Micro(nano)plastics sources, fate, and effects: What we know after ten years of research

Journal of Hazardous Materials Advances, Journal Year: 2022, Volume and Issue: 6, P. 100057 - 100057

The last decade has been transformative for micro(nano)plastic (MnP) research with recent discoveries revealing the extent and magnitude of MnP pollution, even in world's most remote places. Historically, while researchers recognized that plastic pollution was derived from land-based sources, it generally believed microplastic particles (i.e., fragments <5 mm) only a marine issue effects largely impacting biota. However, over progressed rapidly MnPs freshwater, snow, ice, soil, terrestrial biota, air found ocean spray. have now every environmental compartment on earth, within tissues gastrointestinal tracts thousands species, including humans, resulting harmful effects. 10 years also seen development new techniques analysis, re-purposing old technologies allowing us to determine down nano size range (<1 µm). This short review summarizes what key milestones major advances made nanoplastic environment, their fate, decade.

Evidence of free tropospheric and long-range transport of microplastic at Pic du Midi Observatory

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Dec. 21, 2021

Abstract The emerging threat of atmospheric microplastic pollution has prompted researchers to study areas previously considered beyond the reach plastic. Investigating range transport is key understanding global extent this problem. While microplastics have been discovered in planetary boundary layer, their occurrence free troposphere relatively unexplored. Confronting important because presence would facilitate over greater distances and thus potential more distal remote parts planet. Here we show evidence 0.09–0.66 particles/m 3 4 summer months from Pic du Midi Observatory at 2877 meters above sea level. These results exhibit true tropospheric microplastic, high altitude particles <50 µm (aerodynamic diameter). Analysis air/particle history modelling shows intercontinental trans-oceanic illustrating for aerosol transport.

Nanoplastics measurements in Northern and Southern polar ice

Environmental Research, Journal Year: 2022, Volume and Issue: 208, P. 112741 - 112741

Published: Jan. 19, 2022

It has been established that various anthropogenic contaminants have already reached all the world's pristine locations, including polar regions. While some of those contaminants, such as lead and soot, are decreasing in environment, thanks to international regulations, other novel emerge. Plastic pollution shown a durable pollutant, and, since recently, smaller plastics particles identified environments (air, water soil). Considerable research exists measuring 5 mm micrometre size range (microplastics). However, far less is known about debris fragmented sub-micrometre (nanoplastics). As these small light, it expected they most remote places on Earth, e.g. transported across globe by air movement. In this work, we used method based Thermal Desorption - Proton Transfer Reaction Mass Spectrometry (TD-PTR-MS) detect measure nanoplastics different types sampled from Greenland firn core (T2015-A5) sea ice Antarctica. We identify polyethylene (PE), polypropylene (PP), terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), Tire wear nanoparticles 14 m deep PE, PP PET Nanoplastics mass concentrations were average 13.2 ng/mL for samples 52.3 Antarctic ice. further discuss possible sources found at which likely involve complex processes plastic circulation (emission both land surface, atmospheric marine circulation).

Micro/nanoplastics effects on organisms: A review focusing on ‘dose’

Journal of Hazardous Materials, Journal Year: 2021, Volume and Issue: 417, P. 126084 - 126084

Microplastics have become predominant contaminants, attracting much political and scientific attention. Despite the massively-increasing research on microplastics effects organisms, debate of whether environmental concentrations pose hazard risk continues. This study critically reviews published literatures organisms within context "dose". It provides substantial evidence common occurrence threshold hormesis dose responses numerous aquatic terrestrial to microplastics. finding along with accumulated indicating capacity for recovery suggests that linear-no-threshold model is biologically irrelevant should not serve as a default assessing risks. The literature does provide sufficient supporting general conclusion doses cause adverse individual organisms. Instead, are smaller than toxicological more likely occur in environment may even induce positive effects, although ecological implications these remain unknown. also shows low can reduce whereas high increase negative other pollutants. mechanisms explaining findings discussed, providing novel perspective evaluating risks environment.
