摘　　要：佳乐麝香(HHCB)是近几年来受关注较多的药品与个人护理品(PPCPs)类新型污染物之一,土壤微生物数量的变化是反映外来物质对土壤生态系统影响的重要指标。采用土壤微宇宙法对HHCB污染下细菌、放线菌和真菌数量的变化进行研究,结果发现,土壤中添加HHCB处理70d内,HHCB污染对土壤细菌数量影响是先抑制后促进作用,对放线菌数量影响是抑制作用,对真菌数量的影响是促进作用,对菌种毒害顺序为:放线菌>细菌>真菌。在HHCB土壤污染风险评价研究中,真菌对HHCB具有较强耐受性。放线菌对HHCB污染很敏感,可将放线菌作为土壤HHCB污染的早期预警指标。Galaxolide（HHCB ）, one type of PPCPs, as one of new environmental pollutants, has been attracted great attentions in latest years, Microbial changes in the number is an important indicator of foreign substances on soil ecosystems. Changes in the number of bacteria, actinomycetes and fungi were studied by using soil microcosm method under HHCB pollution. Results suggested that the HHCB pollution impact was promoted after the first inhibition on soil bacteria quantities, and was inhibition on actinomycetes quantities, and was promoted on fungi quantities, the order of toxic with strains is actinomycetes〉bacteria〉fungi,in soil added HHCB treatment 70 days. Fungi had a strong tolerance on HHCB, but actinomycetes was very sensitive to it, so actinomycetes can be used as early warning indicators of soil HHCB pollution.
