RT Journal Article SR Electronic T1 Carboxyhaemoglobin levels in workers in Leicestershire garages. JF British Journal of Industrial Medicine JO Br J Ind Med FD BMJ Publishing Group Ltd SP 238 OP 241 DO 10.1136/oem.36.3.238 VO 36 IS 3 A1 G R Kelman A1 T J Davies YR 1979 UL http://oem.bmj.com/content/36/3/238.abstract AB Blood carboxyhaemoglobin (HbCO%) levels were measured in 61 workers in 35 garages in Leicester and Leicestershire. Of 26 workers in large garages in winter, 44% of the non-smokers and 20% of the smokers had increased CO absorption, the highest HbCO% being 26.0 in a non-smoker. Of 35 workers in 24 smaller, randomly chosen garages visited throughout the year (two per month) the corresponding figures were 43% and 14%, the highest HbCO% being 21.0. The possible relevance of these findings to coronary heart disease in garage workers is discussed.
