Microplastics and nanoplastics have become emerging particulate anthropogenic pollutants rapidly turned into a field of growing scientific public interest. These tiny plastic particles are found in the environment all around globe as well drinking water food, raising concerns about their impacts on human health. To adequately address these issues, reliable information ambient concentrations microplastics is needed. However, micro- nanoplastic extremely complex diverse terms size, shape, density, polymer type, surface properties, etc. While particle different media can vary by up to 10 orders magnitude, analysis such samples may resemble searching for needle haystack. This highlights critical importance appropriate methods chemical identification, quantification, characterization nanoplastics. The present article reviews advanced representative mass-based particle-based microplastics, with focus sensitivity lower-size limit detection. advantages limitations methods, complementarity comprehensive discussed. A special attention paid approaches Finally, an outlook establishing harmonized standardized analyze challenging contaminants presented, perspectives within beyond this research

Underestimated health risks: polystyrene micro- and nanoplastics jointly induce intestinal barrier dysfunction by ROS-mediated epithelial cell apoptosis

Particle and Fibre Toxicology, Journal Year: 2021, Volume and Issue: 18(1)

Published: June 7, 2021

Micro- and nanoplastic pollution has become a global environmental problem. Nanoplastics in the environment are still hard to detect because of analysis technology limitations. It is believed that when microplastics found environment, more undetected nanoplastics around. The current "microplastic exposure" fact mixture micro- exposures. Therefore, biological interaction between organisms among different sizes should not be neglected.We measured biodistribution three polystyrene (PS) particles (50 nm PS, PS50; 500 PS500; 5000 PS5000) under single co-exposure conditions mice. We explored underlying mechanisms by investigating effects on major components intestinal barrier (the mucus layer, tight junctions epithelial cells) four intestine segments (duodenum, jejunum, ileum colon) amounts both PS500 PS5000 increased they were co-exposed with PS50 for 24 h These due primarily permeability mouse intestines. also confirmed there was combined toxicity This manifested as causing severe dysfunction than caused or alone.

In addition, mice after 28-day repeated dose exposure.There intestines, which ROS-mediated Considering most recent studies have been conducted using particle size, health risks exposure may underestimated.

Unsustainable plastic production, use and mismanagement has resulted in increased global pollution subsequent degradation into micro(nano)plastics the environment threatening sustainability. Micro(nano)plastic is pervasive caused widespread ecological impacts globally, including greenhouse gas emissions, contributing to climate change. Although downstream strategies curb exist, they are ineffective face of current production waste generation which still outpacing existing regulations. Thus, international community recognized a more holistic approach required reduce micro(nano)plastic pollution. This critical review highlights studies showing that unsustainable increasing all environmental compartments, yet few have documented successful prevention or removal techniques. offers constructive criticism some help advance ambitious reduction targets for transition towards sustainable plastics future.

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.

Since the launch of United Nations (UN) Sustainable Development Goals (SDGs) in 2015, SDGs have been widely adopted by governments and corporations an effort to improve their sustainability. There are 17 SDGs, comprising 169 targets, which measurable against 247 unique indicators. Despite pervasive global pollution from (micro)plastics, there is only one indicator (14.1.1b) under Goal 14, specifically related reducing impacts (micro)plastics. Reliable reporting monitoring SDG indicators present challenges for organizations implement, may be further exacerbated nature (micro)plastic if not properly monitored across these This review focused on recent literature provide a critical overview key (micro)plastics as they undermine implementation sustainable strategies action plans required achieve UN SDGs.
