UV filters as a driver of the antibiotic pollution in different water matrices.

31 Mar 2021-Journal of Environmental Management (J Environ Manage)-Vol. 289, pp 112389-112389
TL;DR: It is shown that the presence of UV filters either completely supresses or significantly alters the photodegradation of antibiotics in water, which may result in an imperfect prediction of the solar and UV light-based remediation of antibiotics, lead to improper classification in the environment and cause non-optimal chemical fate and transport model performance.

TL;DR: In this article , a vanadium pentoxide/graphitic carbon nitride (V2O5/C3N4) S-scheme with a facile approach was proposed for removing deleterious antibiotics residues in the water environment.
Abstract: Innovative solar-driven heterostructure photocatalysts are promising for removing deleterious antibiotics residues in the water environment. Herein, we prepared a vanadium pentoxide/graphitic carbon nitride (V2O5/C3N4) S-scheme with a facile approach. The heterostructure provides larger surface areas, promotes the separation and transfer of charge carriers, and offers abundant active sites for photocatalytic redox reactions. The composites were used to degrade amoxicillin (AMX) under solar light which attained a high removal efficiency (91.3%) and stability. Meanwhile, the photodegradation pathway of AMX was revealed by HPLC-MS/MS analysis and density functional theory (DFT) computations. Superoxide radicals evolved from conduction band of C3N4 and oxidative holes were generated from valence band of V2O5, which were confirmed by electron spin resonance experiments and selective radical quenching experiments. The V2O5/C3N4 S-scheme structure provides an internal electron channel at the interface and maintains the active sites with high potentials for photodegradation. Our work affords a robust V2O5/C3N4 S-scheme nanocomposites for sustainable water purification.

TL;DR: In this article , a visible-light-driven Z-type ZnAl-LDO/Ag2S heterojunction composite material with active phase Zn/Al LDO was used as an efficient catalyst for photocatalysis coupled with sulfate radical based-advanced oxidation processes (SR-AOPs) to degrade tetracycline hydrochloride (TC-HCl) under visible light.

TL;DR: The ecology and biogeochemistry of stream biofilms are described and the influence of physical and ecological processes on their structure and function are highlighted.
Abstract: Streams and rivers form dense networks, shape the Earth's surface and, in their sediments, provide an immensely large surface area for microbial growth. Biofilms dominate microbial life in streams and rivers, drive crucial ecosystem processes and contribute substantially to global biogeochemical fluxes. In turn, water flow and related deliveries of nutrients and organic matter to biofilms constitute major constraints on microbial life. In this Review, we describe the ecology and biogeochemistry of stream biofilms and highlight the influence of physical and ecological processes on their structure and function. Recent advances in the study of biofilm ecology may pave the way towards a mechanistic understanding of the effects of climate and environmental change on stream biofilms and the biogeochemistry of stream ecosystems.
