Description and Uses
Professions that involve dealing with the combustion of coal or wood may be exposed to higher levels of cresols than the general population. Environmental tobacco smoke is also a source of cresol exposure. Average cresol concentration may vary between the brand and type of cigarette in a 45-cubic meter chamber after six cigarettes had been smoked (ranged from 0.17 to 3.9 mg m3), although low levels of cresol can be detected in certain foods and tap water, and these do not constitute major sources of exposure for most population. Detectable levels of cresols have been reported in several consumer products including tealeaves, tomatoes, and ketchup as well as butter, oil, and various cheeses. Exposure to children occurs by the same routes that affect adults. Children are likely to be exposed to cresols through inhalation of contaminated air from automobile exhaust, waste incineration, and secondhand smoke.
Cresol is used in disinfectants and fumigants,in the manufacture of synthetic resins, inphotographic developers and explosives.
