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。
In this paper, the average production time of coal burning in eight production groups, the number of coal and indoor air fluoride survey results and residents over the age of 16 fluorosis prevalence and regression analysis. The results show that the prevalence of skeletal fluorosis and indoor air fluoride, coal age, time and quantity are extremely significant correlation between. The correlation coefficients were 0.939, 0.955, 0.896 and 0.791 (P <0.01). In addition, this paper also conducted a preliminary study on quantitative epidemiology of coal-based fluorosis. The results show that there is a dose-effect relationship between the prevalence of skeletal fluorosis and indoor air fluoride, coal burning time.
