本文应用紫露草微核技术检测合成洗涤剂的致突变性。结果发现,接触0.5%、1.0%和2.0%洗衣粉溶液6小时,紫露草微核率比对照组明显增高。洗衣粉接触浓度与紫露草微核率呈极显著正相关。结果提示,洗衣粉对生物体细胞拟有遗传毒性。 In this paper, rhododendron micronucleus technology was applied to detect the mutagenicity of synthetic detergents. The results showed that exposure to 0.5%, 1.0%, and 2.0% detergent powder solution for 6 hours significantly increased the micronucleus frequency of Radix in comparison with the control group. The contact concentration of laundry detergent was significantly positively correlated with the micronucleus frequency of the spiderweed. The results suggest that washing powder is intended to be genetically toxic to living cells.
