A Reliable Method for the Isolation and Characterization of Microplastics in Fish Gastrointestinal Tracts Using an Infrared Tunable Quantum Cascade Laser System
(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 ...
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 ...
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 ...
Misidentification of PVC Microplastics in Marine Environmental Samples
(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 ...
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
(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 ...
Effects of Zinc Oxide Nanoparticle Exposure on Human Glial Cells and Zebrafish Embryos
(MDPI, 2023-08-01)
[Abstract] Zinc oxide nanoparticles (ZnO NPs) are among the most widely used nanomaterials. They have multiple applications in cosmetics, textiles, paints, electronics and, recently, also in biomedicine. This extensive use ...
Weathering-Independent Differentiation of Microplastic Polymers by Reflectance IR Spectrometry and Pattern Recognition
(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, ...
Source Apportionment of PM10 and Health Risk Assessment Related in a Narrow Tropical Valley. Study Case: Metropolitan Area of Aburrá Valley (Colombia)
(Springer, 2023-04-05)
[Abstract] This study investigates spatio-temporal variations of PM10 mass concentrations and associated metal(oid)s, δ13C carbon isotope ratios, polycyclic aromatic hydrocarbons (PAHs), total organic carbon (TOC) and ...
Development of an Analytical Procedure to Analyze Microplastics in Edible Macroalgae Using an Enzymatic-Oxidative Digestion
(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 ...
Mixed-Mode Chromatography of Mixed Functionalized Analytes as the Homologues of Benzalkonium Chloride. Application to Pharmaceutical Formulations
(Elsevier, 2022-12-30)
[Abstract] In this work, a retention behavior based on mixed-mode reversed-phase (RP)/hydrophilic interaction liquid chromatography (HILIC) was observed for benzalkonium chloride (BAK) using a core-shell column functionalized ...
