Red wine is a rich source of phenolic antioxidants and is reported to reduce the risk of diabetes, cancer, Alzheimer's disease, and cardiovascular disease. To improve grape yields it is common practice in vineyards to use pesticides, such as fungicides and insecticides. This application presents a fast, easy, and cost-effective method for the determination of 24 pesticide residues in red wine using the QuEChERS extraction method (AOAC version), cleanup by dispersive solid-phase extraction (dSPE), followed by LC-MSMS analysis.
Contaminants of emerging concern (CEC) in the environment are generally described as compounds that are unknown or unrecognized, undetected or not routinely monitored, and represent a diverse group of chemicals that may pose a risk to human health and the environment. Due to limited analytical capability and available resources , monitoring of CECs has been focused on selected analytes rather than a holistic approach. We describe a new analytical method that can be used in the quantitative analysis of 61 targeted and 312 non-targeted CECs.
Pharmaceuticals and personal care products (PPCPs) and endocrine disrupting chemicals (EDCs) detected in surface and drinking waters, as well as in treated wastewater. They are an issue of increasing international attention due to potential environmental impacts. We developed an analytical method capable of determining PPCPs and their by-products in wastewater treatment plant (WWTP) samples. This workflow was applied in a survey of 35 permeate samples obtained from a pilot anaerobic membrane bioreactor (AnMBR).
Comprehensive assessment of the aquatic fate and effects of organic micropollutants is greatly hindered by the need to develop compound-specific methodologies prior to sampling and analysis. We descrbe a data-driven workflow, coupling high-resolution, accurate-mass (HRAM) mass spectrometry and highly sensitive online solid phase extraction (SPE) analysis that ensures complete characterization of organic pollutants in aquatic environments.
The Thermo Scientific UltiMate 3000 HPLC system is applied for the determination of 24 pesticide residues in red wine. The samples are prepared using Thermo Scientific HyperSep Dispersive SPE (QuEChERS), and the separation performed using a Thermo Scientific Accucore aQ HPLC column, with MS/MS detection.
