Quality of drinking water was comprehensively studied in Fusui County of Guangxi, a high-incidence area for liver cancer. The results indicated pond water was polluted the most severely, well water the least, and river water intermediately. The chemical indicators for water pollution were levels of ammonia, nitrite, humic acid, suspended substances, chemical oxygen demand, and biological oxygen demand. Quality of drinking water was worse in high incidence area for liver cancer than that in low-incidence one. Mortality of liver cancer correlated positively with the levels of nitrite, humic acid, chemical oxygen demand, and so on. These results provided a basis for further studies on the etiology of liver cancer.
对广西扶绥县这个肝癌高发地区的饮用水水质进行了全面研究。结果表明，池塘水污染最为严重，井水污染最轻，河水污染程度居中。水污染的化学指标包括氨、亚硝酸盐、腐殖酸、悬浮物、化学需氧量和生化需氧量。肝癌高发地区的饮用水水质比低发地区的更差。肝癌死亡率与亚硝酸盐、腐殖酸、化学需氧量等的水平呈正相关。这些结果为进一步研究肝癌的病因提供了依据。
