磺胺类抗生素(Sulfonamide antibiotics,SAs)是一类以对氨基苯磺酰胺为基本结构的人工合成抗菌药品,在临床以及养殖业中被广泛应用,并随着养殖业废水以及有机肥施用于农田等途径进入自然环境和农田生态系统。
Variability and removal rate of tetracycline resistance genes in different wastewater treatment plan
Nowadays,wastewater treatment plants(WWTPs)may become a hot spot for antibiotics resistance genes(ARGs)due to the accumulation of antibiotics in sludge.
抗生素废水是一类色度深、含盐量高、悬浮物多的高浓度有机废水，主要有磺胺类、四环素类、大环内酯类、喹诺酮类等，成分极其复杂，因此需要开发一种绿色安全高效的废水处理方式。半导体MgFe2O4作为一种软磁n型半导体材料，具有带隙较小，光吸收性能好，耐腐蚀性且对环境无害的特点，广泛应用于多相催化、热疗、光催化剂、金属离子去除、吸附、传感器、偶氮染料降解等领域。
Environment pollution by antibiotics raised notable attention.In this paper,ZIF-8,a metal-organic framework material,was proposed as a potential absorbent to remove doxycycline hydrochloride(DCH)from
Coexistence of antibiotics and Zinc on the fate of pollutants removal,antibiotic resistance genes an
The existence of antibiotics and heavy metal co-pollution has become a major environmental issue.In this study,the three three-dimensional biofilm-electrode reactors(3D-BERs)powered by 0.8V voltage we
本研究以洞庭湖流域为典型，通过调查典型污染源(畜牧养殖废物/废水和城镇污水)中抗生素的分布，建立了典型流域抗生素排放源清单，通过实际检测数据估算流域内抗生素排放因子和排放量.结果显示，畜牧养殖废物/废水和城镇污水是洞庭湖流域主要的抗生素排放湖，前者以四环素类抗生素为主，总排放因子达363 mg/d/猪；后者则以大环内酯类抗生素最高，总排放因子约36.4 mg/天/千人.
环境中残留的抗生素一直被认为与环境中抗性基因(antibiotic resistance genes,ARGs)产生与传播有着密切联系,目前,学者们对于环境中抗生素与ARGs关系研究较多,但研究结果却不尽相同.本研究用磺胺对大肠杆菌(Escherichia coli,E.coli)毒性作用表征磺胺的胁迫作用,用突变和接合转移表征ARGs的产生与传播,测定了5种磺胺对E.coli的毒性、突变与质粒接
Antibiotics are widely detected in the environment and pose a serious threat to aquatic life and human health.Constructed wetlands are widely used in the purification of low-pollution water bodies,and
Antibiotics are characterized by accumulation and refractory properties and are widely detected in the environment.
