摘要
长期接触木尘可使鼻粘膜炎、慢性支气管炎检出率明显增高。木工的鼻粘膜炎检出率与车间内木尘浓度有关。将木尘浓度控制在5mg/m^3以下,鼻粘膜炎检出率接近对照组水平,但不易实现。如木尘浓度维持在10mg/m^3或10mg/m^3以上时,木工的鼻粘膜炎检出率明显增高,比对照组高19.84～21.0%,对肺功能损害也比较重。若将木尘浓度控制在5～10mg/m^3之间,鼻粘膜炎检出率比对照组高13.7～14.3%,对工人健康虽有一定的危害但不严重。结合我国经济条件和防尘技术的可行性,建议木尘最高容许浓度为8mg/m^3。
Exposure to wood dust for a long time obviously increases the occurrenceof rhinitis and chronic bronchitis among wood workers with a dust concentra-tion dependent manner.If dust concentration is maintained below5mg/m^3,the prevalence of rhinitis will be close to the control level,but thisstandard is difficult to realize at present.If concentration is in the range from5mg/m^3 to 10mg/m^3,the prevalence of rhinitis will be 13.7-14.3 percenthigher,and the workers will suffer slight but not severe damage to theirhealth.A MAC value of 8mg/m^3 for wood dust is recommended,consideringthe economical and technical possibility for dustproof measures in thiscountry.
