  • 摘要: 以南京化学工业园的土壤为研究对象, 分析土壤中重金属Cr(Ⅵ)和Pb对赤子爱胜蚓(Eisenia fetida)生长及繁殖的影响.结果表明, 与对照组比较, 暴露28 d时, 较低浓度的Cr(Ⅵ)(4—8 mg·kg-1)和Pb(1000—1500 mg·kg-1)能促进赤子爱胜蚓的生长发育, 而较高浓度的Cr(Ⅵ)(32—64 mg·kg-1)和Pb(3000 mg·kg-1)则显著抑制赤子爱胜蚓的生长发育;赤子爱胜蚓的产茧量随着Cr(Ⅵ)和Pb浓度的升高被显著抑制, 其中, Cr(Ⅵ)抑制赤子爱胜蚓产茧量的EC50(半数有效浓度)、NOEC(无观察效应浓度)和LOEC(最低观察效应浓度)分别为22.86 (20.56—25.42)、8、16 mg·kg-1.Pb抑制赤子爱胜蚓产茧量的EC50、NOEC和LOEC分别为2280.34 (2200.90—2362.65)、1500、2000 mg·kg-1;与人工土壤中Cr(Ⅵ)和Pb对赤子爱胜蚓产茧量的28 d-EC50有显著性差异.
    Abstract: In the current study, the effects of chromium (Ⅵ) and lead on the growth and reproduction of Eisenia fetida in Nanjing soils were investigated. The results showed that: (1) compared with the control group, the growth of Eisenia fetida was promoted significantly in low concentration groups (4—8 mg·kg-1 chromium (Ⅵ))and 1000—1500 mg·kg-1 lead), while the body weight was inhibited significantly in high concentration groups (32—64 mg·kg-1 chromium (Ⅵ) and 3000 mg·kg-1 lead) after the exposure duration of 28 d. (2) the cocoon production was inhibited significantly with increasing chromium (Ⅵ) and lead concentrations. The EC50 (medium effective concentration), NOEL (No observed effect concentration) and LOEC (lowest observed effect concentration) values of cocoon production of chromium (Ⅵ) were 22.86 (20.56—25.42), 8 and 16 mg·kg-1, while the values of lead were 2280.34 (2200.90—2362.65), 1500 and 2000 mg·kg-1, respectively. (3) the 28 d-EC50 value of cocoon production in Nanjing soils was significantly different from the value in the artificial soils.
