MORE INFORMATION ON AROMATIC HYDROCARBONS (PAH):
PAHs are formed during the incomplete combustion of organic material such as wood, coal or oil. Consequently PAH-containing extender oils are inexpensive and are used in many different consumer products. Industrial soot itself is often used to colour plastics and rubber black. Many PAHs have carcinogenic, mutagenic and/or plant-endangering properties. Some PAHs are simultaneously persistent, bio-accumulative and toxic to humans and other organisms.
Incomplete combustion occurs generally when the temperature of a fire is lower; if less oxygen is available, the more incompletely materials burn and the more PAHs are formed. However, a large proportion of PAHs reach the atmosphere through natural processes such as forest fires or volcanic eruptions that cannot be influenced by humans.
Human-induced PAH emissions also come from other combustion processes: i.e small incineration plants, industrial processes, fireplaces or tobacco smoke.
