本研究首次报道了孟加拉国淡水鱼类和半咸水贝类养殖地表水中抗生素的发生、分布、生态和耐药性风险。在9种靶标中，有7种抗生素在鱼类养殖中检出，而在贝类养殖中检出4种。磺胺甲恶唑（SMX）的浓度（范围）和总体检出频率（nd-20.02 ng L-1和73%），甲氧苄啶（TMP）（nd-41.67 ng L-1和60%），泰乐菌素（TYL）（nd-39.34 ng L-1和60%），磺胺嘧啶（SDZ）（nd-17.97 ng L-1和53%），磺胺二甲嘧啶（SMT）（nd 11.71 ng L ~（-1），33%）、磺胺甲咪唑（nd 10.81 ng L ~（-1），40%）和青霉素G（nd 7.83 ng L ~（-1），7%）。在贝类水产养殖中，SMX（nd-16.77 ng L-1和67%）、TMP（nd-1139 ng L-1和20%）、TYL（nd-0.16 ng L-1和20%）和红霉素-H2O（ERY-H2O）（nd-3.91 ng L-1和20%）的浓度（范围）和总体检测频率分别为。目前的研究结果表明，有鳍鱼类养殖受到更多数量和浓度较高的抗生素污染。初步的生态风险和抗性风险评价结果表明，计算的风险因子（RQ）均小于1
The present study for the first time reports the occurrence, distribution, ecological and resistance risks of antibiotics in the surface water of freshwater finfish and brackish water shellfish aquaculture in Bangladesh. Among the nine targets, seven antibiotics were detected in finfish aquaculture, whereas four in shellfish aquaculture. The concentrations (ranges) and overall detection frequency of sulfamethoxazole (SMX) (nd-20.02 ng L-1 and 73%), trimethoprim (TMP) (nd-41.67 ng L-1 and 60%), tylosin (TYL) (nd-39.34 ng L-1 and 60%), sulfadiazine (SDZ) (nd-17.97 ng L-1 and 53%), sulfamethazine (SMT) (nd 11.71 ng L-1 and 33%), sulfamethizole (SMZ) (nd-10.81 ng L-1 and 40%) and penicillin G (PC_G) (nd 7.83 ng L-1, 7%) were found in finfish aquaculture. In case of shellfish aquaculture, the concentrations (ranges) and overall detection frequency were for SMX (nd-16.77 ng L-1 and 67%), TMP (nd-1139 ng L-1 and 20%), TYL (nd-0.16 ng L-1 and 20%) and erythromycin-H2O (ERY-H2O) (nd-3.91 ng L-1 and 20%). The present findings revealed that finfish aquaculture is more contaminated with the higher numbers and concentrations of antibiotics. The preliminary ecological and resistance risks assessment showed that the calculated risk quotients (RQs) were lower than one (RQs
