摘要
广西扶绥是我国肝癌高发县之一,病区居民主要饮有机污染严重的塘水,塘水中的有机污染指标和某些有机组分均很高,而且与死亡率呈显著的正相关关系,而石灰岩层中的深井水则相反,水质好,死亡率很低。测试结果表明,塘水中存在亚硝胺类化合物,它们与死亡率有较好的平行关系。用这类塘水进行人体外周血淋巴细胞微核试验和细胞染色体畸变试验,证明其中有致突变的化学物质,通过换水可阻截水中有害有机物和致癌物进入人体,以达到增进居民健康,预防肝癌的目的。
Fusui is one of counties with high mortality of liver cancer in China. Pool water has been polluted seriously with high contents of organic pollutants is a main drinking water resource of the local residents. There is remarkable correlative relation between the contents of organic pollutants and the mortality of liver cancer. Nitrosamine in the pool water has been determined and it has parallel relation obviously with the mortality. The testes on cellular micronucleus and chromosome aberration of health human peripheral lymphocytes with prepared toxicant liquid of pool water indicate that there are some mutagenesis chemical materials in the pool water.
