Cumene is released to the environment as a result of its production and processing, from petroleum refining and the evaporation and combustion of petroleum products and by the use of a variety of products containing cumene. When released to the atmosphere, vapour phase cumene will react with photochemically generated hydroxyl radicals with an estimated half-life of 25 hours in polluted atmospheres and 49 hours in normal atmospheres. Cumene is a contaminant of air, sediments and surface, drinking and groundwater and a natural constituent of a variety of foods and vegetation.
