| 中文摘要: |
| 为探讨抗虫耐除草剂转基因玉米ZZM030对水生生物的安全性，以浮游动物大型蚤（Daphnia magna）为研究对象，使用转基因玉米ZZM030及其非转基因对照亲本玉米祥249（X249）饲喂大型蚤28 d，检测转基因玉米ZZM030对大型蚤生长和繁殖的影响。28 d测试结果显示，与亲本X249组大型蚤相比，ZZM030玉米组大型蚤在存活率、体长、首次抱卵时间、首次产幼蚤时间、首次产幼蚤数、新生幼蚤总数等参数上没有显著性差异。28 d饲喂结果表明抗虫耐除草剂玉米ZZM030与X249非转基因亲本玉米对大型蚤具有同样的安全性。 |

| To assess the potential risk that transgenic maize poses to aquatic organisms, the effects of the genetically modified (GM)maize ZZM030 were examined on the water flea Daphnia magna, as a model species for ecotoxicological studies. In a 28-day study, D. magna were experimentally fed a basal diet of ground flour from ZZM030 or its parental maize X249 at 1.5 g·L-1 per individual per day. Overall, D. magna fed ZZM030 and X249 showed comparable survival, body size, maturity time, first brood time, first brood size, and total number of offspring, with no significant differences observed for any of the above parameters. This study suggests that the GM maize ZZM030 is a safe food source for D. magna with substantial equivalence to its parental non-GM maize. |
