ARGs abundance in WWTPC and WWTPA. (a) Total abundance of ARGs (RPKM) at different treatment stages of WWTPC. (b) Total abundance of ARGs (RPKM) at different treatment stages of WWTPA. (c) Top ten ARGs at different treatment stages of WWTPC. (d) Top ten ARGs at different treatment stages of WWTPA. (e) The total abundance of ARGs against the drug classes in WWTPC. (f) The total abundance of ARGs against the drug classes in WWTPA. The drug classes and their corresponding ARGs are represented by the colour gradient
