摘要
本文对地氟病区唐家村和对照区双车村居民总摄氟量进行了调查、评价。成人每日摄氟量,唐家为5.12mg/人/日,双车为2.46mg/人/日。两地均超过 WHO 的推荐值。氟主要来自空气和食物,唐家显著高于双车。当地居民主要燃煤。两地所用煤的含氟量中等且无显著差异,但居民燃煤时要加30%～70%山土,而山土中的氟含量远远超过一般水平(200ppm),唐家为1414.3ppm,双车为539.4ppm。造成空气中氟含量过高。土壤氟为主要氟源。
Total fluoride intake in endemic fluorosis areas,Tangjia and Shungche of theLianyuan county,Hunan province were assessed.The fluoride was determined in air,food and tea,using a fluoride electrode.Air samples were collected on 0.1N sodium hydroxide (NaOH).Food sampleswere ashed and dissolved in hydrochloric acid (HCl).The daily fluoride intake of adults was 5.12 and 2.46 mg in Tangjia and Sh-ungche respectively.All exceeded the WHO recommened value which was mainlyevaluated from air and food,but not from tea.It was significantly higher in Ta-ngjia than in Shungche.In Lianyuan county,30%-70% soil was added to the coal for fires.The fluor-ide conents of coal in both areas were similar to the general value of Chinese coal,but the fluoride content of the soil exceeded the general value (200PPm).Tangjiawas 1414.3 ppm and Shungche was 539.4ppm.Therefore,the soil fluoride consti- tutes the major source.The prevalence and severity of mottled teeth,urinary and blood fluoride con-tents were higher in Tangjia than in Shungche.It was evident that fluoride intakeinfluences the correlations of health hazard.
