| Abstract |
Carboxyhaemoglobin (HbCO) levels in the expired air before and after a work shift were estimated over 5 days at an integrated steelworks in 100 blast furnace workers and a control group of 87 men without CO exposure. The method proved simple, accurate, and very suitable for this type of investigation. The findings of a 1962 study, showing that irrespective of smoking habits blast furnace workers had significant increases in HbCO levels in end-of-shift samples as against controls, were confirmed. It was deduced that similar exposure to small CO concentrations occurred over the intervening period. Smokers had HbCO levels of 5% or more before exposure. Difficulties arising from the NIOSH recommendations of a time-weighted average (8h) of 35ppm CO are considered in the light of the findings obtained. |
