Modeling the Natural Gas Knocking Behaviour Using Gas-Phase Infrared Spectra and Multivariate Calibration

Ponte, Santiago; Andrade-Garda, José Manuel; Vázquez, Cristina; Ferreiro, Borja; Cobas, Carlos; Pérez, Andrés; Rey, María; Vales Fernández, Carlos; Pellitero, José; Santracruz, Blanca; Muniategui, Soledad; López-Mahía, P.; Shu, Bo; Bettin, Helga; Klaus, Daniela; Anders, Bert; Betz, Marius; Kühne, Ulf; Meier, Christian; Eilts, Peter (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 ...

Multi-Class Organic Pollutants in Atmospheric Particulate Matter (PM2.5) From a Southwestern Europe Industrial Area: Levels, Sources and Human Health Risk

Sánchez-Piñero, Joel; Novo-Quiza, Natalia; Moreda-Piñeiro, Jorge; Turnes-Carou, Isabel; Muniategui, Soledad; López-Mahía, P. (Elsevier, 2022-08)

[Abstract] The occurrence of 50 multi-class pollutants comprising 18 polycyclic aromatic hydrocarbons (PAHs), 12 phthalate esters (PAEs), 12 organophosphorus flame retardants (OPFRs), 6 synthetic musk compounds (SMCs) and ...

Development of an Analytical Procedure to Analyze Microplastics in Edible Macroalgae Using an Enzymatic-Oxidative Digestion

López-Rosales, Adrián; Andrade-Garda, José Manuel; López-Mahía, P.; Muniategui, Soledad (Elsevier, 2022-08-30)

[Abstract] Besides being food and a refuge to marine species, macroalgae are a powerful and renewable economic resource. However, they may introduce microplastics (MPs) in the trophic chain. We developed a reliable analytical ...

On the Influence of VOCs on New Particle Growth in a Continental-Mediterranean Region

Gómez-Moreno, Francisco J.; Alonso, Elisabeth; Díaz Ramiro, Elías; Coz, Esther; Molero, Francisco; Núñez, Lourdes; Palacios, Magdalena; Barreiro, Marcos; Fernández, Javier; Salvador, Pedro; Piñeiro-Iglesias, M.; López-Mahía, P.; Borrás, Esther; Vera, Teresa; Muñoz, Amalia; Tritscher, Torsten; Schmitt, Sebastian; Artíñano, Begoña (IOP Sciencie, 2022-12-30)

[Abstract] A field campaign has been performed in the Madrid region to study the VOC influence in the growth of new particles in ambient air. A number of instruments have been deployed to characterize the main pollutant ...

Fast Quality Control of Natural Gas for Commercial Supply and Transport Utilities

Ferreiro, Borja; Andrade-Garda, José Manuel; López-Mahía, P.; Muniategui, Soledad; Vázquez, Cristina; Pérez, Andrés; Rey, María; Vales Fernández, Carlos (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 ...

New Ways for the Advanced Quality Control of Liquefied Natural Gas

Ferreiro, Borja; Andrade-Garda, José Manuel; Paz-Quintáns, Carlota; López-Mahía, P.; Muniategui, Soledad (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 ...

Development of a Fast and Efficient Method to Analyze Microplastics in Planktonic Samples

López-Rosales, Adrián; Andrade-Garda, José Manuel; Grueiro-Noche, Gloria; Fernández-González, V.; López-Mahía, P.; Muniategui, Soledad (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, ...

Phthalates, Organotin Compounds and Per-Polyfluoroalkyl Substances in Semiconfined Areas of the Spanish Coast: Occurrence, Sources and Risk Assessment

Concha-Graña, Estefanía; Moscoso Pérez, Carmen María; Fernández-González, V.; López-Mahía, P.; Gago, Jesús; León, Víctor M.; Muniategui, Soledad (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 ...

Oral Bioavailability Reveals an Overestimation of the Toxicity of Polycyclic Aromatic Hydrocarbons in Atmospheric Particulate Matter

Sánchez-Piñero, Joel; Gómez-Meijide, Paula; Concha-Graña, Estefanía; Moreda-Piñeiro, Jorge; Muniategui, Soledad; López-Mahía, P. (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 ...
