Quality Criteria for Microplastic Effect Studies in the Context of Risk Assessment: A Critical Review

Environmental Science & Technology, Journal Year: 2020, Volume and Issue: 54(19), P. 11692 - 11705

In the literature, there is widespread consensus that methods in plastic research need improvement. Current limitations quality assurance and harmonization prevent progress our understanding of true effects microplastic environment. Following recent development assessment for studies reporting concentrations biota water samples, we propose a method to assess effect studies. We reviewed 105 with aquatic biota, provided systematic overview their characteristics, developed 20 criteria four main categories (particle characterization, experimental design, applicability risk assessment, ecological relevance), protocol future particles, and, finally, used all information define weight evidence respect demonstrated mechanisms. On average, scored 44.6% (range 20–77.5%) maximum score. No study positively on criteria, reconfirming urgent better assurance. Most recommendations improvement relate avoiding verifying background contamination, improving environmental relevance exposure conditions. The majority (86.7%) evaluated particle characteristics properly, nonetheless it should be underlined by failing provide an entire experiment can become irreproducible. Studies addressed environmentally realistic polymer types fairly well; however, was mismatch between sizes tested those targeted when analyzing samples. far too many instances, suggest speculate mechanisms are poorly supported design data study. This represents problem decision-makers needs minimized research. papers, authors frame 10 as "suggested", whereas 7 them framed "demonstrated". When accounting according three these remained. These inhibition food assimilation and/or decreased nutritional value food, internal physical damage, external damage. recommend addresses higher priority.

How to Build a Microplastics‐Free Environment: Strategies for Microplastics Degradation and Plastics Recycling

Advanced Science, Journal Year: 2022, Volume and Issue: 9(6)

Published: Jan. 6, 2022

Microplastics are an emergent yet critical issue for the environment because of high degradation resistance and bioaccumulation. Unfortunately, current technologies to remove, recycle, or degrade microplastics insufficient complete elimination. In addition, fragmentation mismanaged plastic wastes in have recently been identified as a significant source microplastics. Thus, developments effective removal methods, well as, plastics recycling strategies crucial build microplastics-free environment. Herein, this review comprehensively summarizes eliminating from highlights two key aspects achieve goal: 1) Catalytic into environmentally friendly organics (carbon dioxide water); 2) catalytic upcycling monomers, fuels, valorized chemicals. The mechanisms, catalysts, feasibility, challenges these methods also discussed. Novel such photocatalysis, advanced oxidation process, biotechnology promising eco-friendly candidates transform benign valuable products. future, more effort is encouraged develop conversion products with efficiency, product selectivity, low cost under mild conditions.

The lack of standard approaches in microplastic research limits progress the abatement plastic pollution. Here, we propose and test rescaling methods that are able to improve alignment used research. We describe a method correct for differences size ranges as by studies reporting concentrations demonstrate how this reduces variation aqueous-phase caused differences. provide interchange between number, volume, mass using probability density functions represent environmental microplastic.
