PHYSICAL AND CHEMICAL CHANGES IN SPILLED OIL WEATHERING UNDER NATURAL CONDITIONS
This report summarizes and discusses observations made during a study of the long term behavior of oil weathering under natural conditions. The specific case examined is that of a spill of Bunker C oil which occurred in Chedabucto Bay, Nova Scotia in February 1970. A sampling program organized for this study included analysis of viscosity, density, and concentration of nickel, vanadium, sulfur, and asphaltenes. The specific analytical techniques utilized in the sampling program are discussed. Results of these analyses indicated that changes in physical properties and chemical composition occurred fairly rapidly in the initial few months, but little change occurred subsequently. Based on these results, the authors conclude that the effect of a residual fuel spill, in similar circumstances, will be evident for many years. The authors advise that the results and conclusions based on this study should not be generalized to a great extent in attempting to predict the effects of other spills.
