| Summary: | two sections. The first section addresses the results from a study on the acute toxicity of the oil dispersant Corexit 9500, and on the acute toxicity of fresh and laboratory-weathered Alaska North Slope (ANS) crude oil to the Alaskan Tanner Crab (Chionoecetes bairdi), two standard test species, and Vibrio fischeri (Microtox 7 bioassay). The second section is an assessment of Alaskan marine species for use in future toxicity tests. This project was conducted in conjunction with other laboratories of the Chemical Response to Oil Spills: Ecological Effects Research Forum (CROSERF) and followed the protocols established by this group. The only modifications were for the Tanner crab tests and include the use of saltwater from Resurrection Bay, Alaska, and temperatures representative of cold-region conditions. Section 1 Toxicity assays of the oil dispersant, Corexit 9500, and fresh and laboratory-weathered Alaska North Slope (ANS) crude oils were conducted on four species. The assays were conducted using cold-region conditions for Alaskan Tanner crab larvae (Chionoecetes bairdi). Standard conditions were used to test three reference species, Mysidopsis bahia, Menidia beryllina, and Vibrio fischeri (Microtox 7 bioassay). The purpose of this study was to evaluate the acute toxic |
