Oilseed crops are greatly extended all over the world. Their high fat content can interfere during pesticide multiresidue analysis through liquid chromatography-tandem mass spectrometry (LC-MS/MS). This work aimed at overcoming this issue by developing and validating two QuEChERS-based methods for LC-MS/MS determination of 42 pesticides in fatty food matrices: olives sunflower seeds. Optimization extraction method was achieved following a 26-2 fractional factorial design highly...
The presence of pesticides in aquatic ecosystems poses significant risks to non-target organisms, necessitating monitoring and environmental risk assessment. This study aimed evaluate the dynamics a hydro-agricultural area with intensive agricultural practices, Mediterranean region (South Portugal). Seasonality location influenced pesticide numbers concentrations, highest levels observed during dry season. Triazines, phenylureas, organophosphates were predominant classes, terbuthylazine,...
Analytical methods based on QuEChERS and liquid chromatography-tandem mass spectrometry were developed for the determination of 42 polar semi-polar pesticides in three representative vegetable matrices, viz. corn, grapes alfalfa. A 26-2 fractional factorial experimental design was used to cost-effectively optimize extraction procedure. The optimal analytical approaches validated terms linearity, sensitivity, trueness, precision. Most target showed a relative recovery 70-120 %. Moreover,...
In regions where drought has become a common occurrence for most of the year and agriculture is main economic activity, development hydro-agricultural systems made it possible to improve water management. Despite this, intensification combined with climate change leads potential decrease in quality management practices are essential agro-environmental sustainability. The aim this study was assess irrigation ecological status reservoir (using support chemical parameters). results showed...
