Direct and indirect photolysis of the antibiotic enoxacin: kinetics of oxidation by reactive photo-induced species and simulations
(2018-06-21)
The purpose of this study was to investigate the aqueous phase photochemical behavior of enoxacin (ENO), an antibiotic selected as a model pollutant of emerging concern. The second-order reaction rate constants of ENO with ...
Microplásticos: impacto ambiental de polímeros fotodegradados
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2020-02-03)
Plastics have been studied for their environmental impact, since when discarded in the environment they do not disappear. Over time they degrade and fragment into smaller pieces, reaching the microscale. When exposed to ...

El rol de la fotodegradación en el reciclado del carbono en un ecosistema semiárido de la Patagonia, ArgentinaThe role of photodegradation on carbon turnover in a semiarid ecosystem of Patagonia, Argentina
(2019-03-29)
La fotodegradación ha sido identificada recientemente como un mecanismo clave que controla las pérdidas de carbono (C) en ecosistemas áridos y semiáridos. Sin embargo, aún quedan muchas preguntas sin responder relacionadas ...
Photodegradation of norfloxacin adsorbed on clay and carbon-clay nanomaterials: an evaluation based on antimicrobial tests
(Académie Des Sciences, 2022-02)
The antibiotic norfloxacin was adsorbed on clay and carbon-clay nanocomposites (MD-210 and MDac3-210-500, synthesized by hydrothermal carbonization of dextrose) but maintained its antimicrobial activity once adsorbed. To ...
Solar UV radiation in a changing world: roles of cryosphere-land-water-atmosphere interfaces in global biogeochemical cycles
(Royal Society of Chemistry, 2019-01)
Global change influences biogeochemical cycles within and between environmental compartments (i.e., the cryosphere, terrestrial and aquatic ecosystems, and the atmosphere). A major effect of global change on carbon cycling ...
