Occurrence of emerging contaminants, priority substances (2008/105/CE) and heavy metals in treated wastewater and groundwater at Depurbaix facility (Barcelona, Spain).
TLDR
Monitoring revealed a widespread occurrence of analysed compounds in groundwater, among them Codeine (analgesic), Ibuprofen (anti-inflammatory), Iopamidol, Iopromide (contrast agent) and Paraxanthine have only been detected in groundwater and are not present in water currently being injected in the deep aquifer. Expand
Monitoring of selected priority and emerging contaminants in the Guadalquivir River and other related surface waters in the province of Jaén, South East Spain.
TLDR
As could be expected, the total concentration of emerging contaminants is distinctly larger than that of priority pollutants, highlighting the importance of continuing with the study of their presence, fate and effects in aquatic environments. Expand
Chemical evaluation of contaminants in wastewater effluents and the environmental risk of reusing effluents in agriculture
Abstract Due to increasing interest in reusing wastewater in water-deficient regions, we suggest environmental risk assessment (ERA) as a suitable tool to evaluate potential risks from traceExpand
Sample treatment and determination of pesticide residues in fatty vegetable matrices: a review.
TLDR
This review addresses the main sample treatment methodologies for pesticide residue analysis in fatty vegetable matrices and emphasizes that sample preparation is a critical step, but also the determination method is, and cannot be treated separately from sample treatment. Expand
Determination of pesticide residues in fruit-based soft drinks.
TLDR
A screening method to search automatically for up to 100 pesticides in fruit-based soft drinks extracts based on the application of liquid chromatography-electrospray time-of-flight mass spectrometry (LC-TOF MS), which found relatively large concentration levels of pesticides in most of the samples analyzed. Expand
Direct monitoring of lipid oxidation in edible oils by Fourier transform Raman spectroscopy.
TLDR
The time-dependent intensity changes in certain Raman bands were compared to conventional parameters used to determine the extent of oxidation in oils, such as anisidine value and K(270), and showed good correlation. Expand
Screening of emerging contaminants and priority substances (2008/105/EC) in reclaimed water for irrigation and groundwater in a volcanic aquifer (Gran Canaria, Canary Islands, Spain).
TLDR
The widespread detection of high adsorption potential compounds, and the independence of concentration with origin and depths, indicates the existence of preferential flows phenomena as potential contamination route in volcanic fractured materials. Expand
Multi-residue method for the determination of over 400 priority and emerging pollutants in water and wastewater by solid-phase extraction and liquid chromatography-time-of-flight mass spectrometry.
TLDR
The developed method was applied to the determination of target analytes in real surface water and wastewater samples and performance was satisfactory with limits of quantification lower than 10ngL(-1) for the 44% of studied compounds. Expand
Determination of pesticide residues in olive oil and olives
Pesticide-residue determination in olive oil is becoming a very important and challenging issue. The present article provides a review of the most significant methods for determining pesticides inExpand
Accurate-mass databases for comprehensive screening of pesticide residues in food by fast liquid chromatography time-of-flight mass spectrometry.
TLDR
The development and evaluation of a rapid automated screening method for determining pesticide residues in food using liquid chromatography electrospray time-of-flight mass spectrometry (LC-TOFMS) based on the use of an accurate-mass database revealing as a convenient tool for the large-scale screening of pesticides in foodstuffs.
