| 摘 要： | 通过现场采样及室内培养分析,研究了黔西南滥木厂铊矿化区沉积物和土壤中的微生物区系组成及生物量与重金属的相关性。结果表明:与背景区相比,矿区内的河流沉积物、土壤中的微生物区系组成及其生物量了明显变化,沉积物中细菌、真菌、放线菌分别减少了89%,86%和99%,在土壤样品中则分别减少了78%,66%和88%,且三大微生物敏感性大小分别表现为放线菌>细菌>真菌。样品中的微生物生物量与重金属的含量呈明显的负相关关系,特别是与铊的的相关系数均低于-0.5,反映出铊对微生物的毒害作用。 |

| Abstract: | Microbial populations and major microorganism groups were assayed in sediments and soils polluted by tailings from a Hg-Tl mine at Lanmuchang,Guizhou Province.The results showed that the microbial populations and major microorganism groups had changed significantly in samples polluted by Tl.Compared with the background samples,the number of microbial populations(bacteria,fungi and actinomycetes) decreased accordingly with increasing contamination of heavy metals,by 89%,86%,99% in the river sediments and by ... |
