目的 了解内蒙古饮茶型氟中毒病区居民砖茶中氟和茶多酚含量及氟含量合格砖茶的使用情况.方法 选取陈巴尔虎旗和鄂温克旗两个地区作为调查点.在陈巴尔虎旗选择4个村的72户居民,在鄂温克旗选择3个村的11户居民作为调查对象.采集每户的砖茶样品,测定氟和茶多酚含量.砖茶氟含量测定采用离子选择电极法,砖茶中茶多酚含量测定采用福林酚氧化分光光度计法.采用t检验、线性相关进行统计分析.结果 氟含量合格砖茶茶氟平均值为171.78 mg/kg,范围为114.82～290.23mg/kg;茶多酚含量平均值为95.44g/kg,范围为56.15～132.18g/kg;茶氟含量不合格砖茶茶氟平均值为459.86mg/kg,范围为304.71～660.76mg/kg;茶多酚含量平均值为67.48 g/kg,范围为36.03～102.15g/kg.合格砖茶茶多酚含量显著高于不合格砖茶(P＜0.05);砖茶氟含量与茶多酚含量具有负相关关系(r=-0.636,P＜0.05),砖茶中茶多酚平均是氟含量的396倍,病区居民合格砖茶使用率为53.0％ (44/83).结论 饮茶型氟中毒病区合格砖茶氟含量明显低于不合格砖茶,茶多酚明显高于不合格砖茶,合格砖茶使用率不高,应进一步加强防治措施落实进度.
目的 瞭解內矇古飲茶型氟中毒病區居民磚茶中氟和茶多酚含量及氟含量閤格磚茶的使用情況.方法 選取陳巴爾虎旂和鄂溫剋旂兩箇地區作為調查點.在陳巴爾虎旂選擇4箇村的72戶居民,在鄂溫剋旂選擇3箇村的11戶居民作為調查對象.採集每戶的磚茶樣品,測定氟和茶多酚含量.磚茶氟含量測定採用離子選擇電極法,磚茶中茶多酚含量測定採用福林酚氧化分光光度計法.採用t檢驗、線性相關進行統計分析.結果 氟含量閤格磚茶茶氟平均值為171.78 mg/kg,範圍為114.82～290.23mg/kg;茶多酚含量平均值為95.44g/kg,範圍為56.15～132.18g/kg;茶氟含量不閤格磚茶茶氟平均值為459.86mg/kg,範圍為304.71～660.76mg/kg;茶多酚含量平均值為67.48 g/kg,範圍為36.03～102.15g/kg.閤格磚茶茶多酚含量顯著高于不閤格磚茶(P＜0.05);磚茶氟含量與茶多酚含量具有負相關關繫(r=-0.636,P＜0.05),磚茶中茶多酚平均是氟含量的396倍,病區居民閤格磚茶使用率為53.0％ (44/83).結論 飲茶型氟中毒病區閤格磚茶氟含量明顯低于不閤格磚茶,茶多酚明顯高于不閤格磚茶,閤格磚茶使用率不高,應進一步加彊防治措施落實進度.

Objective To determine the contents of fluoride and tea polyphenols in brick-tea and to understand the utilization ratio of qualified brick-tea in fluorosis regions in Inner Mongolia.Methods The investigation was carried out in Chenbaerhuqi Country and Eweukeqi Country.Seventy-two households of four villages in Chenbaerhuqi and 11 households of three villages in Ewenkeqi were selected as study subjects.The brick-tea in each household was sampled.The contents of fluoride and tea polyphenols were determined by using fluoride selective electrode method and Forint-Ciocalteu oxidation method,respectively.T test and linear correlation were used to analyze the data.Results The fluoride content in qualified brick tea ranged from 114.82 mg/kg to 290.23 mg/kg with an average value of 171.78 mg/kg,while tea polyphenols content was between 56.15 g/kg and 132.18 g/kg with an average value of 95.44 g/kg.In unqualified brick-tea,the average fluoride content was 459.86 mg/kg with the range from 304.71 mg/kg to 660.76 mg/kg and the average of tea polyphenols was 67.48 g/kg with the range from 36.03 g/kg to 102.15 g/kg.The content of tea polyphenols of qualified brick tea was significantly higher than that of unqualified brick tea (P ＜ 0.05).The content of tea polyphenols was negatively correlated with fluoride content(r =-0.636,P ＜ 0.05).The content of tea polyphenols was 396 times more than that of fluoride in brick tea.The utilization ratio of qualified brick-tea in the investigation areas was 53.0％(44/83).Conclusion The fluoride content in qualified brick-tea was less than unqualified brick-tea,and the tea polyphenols of qualified brick-tea was higher than the unqualified brick-tea.The utilization rate of qualified brick tea is not high and further actions are needed to be taken to supply more qualified brick-tea for controlling of drinking brick-tea type fluorosis.
