Principal component analysis (PCA) of soil chemical properties (pH, available phosphorous (AP), electrical conductivity (EC), and total exchangeable cations (TEC), total exchangeable Na+ (Na), exchangeable K+ (K), exchangeable Mg2+ (Mg), and exchangeable Ca2+ (Ca)), bacterial richness and diversity indices (Chao 1 (Chao), ACE, Shannon (Shan), and InvSimpson (Inv)), and bacterial relative abundance (Acidobacteria (Aci), Actinobacteria (Act), Bacteroidetes (Bact), Candidatus Saccharibacteria (Cand), Chloroflexi (Chl), Cyanobacteria (Cya), Firmicutes (Firm), Gemmatimonadetes (Gem), Planctomycetes (Plan), Proteobacteria (Pro), and Verrucomicrobia (Ver)) with varied LDPE MP concentrations at 0, 0.1, 1, 3, 5, and 7% after 100 d of incubation.
