The relationship between external dose and internal dose of trichloroethylene (Tri) was analyzed by using a physiological simulation model. The external dose of Tri was represented by the time-weighted average (TWA) concentration in inhaled air or by the product of exposure concentration and exposure duration, and the internal dose by the area under the curve (AUC) of Tri blood concentration or...
