【摘要】 调查了5间木材加工厂453名木工。木尘浓度较高。木工中咽喉炎、鼻炎、慢支、结膜炎、哮喘、尘肺及过敏性皮炎的检出率分别为46.80%、34.22%、5.96%、4.42%、2.43%、1.55%和1.99%。前四种疾病发生率明显高于对照组(P<0.05)。木工肺通气功能有气道损害。提示木尘对工人的职业性危害是多方面的。更多还原

【Abstract】 Four hundred and fifty-three workers exposed to pure wood dust from 5 plants processed wood were investigated with a group of 128 nonexposed workers as a control. The wood dust concentration in the workshop air ranged between 0.8～180mg/m~3. The amount of particles less than 5 μm diameter were 52.9-68.7%. The content of the free silica was below 3%. The prevalent rates of chronic pharyngo-laryngitis, chronic rhinitis, chronic bronchitis, conjunctivitis, occupational asthma, pneumoconiosis and allergic dermatitis among 453 exposed workers were 46.80%, 34.22%, 5.96%, 4.42%, 2.43%, 1.55% and 1.99% respectively. The former 4 were statistically obviously higher among exposed groups than in control group (P<0.05). Pulmonary ventilatory function in exposed workers was characterized by airways, obstruction. These results suggest that a variety of occupation diseases may be elicited by the effect of wood dust. The etiology of wood pneumoconiosis and its clinical and X-ray menifesttions were discussed.更多还原
