A large scale multi-laboratory suspect screening of pesticide metabolites in human biomonitoring: From tentative annotations to verified occurrences
Elsevier (2022-08-05)Within the Human Biomonitoring for Europe initiative (HBM4EU), a study to determine new biomarkers of exposure to pesticides and to assess exposure patterns was conducted. Human urine samples (N = 2,088) were collected ... -
A Refined Nontarget Workflow for the Investigation of Metabolites through the Prioritization by in Silico Prediction Tools
American Chemical Society (2019-04-11)The application of nontargeted strategies based on high-resolution mass spectrometry (HRMS) directed toward the discovery of metabolites of known contaminants in fish is an interesting alternative to true nontarget screening. ... -
Avaluació de l'exposició i del risc de plaguicides a l'atmosfera en dues poblacions del País Valencià.
Ateneu de Natura (2015)L’avaluació del risc per a la població general front a la inhalació de plaguicides d’ús actual en l’agricultura ha sigut estudiada en una zona rural (Sant Jordi del Maestrat) i una remota (Morella) del País Valencià. L’avaluació ... -
Combined Use of GC-TOF MS and UHPLC-(Q)TOF MS To Investigate the Presence of Nontarget Pollutants and Their Metabolites in a Case of Honeybee Poisoning
American Chemical Society (2009)The combined use of gas chromatography (GC) and ultrahigh-pressure liquid chromatography (UHPLC), both coupled to time-of-flight mass spectrometry (TOF MS), has been explored in this work for the investigation of several ... -
Comprehensive investigation of pesticides in Brazilian surface water by high resolution mass spectrometry screening and gas chromatography–mass spectrometry quantitative analysis
Elsevier (2019)In this work, a comprehensive investigation on the occurrence of pesticides in the Paraná 3 hydrographic basin of Paraná State, Brazil, was made by application of wide-scope screening based on ultra-high performance liquid ... -
Comprehensive strategy for pesticide residue analysis through the production cycle of gilthead sea bream and Atlantic salmon
Elsevier (2017-07)Plant ingredients and processed animal proteins are alternative feedstuffs for fish feeds in aquaculture. However, their use can introduce contaminants like pesticides that are not previously associated with marine Atlantic ... -
Ecological risk assessment of pesticides in the Mijares River (eastern Spain) impacted by citrus production using wide-scope screening and target quantitative analysis
Elsevier (2021-02-02)The widespread use of pesticides, especially in agricultural areas, makes necessary to control their presence in surrounding surface waters. The current study was designed to investigate the occurrence and ecological risks ... -
Mobility and efficacy of abamectinand imidacloprid against Rhynchophorusferrugineus in Phoenix canariensis by differentapplication methods
Wiley (2014)BACKGROUND: Rhynchophorus ferrugineus is the most destructive pest of palms. As detection of early infestation stages isdifficult, preventive measures, mostly chemical control, are crucial. Stipe injection of insecticides ... -
Potential of atmospheric pressure chemical ionization source in GC-QTOF MS for pesticide residue analysis
John Wiley & Sons (2010-08)The potential applications of a new atmospheric pressure source for GC-MS analysis have been investigated in this work. A list of around 100 GC-amenable pesticides, which includes organochlorine, organophosphorus and ... -
Removal efficiency for emerging contaminants in a WWTP from Madrid (Spain) after secondary and tertiary treatment and environmental impact on the Manzanares River
Elsevier B.V. (2021-12-22)The effluents from wastewater treatment plants (WWTPs) can be an important contamination source for receiving waters. In this work, a comprehensive study on the impact of a WWTP from Madrid on the aquatic environment has ... -
Study on potential transfrnce of pesticides and polycyclic aromatic hidrocarbons from feed to farmed fish
Universitat Jaume I (2015-07-31)Throughout the last decades the huge demand on fish supply has led the world fish stocks to be over exploited. Aquaculture has appeared to be the solution for this situation, becoming the essential way of supplying the ... -
Wastewater-based epidemiology to assess pan-European pesticide exposure
Elsevier (2017)Human biomonitoring, i.e. the determination of chemicals and/or their metabolites in human specimens, is the most common and potent tool for assessing human exposure to pesticides, but it suffers from limitations such as ...
