研究不同含矽量的粉尘浓度和其它因素与矽肺发病关系,可为车间粉尘浓度的卫生标准提供理论根据,对预防矽肺的发生,保证工人健康有重要意义。 我们用逐步回归和寿命表两种方法、研究了含矽量低但浓度较高粉尘与矽肺发病的关系,现又以同样方法研究低浓度含矽量高粉尘与矽肺发病的关系。本资料曾用中国医学科学院和辽宁省劳卫所的方法分别计算过,结合本研究,亦可从方法学相互比较。 研究对象 无锡干磨石英厂接尘者200人,矽肺患者20人,其中16例在调离粉尘环境后发生矽肺。厂内基本情况详见另文。
Studying the relationship between dust concentration and other factors and the incidence of silicosis in different amounts of silicon-containing dust can provide a theoretical basis for the hygiene standards of dust concentration in the workshop and is of great significance in preventing the occurrence of silicosis and ensuring the health of workers. We used stepwise regression and life table two methods to study the relationship between low silicon content but high concentrations of dust and silicosis, and now the same method to study the relationship between the low concentration of high silicon content of dust and silicosis. This information has been calculated using the methods of the Chinese Academy of Medical Sciences and Liaoning Provincial Health Institute, combined with this study, but also from the methodology of mutual comparison. Subjects Wuxi dry grinding quartz plant dust-200 people, silicosis patients 20 people, of which 16 cases in the transfer of dust from the environment after the occurrence of silicosis. The basic situation of the factory see the other.
