Mass spectrometry-based multimodal approaches for the identification and quantification analysis of microplastics in food matrix

Frontiers in Nutrition, Journal Year: 2023, Volume and Issue: 10

Published: April 6, 2023

Microplastics (MPs) and nanoplastics (NPs) have become emerging contaminants worldwide in food matrices. However, analytical approaches for their determination yet to be standardized. Therefore, a systematic study is urgently needed highlight the merits of mass spectrometry (MS) based methods these applications.

Value for money: a cost-effectiveness analysis of microplastic analytics in seawater

Microplastics and Nanoplastics, Journal Year: 2024, Volume and Issue: 4(1)

Published: Feb. 10, 2024

Abstract The availability of many microplastic analysis methods is challenging for researchers and policy makers when tasked with choosing optimal their research question a given budget. In this study, cost-effectiveness in seawater was performed using survey data acquired from experts. Total cost per method determined accounting labour equipment costs, while effectiveness scored based on ability to confirm the plastic nature particles, minimum detectable particle size, other parameters. Results were validated discussed during two workshops scientists makers. resulting predictive tools allow identify most cost-effective specific scenarios, associated cost. They mark an important step towards more effective informed approach monitoring managing pollution marine environment, ultimately contributing protection ecosystems human health.

Strategies for the quantification and characterization of nanoplastics in AOPs research

Chemical Engineering Journal, Journal Year: 2024, Volume and Issue: 493, P. 152490 - 152490

Published: May 22, 2024

There is a growing interest in developing new targeted degradation technologies for the removal of micro- and nanoplastics (NPs) water, corresponding to increased public concerns regarding their potential negative impacts on urban water systems, consequently human life quality. Recently, Advanced Oxidation Processes (AOPs) have been proposed as promising treatment alternatives effective NPs water. However, selection appropriate analytical methods monitoring these oxidation tests remains challenge. Herein, feasibility different characterization strategies evolution upon was systematically studied using polystyrene (PS) particle sizes (D0 = 140, 252, 460, 909 nm) model plastic pollutants. To quantify Total Organic Carbon (TOC), Chemical Oxygen Demand (COD) turbidity measurements were assessed. Moreover, correlated size PS concentration by response surface. Among techniques employed characterize solid particles, transmission electronic microscopy (TEM) used evaluate morphology size. Alternatively, viability Dynamic Light Scattering (DLS), Nanoparticle Tracking Analysis (NTA) Atomic Force Microscopy (AFM) determine discussed. surface modifications explored Fourier-Transform Infrared Spectroscopy (FTIR). As proof concept, photo-Fenton investigated at ambient conditions fully characterized mentioned techniques.
