对 2 2 0名柞蚕丝生产加工工人及 332名不接触尘毒的对照工人进行了呼吸系统症状的询问调查及肺功能检测。并对经常有呼吸系统症状者进行了胸部正位X线检查 ,对各加工工序进行了空气真菌学调查。结果表明 :柞蚕丝生产加工工人的呼吸系统症状阳性率和肺功能各项指标的异常率与相应的对照组相比显著增高。X线胸片有炎症片状影者 5人 ,经常发热的工人 15人 ,且均工作于前纺和后纺工序。各工序空气中的真菌个数较对照现场明显增高 ,波动范围达 190 2 6～ 2 110 9 8cfu/m3,并以前纺和后纺工序真菌个数最高。菌相分布以芽枝霉为主 ,其次为交链孢霉。提示柞蚕丝生产环境对工人呼吸系统的损害可能与芽枝霉、交链孢霉有关。
Inquiries on respiratory symptoms and pulmonary function tests were conducted on 220 nude silkworkers and 332 non-contact control workers. And often have respiratory symptoms were chest X-ray examination of the processing operations of the air mycological investigations. The results showed that the positive rate of respiratory symptoms and the abnormal rate of various indexes of pulmonary function in tussah silk production and processing workers were significantly higher than those in the corresponding control group. X-ray chest film inflammation of the shadow of 5 people, 15 workers often fever, and are working in the former spinning and after spinning process. The number of fungi in each process air was significantly higher than the control site, the range of fluctuation was 1902 6 ~2 110 9 8cfu / m3, and the number of fungi in the former spinning and post-spinning processes was the highest. Strains of the main distribution of budding mold, followed by Alternaria Alternaria. Tip Tussah silk production environment on the workers respiratory system damage may be associated with budding mold, Alternaria Alternaria.
