Contingency Plan requires that 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.
