传统的工业卫生监测工作主要针对空气而言,因为经呼吸道侵入人体是最主要的途径之一。但空气监测并不能反映导致人体产生不良反应的各个方面。对于象铅、一氧化碳等这样的物质则可分析它们在生物材料(如血)中的浓度来监测其接触情况。近二十年来,人们开始更加系统地研究 Traditional industrial hygiene monitoring is mainly directed at the air, because invade the human body through the respiratory tract is one of the most important ways. However, air monitoring does not reflect all aspects of adverse human reactions. For substances such as lead and carbon monoxide, their concentrations can be analyzed in biological materials such as blood to monitor their exposure. For nearly two decades, people began to study more systematically
