| Abstract |
Many previous studies of oil toxicity used high oil concentrations and watersoluble fractions (WSF). The aim of this study was to approximate field conditions, in which weathering and chemical dispersions remove the volatile fractions and change droplet size. The objective was to discover whether reducing monoaromatics and diaromatics reduced toxicity. The study measured the relative toxicity of fresh Prudhoe Bay crude (PBC) oil and two distillation fractions ('Stage I' and 'Stage II') and their chemical dispersions to adult and larval shrimp and fish. The hydrocarbon composition of the three oils, the WSF of the oils, and chemical dispersions were measured. Tissue content of armatics was measured at points of zero mortality and 50% mortality. Distribution of oil droplet sizes in chemical dispersions of fresh PBC and Stage II oils were compared. |
