This study investigates the <i>in vitro</i> adsorption efficiency of a tri-octahedral bentonite against aflatoxin B₁ (AFB1), zearalenone (ZEN), and fumonisin B₁ (FB1) in simulated gastric (pH = 1.2) and intestinal (pH = 6.8) fluids at 25 °C, the usual body temperature in aquaculture fish species. The binder was highly effective, removing over 98% of AFB1 from both media. FB1 was completely adsorbed at pH = 1.2, while its adsorption at pH = 6.8 reached a maximum of 46.3%. ZEN binding was consistent across both pH levels, ranging from 56.1% to 69.7%. Nine equilibrium isotherm functions were fitted to the experimental data to elucidate the adsorption mechanisms. A Sips model isotherm best characterized AFB1 adsorption in simulated gastric fluid, whereas that of ZEN was best described by the Freundlich model.

Glyphosate and glufosinate are both widely used herbicides. Glyphosate accounted for one-third of herbicide sales in Europe in 2017 and continues to raise health concerns, including its potential carcinogenicity. While the European Commission extended glyphosate's authorisation for another 10 years in 2023, concerns remain about its impact on biodiversity and human health. This study aimed to monitor the presence of glyphosate, glufosinate, and their metabolites in 100 samples of multifloral honey representing Italian production by analysis using IC-HRMS. Results indicated that 12% of honey samples contained glyphosate residues ranging from > LOQ to 45 ng g^-1, with the highest concentrations detected in the Puglia region. No sample exceeded the maximum residue levels set by EU regulations. Glufosinate and its metabolites were not detected in any samples.
