摘要
目的调查贵州省燃煤污染型氟中毒重点病区主要携氟介质玉米和辣椒氟含量及变化，评估防控效果，为调整防控策略措施提供依据。方法2013年，存贵州省23个燃煤污染型氟中毒重点病区县（市、区），按照东、西、南、北、中5个方位各抽取1个乡镇，每个乡镇抽取3个病区村，每个村采集10户家庭食用玉米或干辣椒进行氟含量检测。将14个县的检测结果与2007年调查数据进行纵向比较。结果共检测玉米样品884份、辣椒样品3379份，玉米氟含量中位数为1．26mg／kg，范围为0．50～254．59mg／kg；辣椒氟含量中位数为9．15mg／kg，范围为0．50～3701．88mg／kg；14个县的检测结果与2007年调查数据比较，玉米氟含量中位数（mg／kg：1．36比2．63）降低了近50％，辣椒氟含量中位数（mg／kg：辣椒9．70比55．31）降低了80％以上，差异有统计学意义（Z=3.28、9．13，P均〈0．05）。结论贵州省燃煤型氟中毒重点病区县（市、区）玉米和辣椒携氟量显著降低，但局部病区玉米和辣椒携氟含量仍然较高。
Objective To investigate the content and changes of fluoride in corn and pepper, to evaluate the effect of prevention and control measures, and to provide a basis for adjusting the prevention and control strategy. Methods In 2013, according to the different directions of east, west, south, north and center, 5 townships were selected from each coal-burning-borne endemic fluorosis areas in all 23 counties （cities, districts）, and 3 villages was randomly selected from each township. Household samples of corn and dried pepper in 10 households were collected to detect fluorine content. The results of 14 counties were compared with the 2007 survey data. Results A total of 884 and 3 379 samples of corn and pepper were collected, and the median fluorine content was 1.26 and 9.15 mg/kg, the range was 0.50 - 254.59 mg/kg and 0.50 - 3 701.88 mg/kg, respectively. Compared with the survey data of 2007, the median fluoride content of corn of 14 counties decreased by nearly 50%, and the median amount of pepper was reduced by more than 80%. The differences were statistically significant （mg/kg： corn 1.36 vs 2.63, dried pepper 9.70 vs 55.31, Z = 3.28, 9.13, P 〈 0.05）. Conclusion The fluoride content of corn and pepper in Guizhou Province is significantly lower, but it is still relatively high in some coal-burning-borne fluorosis counties （cities, districts）.
