摘要
对８３例长期接触低浓度一氧化碳（ＣＯ）作业工人进行了血中碳氧血红蛋白（ＣＯＨｂ）含量的测定，血气分析及健康状况调查，并与６８名无毒害作业工人为对照做了对比分析。结果表明：①ＣＯ作业工人血中ＣＯＨｂ含量显著高于对照组，且就使血中ＣＯＨｂ升高而言，职业性接触ＣＯ显著高于吸烟，因此，ＣＯＨｂ是一个很好的接触指标；②ＣＯ作业工人末梢动脉血氧分压降低，并伴有神经衰弱和消化道障碍等症状。
workers exposed to low level CO as the exposed group and 68 unexposed to any harmful factors as the normal control, were investigated on the level of carboxyhemoglobin (COHb),the blood gas analysis and the workers′ health. Results showed:(1)The level of COHb in the exposed group was significantly higher than that in the control.In comparison with smoking, the effect of occupational CO exposure on the level of COHb is more serious. Thus, COHb could act as an ideal exposing index.(2) Partial pressure of O 2 in peripheral artery in exposed group was lower significantly than that in the control.Incidence of symptoms of neurasthenia and digestive functional disturbance was higher in workers exposed to CO.
