Toluene in Blood after Exposure to Toluene

AIHAJ, 1988
Analysis of the postshift toluene levels in the blood of 50 assembly line workers indicates that toluene levels in blood were correlated with the time-weighted average (TWA) exposure levels of the same day (r = 0.90). Toluene concentrations in 10 laboratory technicians not exposed to toluene at their work gave an average level of 0.002 microgram/mL of ...
