Priority Substances List Assessment Report: Waste Crankcase Oils. CanadianEnvironmental Protection Act

摘要

The priority substance 'waste crankcase oils' (WCOs) is defined as usedlubricating oils removed from the crankcase of internal combustion engines. For the purpose of this assessment, the life cycle of WCOs was considered to begin at the point of collection. During collection, WCOs are frequently mixed with other waste oils. Therefore, the definition of WCOs also includes these mixed waste oils. In this assessment, an attempt was made to follow the life cycle through to their ultimate disposal. Waste crackcase oils and their constituents may be released to air, water, and soil. There is insufficient information to estimate the exposure of humans to WCOs. Therefore, based on these considerations, it has been determined that there is insufficient informaiton to conclude whether waste crankcase oils are entering the environment in a quantity or concentration or under conditions that are having a harmful effect on the environment.
