摘　　要：为了解山东莱西店埠地区地下水的水化学特征,利用35个地下水的水样测试数据,分析了水化学基本特征,并评估了硝酸盐的健康风险。研究结果表明:区内地下水呈中性,阳离子以Ca^(2+)为主,阴离子以SO_(4)^(2-)为主,主要的水化学类型为SO_(4)-Ca型和Cl-Ca型水。研究区农业活动强烈,地下水中NO_(3)-N浓度普遍较高,最高值达到471 mg/L。基于健康风险评价模型,分别对成年人和儿童两类人群进行评价,结果显示长期直接饮用或接触店埠地区的高硝酸盐地下水存在较高的健康风险,且儿童的风险要远高于成人。To understand the hydrochemical characteristics of groundwater in the Dianbu area of Laixi,Shandong Prov⁃ince,the basic characteristics of hydrochemistry were analyzed and the health risk of nitrate was assessed using the test data of 35 groundwater samples.The results show that the groundwater in the area is neutral,with Ca^(2+) as the main cation and SO_(4)^(2-) as the main anion.The main hydrochemical types are SO_(4)·Ca and Cl·Ca.Agricultural activities are intense in the study are⁃a,and the concentration of NO_(3)-N in groundwater is generally high,with the highest value reaching 471 mg/L.Based on the health risk evaluation model,adults and children were evaluated respectively.The results showed that long-term direct drink⁃ing or exposure to high nitrate groundwater in the Dianbu area has higher health risks,and the risk of children is much higher than that of adults.
