长期饮用淦河温泉下游河水可使儿童头发中硒与硫的含量高出正常（指饮用自来水的）儿童约４倍，呈现高硫高硒体征，此体征儿童心率较慢，窦性心率不齐者增多，心房去极电位升高，心室去极和复极电位下降，Ｓ－Ｔ段移位例数和移位幅度均增加，心电图中的这些变化均在允许范围之内，但有些已接近病理边缘。红细胞数和血红蛋白量均略低于正常儿童。
Long-term consumption of Gan River Spa downstream of the river can make children’s hair content of selenium and sulfur higher than normal (referring to tap water) children about 4 times, showing signs of high sulfur and selenium, children with signs of this slow heart rate, sinus arrhythmia Increased, the atrial depolarization potential increased, the ventricular depolarization and repolarization potential decreased, the number of S-T segment shift and the amplitude of shift increased. All these changes in the ECG were within the allowable range, but some were close Pathological edge. Red blood cell count and hemoglobin were slightly lower than normal children.
