Abstract

The removal of volatile organic compounds (VOCs) from indoor environments using plants has attracted increasing attention as an effective natural mitigation strategy. In this study, five indoor plant species (Epipremnum aureum, Syngonium podophyllum, Spathiphyllum wallisii, Dieffenbachia and Monstera adansonii) grown hydroponically under controlled conditions were used to systematically quantify VOC removal by the leaves, whole cuttings and roots. Acetone, toluene, α-pinene, o-xylene, and limonene were selected as model indoor air pollutants. The results showed a marked variability in the leaf-based VOC removal efficiency among the plant species and pollutant, but complete VOC removal was never obtained. However, the whole plant cuttings supported complete and rapid (20–115 h) removals of all VOCs. Finally, the root-associated microorganisms were shown to significantly contribute to VOC removal, mainly through rhizodegradation. Overall, this study suggest that VOC removal by plant cuttings is due to the combined effects of physical adsorption and metabolic degradation mediated by plants and microorganisms, highlighting the synergistic role of plant morphological traits and rhizospheric microbial communities in phytoremediation.

在室内空气处理试验箱中阐明植物过滤器去除VOC的机制

利用植物从室内环境中去除挥发性有机化合物（VOCs）作为一种有效的自然减缓策略已引起越来越多的关注。本研究以五种室内水培植物（Epipremnum aureum, Syngonium podophyum, Spathiphyllum wallisii， Dieffenbachia和Monstera adansonii）为研究对象，在控制条件下系统地量化了叶片、整枝和根对VOC的去除。选择丙酮、甲苯、α-蒎烯、邻二甲苯和柠檬烯作为室内空气污染物模型。结果表明，不同植物种类和污染物的叶片VOC去除效率存在显著差异，但从未完全去除VOC。然而，整株扦插支持完全和快速（20-115 h）去除所有挥发性有机化合物。最后，与根相关的微生物被证明对挥发性有机化合物的去除有显著的贡献，主要是通过根降解。综上所述，植物扦插对VOC的去除是植物和微生物介导的物理吸附和代谢降解的综合作用，突出了植物形态特征和根际微生物群落在植物修复中的协同作用。
