Title Evaluation of carbon monoxide exposure in an integrated coal chemical industry
Bibliographic information 1999, Vol.5, No.1, p.50-53. 10 ref.
Abstract An evaluation study of carbon monoxide (CO) exposure of workers in an integrated coal chemical industry was carried out. The highest mean environmental CO level was found to be 425ppm at the producer gas plant, whereas the mean minimum level was measured at 14.3ppm at pocking zones. In lock-hopper zones, the highest mean CO concentration was 338.7ppm during charging time. In the retort house, the mean CO level was 285ppm during charging time. The mean carboxyhaemoglobin (COHb) level of producer gas plant employees was 5.84, whereas the level was found to be 4.93 in employees working in the retort house. These values were significantly altered in comparison to controls (mean level of 1.66). Results indicate significant exposure to CO in both the producer gas plant and the retort house, which caused different clinical manifestations in the employees.
