Three exposure levels of toluene were inhaled by dogs for 1 h. Toluene concentrations in expired air, arterial blood and venous blood were repeatedly measured. Absorptions of toluene within one hour of exposure were 25, 56 and 74 mg/kg at 700, 1500 and 2000 ppm respectively (absorption ratio = 27%). The cumulative excretion one hour after exposure was 63% of the absorped material at all three exposure levels. Multiple regression analyses were performed to interconnect the independent variables.
让狗吸入三种暴露水平的甲苯，持续1小时。对呼出气体、动脉血和静脉血中的甲苯浓度进行反复测量。在700、1500和2000 ppm浓度下，暴露1小时内甲苯的吸收量分别为25、56和74毫克/千克（吸收比率 = 27%）。在所有三种暴露水平下，暴露1小时后的累积排泄量为吸收物质的63%。进行多元回归分析以关联自变量。
