| 摘 要： | 研究氟离子与四价硒、氟离子与六价硒对大型溞的急性联合毒性，并采用相加指数法和毒性单位分析法评价其联合效应。结果表明，氟离子与两种价态硒的联合毒性都为拮抗作用；氟与四价硒的拮抗作用程度大于氟与六价硒的作用；氟离子与四价硒在不同浓度比例下混合作用，其拮抗作用程度不同，并呈一定规律性变化

| Abstract: | he joint toxicities of fluoride and selenite,fluoride and selenate to daphnia magna were studied in acute tests.Additive index method and toxic unit analysis approach were used to evaluate the joint toxic effects.The results showed that the combined toxicities were antagonism in both fluoride and selenite and fluoride and selenate tests.But the antagonistric degree of fluoride and selenite to D.magna was greater than that of fluoride and selenate.The combined action degree of fluoride and selenite varied with their different mixture ratios and changed in a regular way. |
