The extensive mining of bastnasite (CeFCO3) has caused pollution lanthanum (La), cerium (Ce), and fuorine (F) in the surrounding farmland soil, severely threatening safety soil ecosystem. However, interaction effects various chemical fractions La, Ce, F on composition microbial communities are unclear. In our study, high-throughput sequencing was performed based pot experiments four types combined soils, i.e., La + Ce (LC), (CF), (LF), (LCF), concentration ranges these three elements 20–240, 40–450, 150–900 mg kg–1, respectively. improved Tessier method used to investigate variations compositions. result showed residual form (La_RES) displayed restraint Abditibacteriota, leading its undetected level highest LC-polluted whereas promoted relative abundance microbes (Planctomycetota, Elusimicrobiota, Gemmatimonadota, Rozellomycota) by more than 80%; exchangeable organic-bound forms as well iron-manganese-bound were identified stress factors for sensitive bacteria (e.g., WS4, RCP2-54, Monoblepharomycota) CF-polluted soils; LF-polluted water-soluble most toxic effect Nitrospirota, FCPU426, decreased while La_RES GAL15, showing decline 80% LCF-polluted soils. Our study revealed both inhibition promotion element growth communities, providing a certain experimental evidence support further exploration treatment environmental elements.
