Fate of antibiotics and antivirals in the aquatic environment and contamination by resistant bacteria

对流域内抗生素和抗病毒药物去向的调查表明，大部分药物是通过污水处理厂进入水体的。利用水生生物进行的生态毒性试验表明，在供试水生生物中，抗生素对藻类的毒性较高。至于耐药菌在流域内的去向，从河样中分离出的细菌中，氨苄西林耐药菌占较高比例，氨苄西林和磺胺甲恶唑耐药菌沿河流下游持续存在。

Survey on the fate of the antibiotics and antivirals in river basin showed that most of pharmaceuticals are entering into the river bodies through wastewater treatment plants. Ecotoxicity tests using aquatic organisms indicated that antibiotics have higher toxicity to algae among aquatic organisms tested. As for the fate of resistant bacteria in the river basin, ampicillin resistant bacteria were detected at high percentages among bacteria isolated from river samples and ampicillin and sulfamethoxazole resistant bacteria were persistent along the river downstream.
