摘要

In March 1983, a fuel truck overturned at a bridge crossing the Cameron River, near Yellowknife, Northwest Territories, Canada, and spilled a quantity of diesel fuel. The spilled diesel fuel penetrated the snow cover, moved along the frozen surface of the ground and entered the ice-covered Cameron River. A sample of diesel fuel was recovered from beneath the river ice eight days after the initial spill. This sample from the river was compared with that from the original cargo in the truck in three quantitative and independent ways, namely gas chromatography with a comparison of the sample patterns by principal component analysis, acute toxicity to fish, and tendency to taint fish with an oily taste. The two samples were essentially the same in all respects, except for some subtle but consistent differences in the relative proportions of some individual hydrocarbons. The river samples were shown to contain slightly higher proportions of the C_8 to C_9 alkane components. Slightly lower proportions of alkanes eluted after C_(12), possibly as a result of losses due to sediment adsorption or fractionation under the ice. Evidently the low ambient temperatures and cover by ice and snow reduced greatly the 'weathering' phenomenon often described with spilled oils, and permitted the oil to retain its toxic and tainting properties.
