Evidence of internalized microplastics in mussel tissues detected by volumetric Raman imaging
(Elsevier, 2024-03)
Microplastics are a global ecological concern due to their potential risk to wildlife and human health. Animals ingest microplastics, which can enter the trophic chain and ultimately impact human well-being. The ingestion ...
What is in the fish? Collaborative trial in suspect and non-target screening of organic micropollutants using LC- and GC-HRMS
(Elsevier, 2023-10-25)
A collaborative trial involving 16 participants from nine European countries was conducted within the NORMAN network in efforts to harmonise suspect and non-target screening of environmental contaminants in whole fish ...
Development and evaluation of a comprehensive workflow for suspect screening of exposome-related xenobiotics and phase II metabolites in diverse human biofluids
(Elsevier, 2024-01-13)
Suspect and non-target screening (SNTS) methods are being promoted in order to decode the human exposome since a wide chemical space can be analysed in a diversity of human biofluids. However, SNTS approaches in the ...
Sample preparation for suspect and non-target screening of xenobiotics in human biofluids by liquid chromatography —High resolution tandem mass spectrometry
(Elsevier, 2023-11-29)
The concept of exposome covers all the exposures an individual suffers from conception to death,
which can be partially assessed through the monitoring of human biofluids. In there, target ana-
lytical approaches tend to ...
Sample preparation for suspect screening of persistent, mobile and toxic substances and their phase II metabolites in human urine by mixed-mode liquid chromatography
(Elservier, 2024-01-18)
Persistent, mobile and toxic substances have drawn attention nowadays due to their particular properties, but they are overlooked in human monitorization works, limiting the knowledge of the human exposome. In that sense, ...
Multitarget and suspect screening of antimicrobials in soil and manure by means of QuEChERS — liquid chromatography tandem mass spectrometry
(Springer Nature, 2023)
The present work aimed to develop an accurate analytical method for the simultaneous analysis of twenty-four antimicrobials in soil:compost and animal manure samples by means of ultra-high performance liquid chromatography ...
Evaluating membrane bioreactor treatment for the elimination of emerging contaminants using different analytical methods
(Elsevier, 2023-10-22)
Since wastewater treatment plants (WWTPs) were not originally designed to eliminate contaminants of emerging concern (CECs), alternative strategies like membrane bioreactor (MBR) technology are gaining importance in achieving ...
Validation of an LC-ESI-MS/MS for the quantitation of phosphodiesterase-5 inhibitors and their main metabolites in rat serum and brain tissue samples.
(Elsevier, 2012-105-1)
This work proposes a liquid chromatography-electrospray ionization ion trap mass spectrometry (LC-ESI-ITMS) method, for the quantification of sildenafil (SDF), tadalafil (TDF) and vardenafil (VDF) and their metabolites ...
Lunar Surface Resource Exploration: Tracing Lithium, 7 Li and Black Ice Using Spectral Libraries and Apollo Mission Samples
(MDPI, 2024-04-08)
This is an exercise to explore the concentration of lithium, lithium-7 isotope and the possible presence of black dirty ice on the lunar surface using spectral data obtained from the Clementine mission. The main interest ...
Geographical distribution of metals and metalloids along the estuary of the Oka River in the biosphere reserve of Urdaibai, Spain
(Elsevier, 2024-02)
Sediments sampled at the estuary of the Oka River in the biosphere reserve of Urdaibai, Spain were analyzed for trace elements. Sediments were collected at 45 points of the estuary and the concentration of 14 elements was ...
