Comparative analysis for five different classes of PM2.5 and PM10 samples. a Stratification of classes I–V for PM2.5 and PM10 samples. b, c PCoA analysis based on the Bray-Curtis distance metric of species abundance in PM2.5 (b) and PM10 (c) samples. d–g Taxonomic species number (d, e) and taxonomic Shannon index (f, g) for PM2.5 (d, f = red) and PM10 (e, g = blue) samples, respectively. h–k Gene number (h, i) and gene Shannon index (j, k) for PM2.5 (red) and PM10 (blue) samples, respectively. Asterisks denote Wilcoxon rank-sum test results (**P < 0.05; ***P < 0.01). l Pairwise Spearman’s correlation matrix of the portion of airborne microorganisms associated with different environmental sources correlating with PM concentrations (*adjusted P < 0.05; **adjusted P < 0.01)
