| 摘 要： | 用指数曲线、双曲线和抛物线拟合方法，研究了棉尘症患病率和纯棉总尘浓度的关系，发现指数曲线的议程式拟合最佳，据此推算车间棉尘浓度卫生标准，若把棉尘症患病率控制在6%，接触棉尘工人连续工作25-30年，棉尘的卫生标准订为1-2mg/m^3较为安全；若患病率控制在8%，则棉尘浓度标准应为3-4mg/m^3。

| Abstract: | The relationship between prevalence of byssinosis and dust concentration by the methods of exponential curve, hyperbola and parabola fitting was studied. After a lot of calulation and comparisons, the best equation which used to estimate the standard concentration of dust was the equation of exponential curve fitting. Supposing the prevalence is 8% and workers have served in the cotton mill for 30 years continuously, the better and greater safe standard at the level of 3-4 mg/m~3 was suggested. That is the most effective measure to protect the health of the cotton textile workers. |
