摘要
为研究东营市地下水碘化物的空间分布特征以及对环境和饮用水安全的影响,对域内的山前平原区和黄泛平原区分别布设了48个和47个调查点位。结果表明:东营市地下水碘化物质量浓度均值达到(0.247±0.263) mg/L,其环境质量呈现由南向北逐步恶化的变化趋势,超过90%的国土面积处于地下水环境质量标准Ⅳ类。山前平原区南部是东营市唯一具备可饮用地下水的区域,域内以适碘地区为主,缺碘地区和高碘地区分别位于区域东南部和第二次海侵古海岸线附近。总体上,可饮用地下水处于中等缺碘水平,海(咸)水入侵已成为影响可饮用地下水适碘地区范围的关键因素,需引起高度关注。地下水所处的环境地质概况、海(咸)水入侵和大气降水是影响碘化物空间分布的重要因素。
In order to investigate the spatial distribution characteristics of iodide for groundwater and its effects on environment and drinking water safety in Dongying,48 and 47 survey points were set up in the piedmont plain and Yellow River plain,respectively. The results indicated that the mean concentration of iodide for groundwater in Dongying was（0.247±0.263） mg/L and its environmental quality showed a trend of gradual deterioration from south to north,and more than 90% areas were in the groundwater quality standards of Ⅳ. The south of the piedmont plain was the only area with potable groundwater of Dongying,which was mainly included by suitable iodine area. While,iodine deficiency area and high iodine area were mainly distributed in the southeast of Guangrao and in the vicinity of the paleocoast line of the second marine transgression,respectively. As a whole,the potable groundwater was in the middle level of iodine deficiency,and the invasion of sea（saline） water had become a key factor impacting the scope of suitable iodine area with potable groundwater due to the existence of huge groundwater depression in the vicinity of Guangrao,which should be of great concern.The environmental geology had a significant influence on the distribution of iodide in Dongying. In addition, the sea（saline） water intrusion and atmospheric precipitation were also important factors affecting iodide spatial distribution.
