Abstract |
The blood circulation of 69 workers exposed to CO and 11 unexposed controls in a formic acid and oxalic acid works was examined by cerebral rheography. In the exposed group, 28 subjects had a history of acute CO poisoning due to plant leakages, although the CO concentration at the workplace was generally less than 30mg/m3. Consequently, average carboxyhaemoglobin concentrations were below 6%, but reached 18% in a few cases. Intracranial perfusion index anomalies were found in 74% of the subjects in this group. In a second group of exposed workers without any history of acute CO poisoning, pronounced haemodynamic anomalies were found in 39% of the cases. The authors conclude that the observed intracranial-circulation anomalies are due to "micro-poisoning" without loss of consciousness, rather than to the usual CO concentration at the workplace. |
