[Effect of working in a coke plant on levels of carbon monoxide hemoglobin in employed workers].Med Pr. 1993; 44(2):117-20.MP
Concentrations of carbon monoxide hemoglobin in blood of 48 furnace-room, and of 31 carbon derivatives department workers for many years exposed to carbon monoxide (divided into smokers and non-smokers) were assessed by spectrophotometry. CO levels were within the values provided in the corresponding standards for the occupational exposure, there was, however, the risk of periodically exceeding the MAC values. It has been found that HbCO levels in the workers of the furnace room and of the carbon derivatives department were much significantly higher than in the controls, both in the smoker and in the non-smoker group.
