Antibiotics and Antibiotic Resistance Genes in Sediment of Honghu Lake and East Dongting Lake, China

Sediment is an ideal medium for the aggregation and dissemination of antibiotics and antibiotic resistance genes (ARGs). The levels of antibiotics and ARGs in Honghu Lake and East Dongting Lake of central China were investigated in this study. The concentrations of eight antibiotics (four sulfonamides and four tetracyclines) in Honghu Lake were in the range 90.00-437.43 μg kg-1 (dry weight (dw)) with mean value of 278.21 μg kg-1 dw, which was...
