(Elsevier, 2021-03-14)[Abstract] In this work two sensitive areas of the Spanish coast located in the Atlantic (Ria de Vigo) and Mediterranean (Mar Menor lagoon) have been studied regarding their contamination by phthalates, organotin compounds ... -
Modeling the Natural Gas Knocking Behaviour Using Gas-Phase Infrared Spectra and Multivariate Calibration
(Elsevier, 2021-04-01)[Abstract] To assess the knocking properties of natural gas (NG) when it is used as fuel for vehicles is vital to optimize the design and functioning of their motors. Analytical efforts in this field are needed as the ... -
Polycyclic Aromatic Hydrocarbons Analysis in Tea Infusions and Tea Beverages Using Membrane Assisted Solvent Extraction
(Elsevier, 2021-04-16)[Abstract] Membrane Assisted Solvent Extraction (MASE) was applied as an extraction and enrichment technique of polycyclic aromatic hydrocarbons (PAHs) from tea infusions and fruit/herbal-tea beverages. PAHs have been ... -
Development of a Fast and Efficient Method to Analyze Microplastics in Planktonic Samples
(Elsevier, 2021-04-22)[Abstract] Microplastics (MPs) affect plankton (a basis of the trophic chain) and planktivorous fish can ingest them through food confusion or by trophic transmission. Consensus to determine MPs in plankton is lacking and, ... -
Evolution of Gaseous and Particulate Pollutants in the Air: What Changed after Five Lockdown Weeks at a Southwest Atlantic European Region (Northwest of Spain) Due to the SARS-CoV-2 Pandemic?
(MDPI, 2021-04-27)[Abstract] Due to the exponential growth of the SARS-CoV-2 pandemic in Spain (2020), the Spanish Government adopted lockdown measures as mitigating strategies to reduce the spread of the pandemic from 14 March. In this ... -
Intercomparison and characterization of 23 Aethalometers under laboratory and ambient air conditions: procedures and unit-to-unit variabilities
(Copernicus Publications, 2021-04-30)[Abstract]: Aerosolized black carbon is monitored worldwide to quantify its impact on air quality and climate. Given its importance, measurements of black carbon mass concentrations must be conducted with instruments ... -
A Synthetic Quality Index to Evaluate the Functional Stability of Soil Microbial Communities After Perturbations
(Elsevier, 2021-05-28)[Abstract] Soil stability includes both resistance, the ability to withstand a perturbation or stress, and resilience, the ability to recover to pre perturbation levels. The functional stability of soil microbial communities ... -
Monitorization of Polyamide Microplastics Weathering Using Attenuated Total Reflectance and Microreflectance Infrared Spectrometry
(Elsevier, 2021-07-10)[Abstract] The EU goal to reduce marine plastic litter by ca. 30% by 2020 stressed the need to deploy analytical methods to ascertain the polymeric nature of a residue. Furthermore, as plastics age under natural conditions ... -
Development and Validation of a Multi-Pollutant Method for the Analysis of Polycyclic Aromatic Hydrocarbons, Synthetic Musk Compounds and Plasticizers in Atmospheric Particulate Matter (PM₂.₅)
(Elsevier, 2021-07-18)[Abstract] Exposure to atmospheric particulate matter (PM) associated pollutants is a global concern due to the risk posed in human health after inhalation. In this study, a simple and sensitive multi-residue method is ... -

(Elsevier, 2021-07-28)[Abstract] Quality control of natural gas frequently relies on off-line slow standardized chromatographic techniques. Previous implementations of new measurement approaches focused of synthetic mixtures without extensive ... -
Oral Bioavailability Reveals an Overestimation of the Toxicity of Polycyclic Aromatic Hydrocarbons in Atmospheric Particulate Matter
(Springer Nature, 2021-11-19)[Abstract] Polycyclic aromatic hydrocarbons (PAHs) in atmospheric particulate matter have adverse effects on human health, yet total PAH concentrations should overestimate the toxicity compared to the bioavailable amount ... -
Adsorption of Pesticides and Personal Care Products on Pristine and Weathered Microplastics in the Marine Environment. Comparison Between Bio-Based and Conventional Plastics
(Elsevier, 2022)[Abstract] The hydrophobicity of persistent organic pollutants (POPs) makes them adsorb on microplastics in the marine environment, affecting their distribution, persistence, or their transfer to the trophic chain. Fragrances ... -
New Ways for the Advanced Quality Control of Liquefied Natural Gas
(MDPI, 2022-01-04)[Abstract] Currently, gas chromatography is the most common analytical technique for natural gas (NG) analysis as it offers very precise results, with very low limits of detection and quantification. However, it has several ... -
