INVESTIGATION OF MECHANISMS OF OXYGEN DELIVERY TO THE TISSUES IN INDIVIDUALS WITH CHRONIC LOW-GRADE CARBON MONOXIDE EXPOSURE
The study evaluated two parameters related to blood oxygen delivery in employees of the Triborough Bridge and Tunnel Authority chronically exposed to automobile exhaust: red blood cell methemoglobin levels, and red blood cell 2,3-diphosphoglyceric acid levels. A slight but statistically significant elevation in methmoglobin levels was noted. In addition, a trend towards increases in red cell 2,3-diposphoglyceric acid concentrations was discernible. Cigarette smoking appears to contribute to both of these findings. No evidence of an elevation in hematocrit levels was observed.
