TL;DR: The proposed method showed to be simple, easy, and adequate for high-throughput analysis of a large number of samples per day at low cost.
Journal ArticleDOI
Analytical quality assurance in veterinary drug residue analysis methods: matrix effects determination and monitoring for sulfonamides analysis.
Rodrigo Barcellos Hoff,Rodrigo Barcellos Hoff,Gabriel Rübensam,Louise Jank,Fabiano Barreto,Maria do Carmo Ruaro Peralba,Tânia Mara Pizzolato,M. Silvia Díaz-Cruz,Damià Barceló +8 more
TL;DR: Qualitative and quantitative methods for estimation of matrix effects such as post-column infusion, slopes ratios analysis, calibration curves (mathematical and statistical analysis) and control chart monitoring are discussed using real data.
Journal ArticleDOI
High-throughput method for macrolides and lincosamides antibiotics residues analysis in milk and muscle using a simple liquid-liquid extraction technique and liquid chromatography-electrospray-tandem mass spectrometry analysis (LC-MS/MS).
Louise Jank,Louise Jank,Magda Targa Martins,Juliana Bazzan Arsand,Tanara Magalhães Campos Motta,Rodrigo Barcellos Hoff,Fabiano Barreto,Tânia Mara Pizzolato +7 more
TL;DR: A fast and simple method for residue analysis of the antibiotics classes of macrolides and lincosamides was developed and validated for cattle, swine and chicken muscle and for bovine milk and is able to be applied in routine analysis.
Journal ArticleDOI
Presence of antibiotic resistance genes and its association with antibiotic occurrence in Dilúvio River in southern Brazil.

TL;DR: A methodology for quantification of 40 antibiotics of 5 different classes, in river water, by SPE-LC-MS/MS was validated and revealed the presence of ARGs in all samples, with the highest concentration found for blaTEM.
Journal ArticleDOI
Simultaneous determination of eight antibiotics from distinct classes in surface and wastewater samples by solid-phase extraction and high-performance liquid chromatography–electrospray ionisation mass spectrometry
TL;DR: In this article, a reliable multiclass method was developed and validated for the determination of eight antibiotics from distinct classes (sulfonamides, macrolides, fluoroquinolones, tetracyclines, cephalosporins and dihydrofolate reductase inhibitors) in wastewater and surface water from Porto Alegre, Brazil.
