Abstract
This paper outlines a dissolution model to show the fate of monocyclic aromatics, released from the diluent (thinning agent), in water during the simulated natural weathering of oil sands products (Access Western Blend, Western Canadian Select and Surmont Synthetic Bitumen) and conventional crude oil (Heidrun) on water. Based on mass balances ca. 0.3 to 4 % of the monocyclics were removed from the oil through dissolution, depending on oil type. Of the climatic factors assessed: air and water temperatures, wind speed and solar energy had a significant (p<0.05) effect on the rate of release and decay of monocyclics in water, depending on oil type. In addition, season had a significant (p<0.05) effect on the decay of monocyclics in water from spills of oil sands products, where a greater rate of decay occurred in summer than spring. This suggests that evaporation and possibly to a lesser degree photo-chemical weathering and biodegradation of these chemicals occurred in the water column.
