【摘要】：目的掌握广西外环境水碘分布状况,建立该地区水碘数据库。方法每个县区随机选择5个乡镇,每个乡镇随机选择4个行政村,每个行政村随机选择1个自然村作为监测点。分散式供水按"东西南北中"5个方位,各采集1份居民饮用水水样;集中式供水则选择2户,各采集1份末梢水水样。在全区109个县区的2 115个乡镇7 735个行政村14 187个自然村共采集26 704份水样,采用水碘检测试剂盒测定水碘浓度。结果水碘中位数为2.20μg/L,平均值为6.47μg/L。其中,水碘10μg/L的水样占86.28%,10~150μg/L的占13.59%,150μg/L的占0.13%。结论广西绝大部分区域属于缺碘地区,缺碘地区严重程度从西北向东南随地势倾斜稍有改善,未发现高碘地区。
[Abstract]:Objective to understand the distribution of water iodine in the external environment of Guangxi and to establish the water iodine database in this area. Methods five villages and towns were randomly selected in each county, 4 administrative villages in each township, and one natural village as a monitoring point in each administrative village. One sample of drinking water was collected in each of the five directions of "East, West, North, South and Middle", while two households were selected for centralized water supply, and one sample of peripheral water was collected for each of them. A total of 26 704 water samples were collected from 2 115 townships and 7 735 administrative villages in 109 counties in the whole region. The water iodine concentration was determined by water iodine detection kit. Results the median iodine in water was 2.20 渭 g / L and the average was 6.47 渭 g / L. Among them, water samples of 10 渭 g / L of iodine in water account for 86.28 渭 g / L and 10 渭 g / L for 13.59 渭 g / L, and 0.13 for 150 渭 g / L of iodine. Conclusion most of the regions in Guangxi belong to iodine deficiency areas, and the severity of iodine deficiency areas from northwest to southeast is slightly improved with topographic tilt, and no high iodine area is found.
