This paper embodies the preliminary results of experimental studies with different hydrocarbons such as crude oil, furnace oil, high speed diesel oil, benzene, hexane and xylene about their toxicity on phytoplaokters. The studies with these hydrocarbons on natural populations and selected . 1 species of .phytoplankton cultures showed that there is sometimes enhancement of photosynthesis with lesser concentrations of aqueous extract. The rate of production varies with different hydrocarbons depending on the species composition and it is found that the more toxic portions are the volatile fractions with low boiling point and the response is a function of species composition.
