摘要
目的对燃煤型氟中毒改灶后５年居民室内的主要携氟介质的氟含量进行综合评价，以此论证监测方案的可行性。方法按全国统一监测方法，每年同一时间对我省５个重点监测点进行调查，包括采样分析。结果室内空气氟的一次性检测结果与同期检测的室内食物氟含量的结果不相吻合。虽然空气氟含量有所降低（０．００１３～０．０１４２ｍｇ／ｍ３），但室内玉米，辣椒氟含量在不同年份间仍有回升，８～１２岁学生尿氟含量亦保持在较低水平，氟中毒病情监测呈下降趋势。结论在对燃煤污染型氟中毒病区的改灶后监测时，除观察儿童氟斑牙率和尿氟含量外。
Objective To demonstrate the feasibility of the surveillance programme.Comprehensive evaluation of F concentration of indoor media was carried out based on the 5 year surveilance on Fluorosis caused by coal smoke after stoves had been improved in severe areas of Guizhou prvince.Methods According to the national unified measurement of surveillance,investigation were carried ory in 5 severe disase areas of Guizhou province the same time every year,specimens were collected and analysed.Results The F concentration of indoor air was not accord with that of indoor foods during the same time.Although F concentration of indoor air diminished gradually (0.0013￣0.0142mg/m 3),but the F concentration of indoor foods,like chilli and corn,tend to be increased in different years.Urinary F of specimans collected from students (age from 8 to 12) remained a lower level.It showed a decrease tendency of Floursis.Conclusions When investigating the Flourisis caused by coal smoke in the areas where stoves had been improved,we should focus not only on Urinary F and dental Fluorisis of children but also on F Concentration of indoor foods.
