氟骨症患病率与燃煤的关系

本文对八个生产组居民平均烧煤时间、烧煤数量及室内空气氟调查结果与16岁以上当地居民氟骨症患病率进行了相关与回归分析。结果表明,氟骨症患病率与室内空气氟,烧煤年限、时间及数量之间均有极显著相关关系。相关系数分剐为0.939、0.955、0.896及0.791(P<0.01)。此外,本文还对燃煤型氟中毒定量流行病学进行了初步探讨。结果说明,氟骨症患病率与室内空气氟、烧煤时间等存在着剂量——效应关系。

THE RELATION OF THE PREVALENCE RATE OF OSTEOFLUOROSIS TO THE BURNING COAL

A correlation and regression analysis of the average time and amount of burning coal and fluoride content of indoor air in the eight groups and the prevalence rate of osteofluorosis of local inhabitants above the age of 16 were carried out in this Paper. The results showed that there was a clear-cut correlation between the prevalence rate of osteofluorosis and fluoride content of indoor air, number of years, time and amount of burning coal. The correlation coefficient was 0.939, 0.955, 0.896 and 0.791. respectively(P<0.01). In addition, this paper conducted a preliminary study on the quantitative epidemiology of coal-pollution-borne endemic fluorosis. The findings showed that there was a dose-response relationship between the prevalence rate of osteofluorosis and fluoride content of indoor air, time of burning coal and so on.
