Abstract:
OBJECTIVETo study the influence of occupational exposure and smoking on lung ventilation function of coke oven workers.
METHODSEnvironmental monitoring was performed on the top, side and bottom of some coke ovens. Lung ventilation function test was performed in 234 coke oven workers.
RESULTSThe poison concentration in environment had such tendency as it was the highest on the top, then the side, and the lowest at the bottom. The standardized forced expiratory volume in the 1st second (FEV(1), 90.8% +/- 8.6%) and forced expiratory rate (FEV(1)%, 95.4% +/- 12.4%) of those coke oven workers who smoked were significantly lower than those non-smoking workers (100.9% +/- 14.3%, 108.9% +/- 17.6%); among those smoking workers, the partial correlation coefficients between forced vital capacity (FVC) and benzene soluble, benzopyrene, and smoking index were -0.249, -0.187 and -0.368 respectively; and the coefficients between FEV(1) and the three aspects were -0.255, -0.191 and -0.388; and the coefficients between FEV(1)% and them were -0.131, -0.107 and -0.065. Among those non-smoking workers, the coefficients between benzene solubles and FVC, FEV(1) and FEV(1)% were -0.154, -0.052 and -0.176, and between benzopyrene and them were -0.121, -0.037 and -0.159.
CONCLUSIONThe lung ventilation function of coke oven workers has certain negative correlation with both occupational exposure and smoking.
