作者对小清河重点污染源、河水及污灌区地下水、粮食、蔬菜进行了有机化合物的色—质联机定性分析和部分样品的液相色谱定量测定,开展了污灌对人体健康影响的流行病学调查,辅助以有机化合物的 Ames 致突变试验,研究了小清河及污灌区有机化合物污染和对人体健康影响的程度。结果表明:小清河重点工业污染源、河水、污灌区地下水、粮食、蔬菜中分别检出537、93、56、34和32种有机化合物,确认“三致”有毒有机物存在,污灌区人体健康水平有所下降。但 Ames 试验表明目前河水与地下水中有机化合物浓度尚没产生明显的致突变活性,此与流行病学调查的癌症和新生儿畸形发病率与对照村无显著性差异的结果相吻合。
The authors conducted color-mass qualitative analysis of organic compounds in groundwater, foodstuffs, and vegetables in the key pollution sources of Xiaoqing River, river water and sewage irrigation areas and the quantitative determination of some samples by liquid chromatography to carry out an epidemiological investigation on the impact of sewage irrigation on human health , Assisted with Ames mutagenicity test of organic compounds to study the degree of organic compound pollution and human health impact in Xiaoqinghe and Sewage Irrigation Areas. The results showed that 537,93,56,34 and 32 kinds of organic compounds were detected in the key industrial pollution sources of Xiaoqing River, groundwater, food and vegetables in the river and sewage irrigation areas, respectively, and the existence of “Sanzhi” toxic organic compounds was confirmed. The human health level in the sewage irrigation areas was The decline. However, the Ames test shows that there is currently no significant mutagenic activity of organic compounds in river and groundwater, which agrees well with the epidemiological investigation of the incidence of cancer and neonatal malformations in the control villages with no significant difference.
