A model sewer was constructed to determine the behaviour of fuels spilled into sewers and to test countermeasures for such spills. The model sewer inclIt was found that vapours in sewers have two distinct origins: the first is vapour formed upon fuel entry into the sewer and the second source is evapoThe use of dispersants on fuel spills in sewers increases both the maximum vapour concentrations observed and the total amount of vapour released. ThisThe use of heavy gases, carbon dioxide in various forms and Halon 1301, was also evaluated. Heavy gases reduce both the maximum concentration and totalThe study shows that the use of dispersants on fuel spills in sewers is not recommended as their use results in higher vapour concentrations. The use o

A brief overview is provided, based on several recent reports, of the dominant factors and processes which influence the behaviour and physical fate of spilled crude oil in the remote harsh Arctic offshore regions. These factors and processes include physical-chemical properties, evaporation, dispersion, dissolution, emulsification, physical movement and interaction with ice. Rates of the individual dominant processes for a typical Beaufort oil in the Beaufort Sea under different physical environments are approximated and applied to various spill scenarios. Research needs in this field are summarized.

... This suggests that the harmful effects of spills on marine ecosystems may persist over this period. In addition, the long-term oil film covering the Arctic ice will enhance the ice's heat absorption capacity and accelerate the ice's melting (Bobra and Fingas, 1986;Dickins, 2011), which will potentially impact the global sea level and long-term climate changes. ...
