Ethyl Benzene Metabolite Profile, Urine
Monitor exposure to ethyl benzene
Gas chromatography (GC)
• Environmental exposure: None detected
• Occupational exposure: BEI® (sampling time is the end of shift at the end of the work week): 700 mg/g creatinine1
BEI® are reference values intended as guidelines for evaluation of occupational exposure. BEI® represent biological levels of chemicals that correspond to workers with inhalation exposure equivalent to the threshold limit value (TLV®) of the chemicals. TLVs refer to the airborne concentrations of substances and represent conditions under which it is believed that nearly all workers may be repeatedly exposed, day after day, without adverse health effects.1
Sampling time is the end of the shift at the end of the work week for industrial exposure monitoring. Metabolites with timing “end of shift at the end of the work week” (meaning four or five consecutive working days with exposure) are eliminated with half-lives longer than five hours. Such metabolites accumulate in the body during the work week; therefore, their timing is critical in relation to previous exposures.
