Clinical Significance
Phenol is used in the manufacturing of plastics, fibers, adhesives, steel and rubber processing, and widely used as a disinfectant. It can also be found in throat lozenges, cigarette smoke, auto exhaust and hazardous waste sites. Benzene exposure is determined by the analysis of phenol, which is a metabolite of benzene. Symptoms of exposure may include irritation of the skin, cyanosis, paleness, general pallor, sweating, abdominal pain, vomiting and bloody diarrhea.
