Journal ArticleDOI

Chemical profiling of guarana seeds (Paullinia cupana) from different geographical origins using UPLC-QTOF-MS combined with chemometrics.

TL;DR: The metabolic profile of guarana from the two largest producing regions was investigated using UPLC-MS combined with multivariate statistical analysis, and the principal component analysis (PCA) showed significant differences between samples produced in the states of Bahia and Amazonas.
Journal ArticleDOI

Pesticides in fine airborne particles: from a green analysis method to atmospheric characterization and risk assessment.

TL;DR: A green sensitive sample preparation method is developed for determination of nine organophosphates, two pyrethroids, one carbamate, and one strobirulin in PM2.5 collected in a tropical coastal area in the Southern Hemisphere for the first time.
Journal ArticleDOI

Microwave-assisted digestion using diluted HNO3 and H2O2 for macro and microelements determination in guarana samples by ICP OES.

TL;DR: A microwave-assisted digestion procedure using diluted HNO3 and H2O2 was developed for multi-element determination in guarana samples by ICP OES and validated and applied for the determination of K, Ca, Mg, S, P, Cu, Fe, Mn and Zn in 72 Guarana seed samples from Bahia state.
Journal ArticleDOI

A rapid low-consuming solvent extraction procedure for simultaneous determination of 34 multiclass pesticides associated to respirable atmospheric particulate matter (PM2.5) by GC–MS

TL;DR: In this article, a miniaturized and low-consuming solvent extraction procedure has been developed for the simultaneous determination of 34 multiclass pesticides in PM2.5 samples, using sample masses as low as 321μg.
Journal ArticleDOI

Simple and effective dispersive micro-solid phase extraction procedure for simultaneous determination of polycyclic aromatic compounds in fresh and marine waters.

TL;DR: The proposed procedure was found to be comprehensive, precise, accurate, and suitable for determination of PACs in water samples.
