Quantitative analysis of nanoplastics in environmental and potable waters by pyrolysis-gas chromatography–mass spectrometry

Journal of Hazardous Materials, Journal Year: 2023, Volume and Issue: 464, P. 133013 - 133013

Published: Nov. 16, 2023

Nanoplastics are emerging environmental contaminants, but their presence in and potable water remains largely understudied due to the absence of quantitative analytical methods. In this study, we developed validated a pretreatment method that combines hydrogen peroxide digestion Amicon® Stirred Cell ultrafiltration (at 100 kDa, approximately 10 nm) with subsequent detection by pyrolysis gas chromatography-mass spectrometry (Pyr-GC/MS). This allows for simultaneous identification quantification nine selected nanoplastic types, including poly(ethylene terephthalate) (PET), polyethylene (PE), polycarbonate (PC), polypropylene (PP), poly(methyl methacrylate) (PMMA), polystyrene (PS), polyvinylchloride (PVC), nylon 6, 66, samples based on polymer-specific mass concentration. Limits ranged from 0.01 0.44 µg/L, demonstrating method's ability quantitatively detect nanoplastics samples. Most were detected at concentrations between 0.04 1.17 except PC, which was consistently below limit (<0.44 µg/L). The prevalent polymer components PE (0.10 - µg/L), PET (0.06 0.91 PP (0.04 0.79 PS 0.53 µg/L) nanoplastics. presented offers an accurate means identify, quantify, monitor complex It fills gaps our understanding pollution levels, providing valuable methodology crucial reference data future studies.

Detection and quantification of various microplastics in human endometrium based on laser direct infrared spectroscopy

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 906, P. 167760 - 167760

Published: Oct. 11, 2023

The pollution of microplastics (MPs) has received widespread attention with the increasing usage plastics in recent years. MPs could enter human body and exist circulatory system. Endometrium, rich blood vessels, acts as an essential role health female fertility. However, there is no study reporting exposure endometrium. We collected endometrium samples to detect presence qualitatively quantitatively via laser direct infrared. found that was a total 13 types existing samples, among which 6 special were both high abundance detection rate. these ranged from 0 117 particles/100 mg, median 21 mg. Most detected MPs, accounting for 88.35 %, small size (20-100 μm). Among small-size ethylene-acrylic acid copolymer ranked first while polyethylene accounted largest proportion large-size (100-500 Correlation analysis indicated significant relationship between age MP or BMI abundance. also designed questionnaire investigate lifestyle daily habits, aiming at revealing potential living habits. discovered some drinking habits chewing gum significantly correlated higher level exposure. For time, we identified clarified connections lifestyle. Further studies are still necessary explore more underlying information.

Quantitative image analysis of microplastics in bottled water using artificial intelligence

Talanta, Journal Year: 2023, Volume and Issue: 266, P. 124965 - 124965

Published: July 19, 2023

The ubiquitous occurrence of microplastics (MPs) in the environment and use plastics packaging materials result presence MPs food chain exposure consumers. Yet, no fully validated analytical method is available for microplastic (MP) quantification, thereby preventing reliable estimation level and, ultimately, assessment safety risks associated with MP contamination. In this study, a novel approach presented that exploits interactive artificial intelligence tools to enable automation analysis. An integrated analysis bottled water based on Nile Red staining fluorescent microscopy was developed validated, featuring partial interrogation filter automated image processing workflow Random Forest classifier, boosting speed. provided particle count, size distribution MPs. From these data, rough mass individual MPs, consequently concentration sample, could be obtained as well. Critical materials, performance characteristics, final applicability were studied detail. showed highly sensitive sizing down 10 μm, count limit detection quantification 28 85 items/500 mL, respectively.
