Influence of reclaimed water discharge on the dissemination and relationships of sulfonamide, sulfonamide resistance genes along the Chaobai River, Beijing
Abstract
Reclaimed water threatens the ecological safety of the Chaobai River. SMX, TMP, and SDZ were the first three abundant antibiotics in the research area. SRGs and intI1 were widespread with high abundance after reclaimed water recharge. The SRGs values followed the sequence: Summer>autumn>spring>winter. Strong correlations were detected between SRGs and environmental factors.
