Environmental impact of used motor oil
1Centro de Investigaciones Biológicas de Baja California, La Paz B.C.S., Mexico.
Abstract:
The information concerning the effects of used motor oil on the environment is reviewed. The production and fate of used motor oil are analyzed and the effects on soil and aquatic organisms are described. The combustion of waste crankcase oil, with particular reference to environmental impact, is discussed. The mutagenic and carcinogenic effects of used motor oil are described. Information on the biodegradation of lubricating motor oil is also reviewed. The available information shows that used motor oil is a very dangerous polluting product. As a consequence of its chemical composition, world-wide dispersion and effects on the environment, used motor oil must be considered a serious environmental problem.
