2D Ni-Co bimetallic oxide nanosheets activate persulfate for targeted conversion of bisphenol A in wastewater into polymers

open access: yesEnvironment International
The selective removal of targeted pollutants from complex wastewater is challenging. Herein, a novel persulfate (PS)-based advanced oxidation system equipped with a series of two-dimensional (2D) bimetallic oxide nanosheets (NSs) catalysts is developed ...

Exposure to arsenic and cadmium promotes conjugative transfer of plasmid-borne antibiotic resistance genes among soil microbiota

open access: yesEcotoxicology and Environmental Safety
The spread of antibiotic resistance genes (ARGs) via horizontal gene transfer (HGT) poses a major global health threat. While cadmium (Cd) is known to influence ARG transfer in pure cultures, the effects of arsenic (As) and As-Cd co-exposure on plasmid ...

Urban Solid Waste Characterization of the Misiones Metropolitan Area

open access: yesRevista de Ciencia y Tecnología, 2022
This paper reports the behaviour of solid urban waste generation in the Metropolitan Area of Misiones, during a period of seven days. The waste analysed came from collection routes by household sampling points determined according to the land use and socioeconomic level of the population in the study area.
