本文采用GDX-102型网状树脂收集水中有机物,对京杭大运河苏州段水城有机浓集物的致实变性进行了研究。在市区上游、下游及环城水域共设置采样点五个。进行了小鼠骨髓细胞和人外周血淋巴细胞微核试验和SCE试验,结果表明:小鼠骨髓细胞微核试验除上游采样点外其余各点均呈阳性;人外周血淋巴细胞微核试验和SCE试验各点均呈阳性,说明运河水中有机物具有致突变作用。
In this paper, GDX-102 mesh resin collected organic matter in the water, the Beijing-Hangzhou Grand Canal Shuicheng organic concentrated densification were studied. In the urban area, downstream and around the city set a total of five sampling points. Micronucleus test and SCE test of mouse bone marrow cells and human peripheral blood lymphocytes were carried out. The results showed that the micronucleus test of bone marrow cells in mice was positive except for the upstream sampling points. The micronucleus test of human peripheral blood lymphocytes and SCE test points were positive, indicating that the canal water has mutagenic effects of organic matter.
