Pigment microparticles and microplastics found in human thrombi based on Raman spectral evidence

Journal of Advanced Research, Journal Year: 2022, Volume and Issue: 49, P. 141 - 150

Published: Sept. 15, 2022

Environmental microparticle is becoming a global pollutant and the entire population increasingly exposed to microparticles from artificial materials. The accumulation of including microplastics its subsequent effects need be investigated timely keep sustainable development human society.This study aimed explore environmental particles in thrombus, pathological structure blood circulation system.Patients receiving cardiovascular surgical operations were screened twenty-six thrombi collected, digested filtered. Non-soluble enriched on filter membrane then analyzed identified with Raman Spectrometer. associations particle status (presence or absence) number thrombus clinical indicators examined. One strict quality control-particle detection system was designed eliminate contaminations.Among thrombi, sixteen contained eighty-seven ranging 2.1 26.0 μm size. each ranged one fifteen median reaching five. All found irregularly block-shaped. Totally, twenty-one phthalocyanine particles, Hostasol-Green particle, low-density polyethylene microplastic, which synthetic materials, thrombi. rest included iron compounds metallic oxides. After adjustment for potential confounders, significantly positive association between platelet levels detected (P < 0.01).This provides first photograph spectrum evidence A large non-soluble material could accumulate arteries, suggesting that risk exposure under-estimated re-evaluation health urgently needed. There will series reports assessing humans future this research provided clues research.

Rapid single-particle chemical imaging of nanoplastics by SRS microscopy

Proceedings of the National Academy of Sciences, Journal Year: 2024, Volume and Issue: 121(3)

Published: Jan. 8, 2024

Plastics are now omnipresent in our daily lives. The existence of microplastics (1 µm to 5 mm length) and possibly even nanoplastics (<1 μm) has recently raised health concerns. In particular, believed be more toxic since their smaller size renders them much amenable, compared microplastics, enter the human body. However, detecting imposes tremendous analytical challenges on both nano-level sensitivity plastic-identifying specificity, leading a knowledge gap this mysterious nanoworld surrounding us. To address these challenges, we developed hyperspectral stimulated Raman scattering (SRS) imaging platform with an automated plastic identification algorithm that allows micro-nano analysis at single-particle level high chemical specificity throughput. We first validated enhancement narrow band SRS enable high-speed single nanoplastic detection below 100 nm. then devised data-driven spectral matching imposed by sensitive narrow-band achieve robust determination common polymers. With established technique, studied plastics from bottled water as model system. successfully detected identified major types. Micro-nano concentrations were estimated about 2.4 ± 1.3 × 10

Environmental Degradation of Microplastics: How to Measure Fragmentation Rates to Secondary Micro- and Nanoplastic Fragments and Dissociation into Dissolved Organics

Environmental Science & Technology, Journal Year: 2022, Volume and Issue: 56(16), P. 11323 - 11334

Understanding the environmental fate of microplastics is essential for their risk assessment. It to differentiate size classes and degradation states. Still, insights into fragmentation mechanisms primary secondary micro- nanoplastic fragments other products are limited. Here, we present an adapted NanoRelease protocol a UV-dose-dependent assessment size-selective quantification release down 10 nm demonstrate its applicability polyamide thermoplastic polyurethanes. The tested cryo-milled polymers do not originate from actual consumer but handled in industry therefore representative polydisperse occurring environment. suitable various types microplastic polymers, measured rates can serve parameterize mechanistic models. We also found that matched same ranking weathering stability as corresponding macroplastics dissolved organics constitute major rate mass loss. results imply previously formed further degrade water-soluble with measurable enable modeling approaches all compartments accessible UV light.
