事故性氯气接触后对气道的影响一项对英国某纸浆厂316名工人的调查发现,有189人有一次或多次因泄漏而吸入氯气的既往史。他们中有气喘伴有呼吸短促的发生率显者高于不吸入氯气的对照组。经对吸烟修正以后仍见气喘症状增加。肺功能检查所见FEV_1、FVC、MMF和FEV_1/FVC的平均值两组之间无明显差异,但有氯气吸入史工人(不吸烟)的MMF和FEV_1/FVC之比均显著低于无吸入史者。研究人员认为,此与氯气泄漏事故的发生有关;工人中的气阳塞和呼吸系统症状的增加,在不吸烟者中尤为明显。
Impact on airways after accidental chlorine exposure A survey of 316 workers in a pulp mill in the United Kingdom found that 189 had one or more previous episodes of chlorine gas as a result of a leak. Among them, the incidence of asthma with shortness of breath was significantly higher than that of the control group without chlorine inhalation. After the amendment of smoking still see the symptoms of asthma increased. There was no significant difference between the two groups in mean values of FEV 1, FVC, MMF and FEV 1 / FVC found in pulmonary function tests, but the ratio of MMF and FEV 1 / FVC with chlorine inhalation to history workers (nonsmokers) was significantly lower than that without inhalation history By. Researchers believe this is linked to the occurrence of chlorine leaks; the increase in the presence of pneumoconiosis and respiratory symptoms among workers is especially pronounced among non-smokers.
