A lab-scale study using column experiments was conducted to provide knowledge on the biodegradation capacity of river hyporheic zone under flow intermittency. River water contamination simulated a mixture six compounds including pesticides (chloranthraniliprole, fluopyram and trifloxystrobin) pharmaceuticals (venlafaxine, amisulpride paroxetine) spiked at 1 µg/L level for degradation kinetic studies mg/L transformation products identification suspect non-target liquid chromatography high-resolution mass spectrometry approaches. The results suggested that intermittent flows stimulated three namely fluopyram, trifloxystrobin venlafaxine, showing large range profiles in batch water/sediment testing system. Biodegradation rate enhancement ascribed occurrence additional routes after desiccation period sediment. 16S rDNA sequencing revealed favored growth nitrifying denitrifying bacteria which could partially explain emergence new pathways most specifically those leading N-oxide derivatives. Identification also reductive were relevant this study, being dehydrogenation, dehalogenation, ether bond cleavage sulfone reduction into sulphide important reactions.

The removal of contaminants emerging concern and antibiotic resistance genes (ARGs) were investigated at pilot-scale with partially saturated vertical flow constructed wetland bioaugmented or not the Trichoderma asperellum T34 strain by means non-target liquid chromatography high-resolution mass spectrometry SmartChip™ Real-Time PCR methodological approaches. High variability in efficiency along a four-week experiment precluded to statically conclude that bioaugmentation was able significantly improve treatment performances for most CECs except diclofenac benzotriazole. Trichodermasp. grew fed secondary treated domestic wastewater but quick wash-out external secreted laccase peroxidase enzymes likely occurred. In contrast, there clear relationship between biodegradability as well sorption capacity identified compounds. As expected, biodegradation main driver accounting moderate when log Dow < 3. However, types reaction (hydrolysis vs oxidation reactions) key determinant rates rather substituents functional groups chemical structures leading different levels electronic steric hindrances. Sorption prevailed over only hydrophobic (log > 3) slowly biodegradable fate selected transformation products (TPs) could also be first time such treatments. formation persistence N-oxide TPs highlighted while which prone undergo further N-dealkylation hydroxylation partly eliminated. Noteworthy exception 14-hydroxyclarithromycin tended accumulate preserving an antimicrobial activity. Investigated treatments did reduce overall bacterial load flowing water. may have cause shift ARGs composition no statistical difference average rates.
