摘      要：Microplastic pollution is a global and ubiquitous environmental problem in the oceans as well as in the terrestrial *** examined the fate of microplastic polystyrene(MPS)beads in experimental soil in the presence and absence of symbiotic arbuscular mycorrhizal fungi(AMF)and simulated acid rain(SAR)to determine whether the combinations of these three factors altered the growth of white clover Trifolium *** found that MPS,SAR,or AMF added singly to soil did not alter *** growth or *** contrast,MPS and AMF together significantly reduced shoot biomass,while SAR and MPS together significantly reduced soil available phosphorus independent of AMF *** polystyrene,AMF,and SAR together significantly reduced soil NO_(3)^(-)-*** mycorrhizal fungi added singly also enriched the beneficial soil bacteria(genus Solirubrobacter),while MPS combined with AMF significantly enriched the potential plant pathogenic fungus *** mycorrhizal fungi inoculation with MPS increased the abundance of soil hydrocarbon degraders independent of the presence of *** addition,the abundance of soil nitrate reducers was increased by MPS,especially in the presence of AMF and ***,SAR alone increased the abundance of soil pathogens within the fungal community including antibiotic *** findings indicate that the coexistence of MPS,SAR,and AMF may exacerbate the adverse effects of MPS on soil and plant health.
