微量元素-碘含量与饮水井深度关系的探讨

目的 :研究微量元素 -碘含量与饮水井深度之间的关系 ,寻找适碘饮水层。方法 :以居民饮用水碘含量为线索 ,对 42 3份水碘与其饮水井深度进行了相关分析。结果 :总体情况分析 ,水碘含量与饮水井深度之间呈正相关关系 ,相关系数为 0 .3 3 94(P<0 .0 1 )。淄博、济南、德州三市的水碘含量与饮水井深度之间呈正相关关系 ,相关系数分别为 0 .782 2、0 .5 989和 0 .40 70 (P<0 .0 1 )。聊城和济宁两市的水碘含量与饮水井深度之间无相关关系 (P>0 .0 5 )。结论 :水碘含量与饮水井深度之间有密切关系 ,水碘含量随饮水井深度的增加而增高 ,要寻找饮用适碘水源 ,不宜选择深层井

Studies on the relationship between trace element—iodine and depth of drinking water well

Objective:To study the relationship between trace element-iodine and depth o drinkin water well.Search normal water iodine layer.Methods We and made relative analysis between 423 portion of water iodine and depth of drinking water well,when we investigated the high iodine,based on the content of resident drinking water.Results On the whole,the water indine and the depthe of drinking water well were positive correlation.The relative coefficient is 0.3394 (P<0.01).At zibo,Jinan and Dezhou,the 3 cities'water iodine and depth of drinking water well are positive correlation.The relative coefficient are 0.7822?0.5989 and 0.4070(P<0.01).At the two city-Liaocheng and Jining,there are no correlation between the water iodine and depth of drinking water well (P>0.05).Conclusions There are close relationship between iodine and depth of drinking water well:the water iodine rises when the depth of drinking water well increase.To drink normal iodine water,and inadvisable to choose deep layer of well.
