A Green Approach for the Automatic Quantitative Analysis of Additives in Plastic Samples Using In-Tube Extraction Dynamic Headspace Sampling Technique Coupled to GC-MS/MS
Concha-Graña, Estefanía; Moscoso Pérez, Carmen María; Fernández-González, V.; López-Mahía, P.; Muniategui, Soledad (Elsevier, 2024-05-08)[Abstract] Background: Many of the chemicals frequently used as additives have been recognised as hazardous substances, and therefore their analysis is necessary to evaluate plastic contamination risk. Additives analysis ... -
A Low-Cost System to Simulate Environmental Microplastic Weathering
Andrade-Garda, José Manuel; Fernández-González, V.; López-Mahía, P.; Muniategui, Soledad (Elsevier, 2019-12)[Abstract] Society concerns about the potential thread of microplastics into the environment call for detailed laboratory and field studies to assess their fate, in particular, their weathering. This can hardly be done in ... -
A Reliable Method for the Isolation and Characterization of Microplastics in Fish Gastrointestinal Tracts Using an Infrared Tunable Quantum Cascade Laser System
López-Rosales, Adrián; Andrade-Garda, José Manuel; Fernández-González, V.; López-Mahía, P.; Muniategui, Soledad (Elsevier, 2022-03-26)[Abstract] Societal and environmental concern due to frequent reports of microplastics in fish stomachs raised as they may accumulate along the trophic chain. The request for analysing microplastics in fish stresses two ... -
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)
Sánchez-Piñero, Joel; Moreda-Piñeiro, Jorge; Moscoso Pérez, Carmen María; Fernández-González, V.; Prada-Rodríguez, Darío; López-Mahía, P. (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 ... -
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, ... -
Impact of Weathering on the Chemical Identification of Microplastics From Usual Packaging Polymers in the Marine Environment
Fernández-González, V.; Andrade-Garda, José Manuel; López-Mahía, P.; Muniategui, Soledad (Elsevier, 2021-01-15)[Abstract] Most of the plastics produced worldwide are finally disposed into the environment, most of them being one-use plastic packaging. Once released, plastics may undergone degradation through several agents, such as ... -
Misidentification of PVC Microplastics in Marine Environmental Samples
Fernández-González, V.; Andrade-Garda, José Manuel; López-Mahía, P.; Muniategui, Soledad (Elsevier, 2022-04-30)[Abstract] Poly(vinylchloride), PVC, is the third most demanded polymer in Europe although its presence in marine ecosystems, surprisingly, is scarcely observed. This does not reflect neither its production nor its widespread ... -
Monitorization of Polyamide Microplastics Weathering Using Attenuated Total Reflectance and Microreflectance Infrared Spectrometry
Fernández-González, V.; Andrade-Garda, José Manuel; Ferreiro, Borja; López-Mahía, P.; Muniategui, Soledad (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 ... -
PAHs, Pesticides, Personal Care Products and Plastic Additives in Plastic Debris From Spanish Mediterranean Beaches
León, Víctor M.; García-Agüera, Inés; Moltó, Vicenç; Fernández-González, V.; Llorca-Pérez, Laura; Andrade-Garda, José Manuel; Muniategui, Soledad; Campillo, Juan Antonio (Elsevier, 2019-06-20)[Abstract] In this study the role of plastic debris as a pollution vector has been evaluated by determining the concentrations of hydrophobic organic contaminants in polymers from three Western Mediterranean coastal areas ... -
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 ... -
Weathering-Independent Differentiation of Microplastic Polymers by Reflectance IR Spectrometry and Pattern Recognition
Ferreiro, Borja; Andrade-Garda, José Manuel; Carlota, Paz-Quintáns; Fernández-González, V.; López-Mahía, P.; Muniategui, Soledad (Elsevier, 2022-07-07)[Abstract] The presence and effects of microplastics in the environment is being continuously studied, so the need for a reliable approach to ascertain the polymer/s constituting them has increased. To characterize them, ...
