1,3-Butadiene (vinyl ethylene): Sources of emissions
Industry sources
The primary stationary sources of 1,3-Butadiene are petroleum refining, manufacturing of synthetic materials and oil and gas extraction. These all emit to air.
Diffuse sources, and industry sources included in diffuse emissions data
Smoking tobacco, agricultural burning, bush or forest fires result in emissions to air.
Natural sources
1,3-Butadiene is emitted to air as a product of incomplete combustion in bush or forest fires, and the burning of biomass (wood, leaves, agricultural burning), including tobacco leaves.
Transport sources
Motor vehicles emit 1,3-Butadiene to air.
Consumer products
In almost all consumer products produced using 1,3-Butadiene, it has been reacted and is no longer available as 1,3-Butadiene. However, the burning of many consumer products will release 1,3-Butadiene. The burning of petrol (driving), leaves, or tobacco will release 1,3-Butadiene to air.
