Occurrence and fate of eleven classes of antibiotics in two typical wastewater treatment plants in South China

Removal of antibiotics and antibiotic resistance genes from domestic sewage by constructed wetlands: Optimization of wetland substrates and hydraulic loading

“…The results from the present study clearly demonstrated that the detected seven antibiotics and all 18 target genes could be reduced by the mesocosm-scale CWs at relatively similar or even higher rates than conventional wastewater treatment plants (Lindberg et al, 2005;Li and Zhang, 2010;Gao et al, 2012;Jia et al, 2012;Chen et al, 2014;Zhou et al, 2013;Xu et al, 2015). In a word, optimized horizontal subsurface flow CWs may be a good choice applied as an effective treatment technology for removing antibiotics and ARGs in domestic sewage, and much more research is needed to make sure about the effect in practical application.…”

“…As to ETM-H 2 O, adsorption onto the substrates seems limited when compared to its total mass removals, suggesting biodegradation played a more important role. A previous study reported that the macrolides were mainly removed in the biological treatment unit (Zhou et al, 2013). It is worth noting that the removal rates of ETM-H 2 O by the mesocosm-scale CWs were quite higher than those reported in other treatment facilities (Gulkowska et al, 2008;Li and Zhang, 2010).…”

“…It is found that ARGs can be disseminated among bacteria via vertical and horizontal gene transfer, and distributed from human and animal sources to receiving environment . However, previous studies have showed incomplete removal of various antibiotics and ARGs in conventional municipal WWTPs (Li and Zhang, 2010;Gao et al, 2012;Jia et al, 2012;Zhou et al, 2013). It is thus essential to understand the removal mechanisms of antibiotics and ARGs in wastewater by other treatment technologies such as CWs.…”

Removal of antibiotics and antibiotic resistance genes from domestic sewage by constructed wetlands: Effect of flow configuration and plant species

“…Previous studies have reported wide detection of various antibiotics and ARGs in effluent and sludge from wastewater treatment plants (WWTPs), which could be a major cause for the ubiquitous occurrence of antibiotics and ARGs in various environmental compartments (Pruden et al, 2006;Durham et al, 2010;Li and Zhang, 2010;Tamminen et al, 2011;Gao et al, 2012;Jia et al, 2012;Su et al, 2012;Cheng et al, 2013;Coleman et al, 2013;Zhou et al, 2013). Therefore, a better wastewater treatment technology is needed for removing antibiotics and ARGs.…”

Development of novel graphene-like layered hexagonal boron nitride for adsorptive removal of antibiotic gatifloxacin from aqueous solution

“…Specifically, the fluoroquinolone antibiotics, which are poorly metabolized, have been shown to disrupt microbial respiration. The removal of fluoroquinolone antibiotics by conventional water and wastewater treatment technologies is generally incomplete (4). By now, many methods such as chemical oxidation, biodegradation, photodegradation, membrane filtration, and adsorption have been developed (5)(6)(7).…”
