Abstract

As the biological effects of the volatile aromatic compounds in crude oil are not well documented a systematic examination of these compounds was initiated at the National Marine Fisheries Service at Tiburon. One of the major constituents of these aromatic compounds is benzene. The acute toxicity of benzene to 1.5 ± 0.5-g juvenile striped bass (Morone saxatilis) was studied in a continuous flow laboratory bioassay system. At 17.4 C and 29 ppt salinity, the lethal threshold concentration and the 96-h LC50 for benzene were 10.9 μl/liter. The 95% confidence interval was 10.9 ± 0.2 μl/liter and the probit line slope, "S," was 1.1.Possible toxic mechanisms are discussed.
