采用环境流行病学调查方法，以污染严重的黄河支流蟒河沿岸居民作为研究对象，以蟒河武陟段为污染区及与之相距１０ｋｍ的９个村庄为对照区对居民健康进行了调查研究。结果表明：虽然蟒河近岸区居民总死亡率与对照区无差异，但恶性肿瘤死亡率高于对照区，进一步对两区居民外周血淋巴细胞微核进行了测定，结果与恶性肿瘤的死亡率相吻合；近岸区居民免疫功能、神经行为功能、儿童生长发育均劣于对照区。该研究结果提示，蟒河的污染造成了沿岸居民健康损害。
Using the method of environmental epidemiology, the residents of the pythium along the polluted Yellow River tributary were selected as the research objects. The health status of residents was investigated by using the Wuhe section of the python and the nine villages 10km apart . The results showed that although the total mortality of residents in the coastal area of Manghe River was not different from that in the control area, the mortality rate of malignant tumors was higher than that of the control area. The micronuclei of peripheral blood lymphocytes were also determined in the two areas, Rate of coincidence; residents near the shore immune function, neurobehavioral function, children’s growth and development are inferior to the control area. The results suggest that the python river pollution caused the health damage of residents along the coast.
