The renal elimination of verbenols after experimental exposure to (+) and (-)alpha-pinene was studied in humans following exposure to 10, 225, and 450 mg.m-3 terpene in an exposure chamber. The pulmonary uptake was about 60%. About 8% was eliminated unchanged in exhaled air. Depending on the exposure level, about 1%-4% of the total uptake was eliminated as cis- and trans-verbenol. Most of the verbenols were eliminated within 20 h after a 2-h exposure. The renal excretion of unchanged alpha-pinene was less than 0.001%.
