Abstract: The toxicity of several preparations obtained from Kuwait Crude oil to Tigriopus californicus was investigated. Whole oil, sea water extracted whole oil, the seawater extract, and similar material obtained from oil weathered for 40 days were compared. The LD-50's may be ranked as follows: The most toxic preparation was the seawater extract, followed by Whole Kuwait oil, washed Kuwait oil, weathered oil, and washed weathered oil, in order of decreasing toxicity. Males were found to be twice as susceptible as as females to the whole oil preparation. Assays conducted in an attempted simulation of the tidepool environment revealed higher toxicities than wree obtained under more tradition methods of assay.
