Benzene, BloodALLng/mL

General U.S....
General U.S. population from CDC-NHANES (2017-2018) (n=2840) is typically less than 0.263 ng/mL (95% CI, 0.207-0.319 ng/mL) (95th percentile)
According to CDC-NHANES (2015-2016) blood benzene concentrations are generally less than 0.642 ng/mL (95th percentile) in smokers and less than 0.250 ng/mL in non-smokers

Following exposure to 25 ppm in air for 2 hours, the blood benzene concentration is approximately 200 ng/mL
