Chemical analyses of four lots of No.2 fuel oils were carried out. They were Montana, Baytown, New Jersey and Baton Rouge, supplied by Exxon Corporation. The major components of aromatics in the water solubles were identified and concentrations determined. The fuel oils were tested against six strains of microalgae, two blue greens PR-6 (Agmenellum quadruplicatum) , 17A (Coccochloris elabens) , two greens DUN (Dunaliella tertiolecta) , 508 (Chlorella autotrophica) ; and two diatoms N-1 (Cylindrotheca sp) and AMP-1 (Amphora sp). Microalgae differed in sensitivity to an oil; an alga differed in sensitivity to the several oils. Data are presented for toxicities of aromatic compounds found in oils; toluidines were especially toxic to blue-green algae. Animals - barnacle eggs, nauplii, sand dollar eggs and embryos, crab larvae, a pteropod - were exposed to crude oils, fuel oil and aromatic compounds, and mortalities determined. Fuel oils and crank-case oils were especially toxic. Changes of behaviour were noted.
