Ethylbenzene: Sources of emissions
Industry sources
Point sources of ethylbenzene are factories that use ethylbenzene as part of their manufacturing process and from coal tar and petroleum processing facilities. Ethylbenzene is also emitted from some hazardous waste sites.
Diffuse sources, and industry sources included in diffuse emissions data
Ethylbenzene is emitted from a wide range of products and has been widely detected in low concentrations both indoors and outside. Indoor concentrations may be higher due to a greater number of sources. It is present in tobacco smoke.
Natural sources
It occurs naturally in coal tar and petroleum.
Transport sources
Ethylbenzene will be released from fuel filling and from vapours from motor vehicle fuel tanks.
