评价生产场所化学物的接触水平,传统的方法是测定空气中化学物质浓度。但在某些情况下,特别当化学物质可以通过皮肤吸收时,会造成错误的评估结果。由于空气中化合物的浓度在不同时间和不同的作业点并不相同,加上接触者的工作习惯不同,即使在同样的空气浓度下,从空气中吸收化学物质的量也有着明显的个体差异。因此,在上述情况下与环境监测相比,生物监测能较好地表示化学物的吸收量。已开展的生物监测项目和动态芬兰赫尔辛基职业卫生研究所生化实验室和地区实验室,开展近40种生物监测指标的分析研究工作。详见表1。经典的生物监测是测定接触工人血、尿中化学物 The level of exposure to chemicals in production sites is assessed by the traditional method of determining the concentration of chemicals in the air. But in some cases, especially when chemicals can be absorbed through the skin, it can cause false assessment results. Because the concentrations of airborne compounds are not the same at different times and at different points of operation, plus the different working habits of the contacts, there is also a distinct individual difference in the amount of chemicals absorbed from the air even at the same air concentration. Therefore, compared with environmental monitoring, biological monitoring can better represent the absorption of chemicals in the above situations. The biological monitoring project and the dynamic biochemistry laboratory and the regional laboratory of Helsinki Institute of Occupational Health in Finland carried out analysis and research work on nearly 40 biological monitoring indicators. See Table 1 for details. Classic biological monitoring is the determination of exposure to workers blood, urine chemicals
