| 摘 要： | 赫德莱Ｐｉａｏ体虫（Ｐｅｏｌｏｓｏｍａ ｈｅａｄｌｅｙｉ）为一种小型水栖寡毛类，行无性繁殖，室内培养容易，铬对其急性毒性试验结果为：２４ｈＬＣ５０为３．５５（３．１６－３．９０）ｍｇ／Ｌ，４８ｈＬＣ５０为１．８８（１．７７－２．０１）ｍｇ／Ｌ。低浓度慢怀试验结果为：无效应浓度（ＮＯＥＣ）为１０１μｇ／Ｌ，最大可接受浓度（ＭＡＥＣ）为１０１－１０２μｇ／Ｌ，慢性暴露１０天后种群可的最高浓度为２１０μ

| Abstract: | Aeolosoma headleyi, a small aquatic oligochaete with asexual reproduction was used to test the toxicity of Cr6+. In acute toxic test, 24h LC50 was 3. 55 (3. 16-3. 90) mg/L, 48h LC50was 1. 88 (1. 77-2. 01) mg/L, respectively. Chronic toxic test in low concentration growth was 101 mg/L, MAEC (maximum acceptable effect concentration) was 101-210 mg/L.The highest concentration in which the population growth could be recovered after 10 days exposure was 210 mg/L. A brief discussion on the possibility of this oligochaete to be used as bioassay organism was given. |
