| Abstract: |
| 对秀山、保靖燃煤氟中毒流行地区的环境氟和食品氟进行了调查。在对水氟、土壤氟、煤氟、气氟、尘氟、玉米氟、辣椒氟和其他蔬菜氟测定的基础上,首次阐明氟从煤进入人体导致当地氟中毒流行的迁移、转运途径是氟从煤-烟尘-玉米-人,该病流行的原因是煤烟尘污染玉米后经口摄入所致。证明了煤烟尘含氟量与玉米含氟量显著相关,并建议选用尘氟或空气氟作为室内环境质量和评价改灶降氟、预防氟病流行的监控指标。 |

This paper reports an investigation of contents of soluble flouride in the environment and foods in Xiushan and Baojing.
On the basis of measuring concentrations of soluble flouride in drinking water, soil, coal, air, fly ash, maize, chilli, and other kinds of vegetables, it is first to expound the pathway of fluoride migrating from coal into human body is through pollution of air by fluoride contained in fly ash on burning of coal, and then via consumption of polluted maize by air.
The significant correlation between both the concentrations of fluoride in maize and in fly ash is proved. It is suggested to select the concentration of fluoride in fly ash or in air as the quality index of indoor air and the control target to prevent fluorosis. |
