摘  要:
通过不同浓度的氟、汞、硒离子以及硒氟、硒汞离子不同浓度的混合液 ,分别诱发紫露草四分体微核效应。结果表明 ,在一定的剂量范围内 ,各处理物能显著诱发紫露草四分体微核率的提高 (P <0 .0 5或P <0 .0 1) ,具显著的遗传毒性效应。F-诱发的微核效应呈线性剂量反应关系 ,Hg2 +和Se4 +诱发的微核效应呈非直线关系。硒氟离子混合液与同浓度的F-相比 ,诱发的微核率显著下降 ,说明硒氟离子间呈明显的拮抗作用。而硒汞离子间能否产生拮抗作用 ,与Hg2 +浓度大小密切相关

摘  要:
Different concentrations of F -,Hg 2+ and Se 4+ or the mixed solutions of Se 4+ -F - or Se 4+ -Hg 2+ significantly ( P <0.05 or P < 0.01 ) increased tetrads in Tradescantia paludosa and had genetic toxicity. The micronucleus effect showed a linear relationship with the doasage of F - and a non-linear relationship with the dosage of Hg 2+ or Se 4+ . Compared with the F -, solution of similar concentration, the mixture of Se 4+ -F - gave a significantly lower frequency of micronucleus induction, suggesting an antagonism between the two ions. Whether antagonism between Hg 2+ and Se 4+ occurred was closely related to the concentartion of Hg 2+ .
