| 摘 要： | 研究了Ｃｕ＋＋、Ｚｎ＋＋对褶皱臂尾轮虫（Ｂｒａｃｈｉｏｎｕｓｐｌｉｃａｔｉｌｉｓ）的急性毒性影响。实验温度２５±１℃，轮虫对Ｃｕ＋＋的污染相当敏感，Ｃｕ＋＋２４ｈ半致死浓度为２４ｈＬＣ５０＝１４．４７μｇ／Ｌ～２１．９３μｇ／Ｌ；Ｚｎ＋＋２４ｈ半致死浓度为２４ｈＬＣ５０＝３．４０４ｍｇ／Ｌ～４．５４９ｍｇ／Ｌ。

| Abstract: | With neoated rotifer Brachionus plicatilis BZ]taken as the tested animal, the toxic effect of Cu and Zn ions on rotifer was examined at 25. The results show that rotifer was very sensitive to Cu ion with the 24h LC50s ranging from 14.47 g/L to 21.93 g/L, while rotifer was exposed to Zn ion with the 24h LC50s from 3.404 mg/L to 4.549 mg/L under the same experimental conditions. |
