Sb is typically accompanied by As in sulfide ores in Sb mining areas, which are found worldwide ( Li et al., 2017 Chang et al., 2022). China is the world’s largest producer of Sb, especially southwest China, which accounts for 80% of global Sb production ( Xu et al., 2020). Sb is carcinogenic and excessive Sb exposure can damage the respiratory, cardiovascular, and urinary systems ( Nishad and Bhaskarapillai, 2021 Liu et al., 2022 Zhou et al., 2022). Both Sb and As have been listed as priority pollutants by the European Union and the Environmental Protection Agency of the USA and restricted pollutants by China ( Wei et al., 2015a Chang et al., 2022 Yang et al., 2022 Zhou et al., 2022). Results: (1) A total of 513,546 sequences were obtained, and the majority belonged to Glomeraceae, followed by Diversisporaceae, Paraglomeraceae, Acaulosporaceae, Gigasporaceae, and Archaeosporaceae (2) the affinity between AMF and plants was mainly related to plant species ( F = 3.488, p = 0.022 < 0.050), which was not significantly correlated with the total Sb (TSb) and total As (TAs) in soil (3) the AMF spore density was mainly related to the available nitrogen, available potassium, and total organic carbon (4) The effect of soil nutrients on AMF community composition (total explanation: 15.36%) was greater than that of soil Sb and As content (total explanation: 5.80%) (5) the effect of TAs on AMF community composition (λ = −0.96) was more drastic than that of TSb (λ = −0.21), and the effect of As on AMF community composition was exacerbated by the interaction between As and phosphorus in the soil and (6) Diversisporaceae was positively correlated with the TSb and TAs.ĭiscussion: The potential impact of As on the effective application of mycorrhizal technology should be further considered when applied to the ecological restoration of Sb- and As-contaminated areas.Īntimony (Sb) and arsenic (As) have similar chemical characteristics ( Anawar et al., 2011 Yu et al., 2021) and occur ubiquitously in the environment at trace levels ( Johnston et al., 2020 Xu et al., 2020 Li Y. Methods: Morphological and molecular identification were applied to study the AMF community composition in Sb- and As-contaminated areas, and the main influencing factors of AMF community composition in Sb- and As-contaminated areas were explored. Introduction: The lack of systematic investigations of arbuscular mycorrhizal fungi (AMF) community composition is an obstacle to AMF biotechnological applications in antimony (Sb)- and arsenic (As)-polluted soil. 4College of Environmental Science and Engineering, Tongji University, Shanghai, China.3Chinese Research Academy of Environmental Sciences, Beijing, China.2College of Environment, Hohai University, Nanjing, China.1State Key Laboratory of Environmental Criteria and Risk Assessment, Chinese Research Academy of Environmental Sciences, Beijing, China.Yidong Mi 1,2 Chao Xu 3 Xinru Li 1,4 Min Zhou 1,2 Ke Cao 1 Cuimin Dong 1 Xuemei Li 1 Ningning Ji 1 Fanfan Wang 1 Hailei Su 1 Xuesong Liu 1 Yuan Wei 1*
