据《健康报》报道中国预防医科院环境卫生监测所对江苏省丹阳市因患恶性肿瘤死亡者进行的回顾性调查最近完成。调查结果显示,各种恶性肿瘤死亡率中居前三位的是胃癌、食管癌、肝癌。这3种癌症死亡均与饮用沟塘水有关,且饮用的年限越长,危险度越大。 According to the “Health News” report, a retrospective survey conducted by the Institute of Environmental Sanitation Monitoring of the Chinese Preventive Medicine Academy on Danyang City, Jiangsu Province, who died of malignant tumors was recently completed. The survey results show that the top three cancer mortality rates are gastric cancer, esophageal cancer, and liver cancer. All three types of cancer deaths are associated with the drinking of ditch and pond water, and the longer the drinking period, the greater the risk.
