Abstract: In this experiment I compared the toxicities of Exxon Corexit 7664, 9550, 9527, and 9580, SLIK-A-WAY, Nokomis 3-F4, and Nutri-Bio 1000, with and without 1 gram of crude oil, using the splash pool copepod Tigriopus californicus as a test organism. Investigating T. californicus as a test organism revealed that males are more sensitive than females to change, that the organisms' survival is inversely proportional to the amount of crude in their environment, and that they survive longer in filtered water than in the tide pool water when no outside air is available. These preliminary studies resulted in the final sample of 5 female T. californicus (3 with eggs), in 3ml tide pool water, in a 12hr light/dark cycle at 15 degrees C, with and without 1 gram crude oil to test the cleaning reagents.
