Analytical Detection of Sulfonamides and Organophosphorus Insecticide Residues in Fish in Taiwan

open access: yesMolecules, 2020
Exposure to residues of antibiotics (e.g., sulfonamides) and insecticides (e.g., organophosphorus insecticides) in aquacultured food can adversely affect humans and animals and thus affect public health globally.

Towards a Molecular Level Understanding of the Sulfanilamide-Soil Organic Matter-Interaction [PDF]

open access: yesScience of the Total Environment 559, 347 (2016), 2016
In-depth understanding of the sorption mechanisms of organic pollutants, like the antibiotic sulfanilamide (SAA), in soil requires a combined experimental and theoretical approach. Therefore, sorption experiments of SAA on well-characterized samples of soil size-fractions were combined with the modeling of SAA-soil-interaction via quantum chemical ...
