| 英文摘要 | Ammunition-related activities have caused severe energetic compound (EC) contamination and pose serious risks to ecosystems. However, little is known regarding the spatial-vertical variations of ECs or their migration in soils at am-munition demolition sites. Although the toxic effect of some ECs to microorganisms have been reported through lab-oratory simulations, the responses of indigenous microbial communities to ammunition demolition activities are unclear. In this study, the spatial-vertical variations of ECs in 117 topsoil samples and three soil profiles from a typical ammunition demolition site in China were studied. Heavy contamination of ECs was concentrated in the top soils of the work platforms, and ECs were also detected in the surrounding area and nearby farmland. ECs showed different migration characteristics in the 0-100 cm soil layer of the different soil profiles. Demolition activities and surface run -off play critical roles in the spatial-vertical variations and migration of ECs. These findings suggest that ECs are able to migrate from the topsoil to the subsoil and from the core demolition area to further ecosystems. The work platforms exhibited lower microbial diversity and different microbiota compositions compared to the surrounding areas and farmlands. Using the random forest analysis, pH and 1,3,5-trinitrobenzene (TNB) were characterized as the most im-portant factors affecting microbial diversity. Network analysis revealed that Desulfosporosinus was highly sensitive to ECs and may be a unique indicator of EC contamination. These findings provide key information in understanding EC migration characteristics in soils and the potential threats to indigenous soil microorganisms in ammunition demo-lition sites. |
