The carboxyhaemoglobin (COHb) levels of two groups of workers in the City of London were determined. The mean COHb in smokers (5-8%) was significantly greater than that of the non-smoking group (1-3%). In general, cigarette consumption could be directly related to the COHb level but there was considerable individual variation. The mean COHb level of manual workers was significantly lower than that of sedentary workers even though the former group tended to smoke more heavily.
测定了伦敦市两组工人的碳氧血红蛋白（COHb）水平。吸烟者的平均碳氧血红蛋白水平（5 - 8%）显著高于非吸烟组（1 - 3%）。一般来说，香烟消费量与碳氧血红蛋白水平直接相关，但个体差异较大。体力劳动者的平均碳氧血红蛋白水平显著低于久坐不动的劳动者，尽管前一组吸烟量往往更大。
