人接触有机溶剂时,测定其肺泡中有害物质的浓度是常用生物监测方法。肺泡气中有害物质的浓度不仅反映接触水平,同时也间接地反映血液中有害物质的浓度。例如苯、甲苯、二甲苯和苯乙烯等吸入,测定吸入者的肺泡气,更具有毒理学意义。1 方法1.1 肺泡气采集用1只玻璃三通管,
Human exposure to organic solvents, the determination of the concentration of harmful substances in the alveolar is a common biological monitoring methods. The concentration of harmful substances in alveolar gas not only reflects the level of exposure, but also indirectly reflects the concentration of harmful substances in the blood. For example, benzene, toluene, xylene and styrene inhalation, inhaler measured alveolar gas, more toxicological significance. 1 Methods 1.1 Alveolar gas acquisition with a glass tee,
