A Perspective on Plastics and Microplastics Contamination in Garden Soil in British Columbia, Canada

Pollutants, Journal Year: 2024, Volume and Issue: 4(1), P. 153 - 173

Published: March 12, 2024

Plastic contamination is commonly reported in urban and rural soils, as well fresh ocean waters. Canada’s government has attempted to limit the of single-use plastic by banning manufacturing selling specific types plastic. In British Columbia, current regulations governing commercial composting state that when compost less than 1% its dry weight representing foreign materials (including plastic), it can be sold used soils. However, due low density potential break down into microparticles, this amount may enough become toxic agricultural This paper studies garden soils summarizes how affect environment with a preliminary examination soil sample. The showed sample contained mainly low-density polyethylene, polyethylene polypropylene plastics (identified through ATR-FTIR) oxidized unoxidized forms come from hypothesizes could microplastic particles. order necessary modify treat differently other (glass, metal, wood).

Microplastic contamination in soils of urban allotment gardens (Toruń, Poland)

Journal of Soils and Sediments, Journal Year: 2024, Volume and Issue: unknown

Published: April 20, 2024

Abstract Purpose The study of microplastics (MPs) in soils is one the most important contemporary challenges as they negatively influence soil properties and may adsorb heavy metals pesticides. Recent data show that can be transported terrestrial food chain, endangering human animal health. In this pilot study, qualitative–quantitative analysis allotment gardens, which are mainly used for fruit vegetable production, was done. Also, sources environmental risks related to discussed. Methods We applied a four-step approach based on standard characteristics, density separation MPs from matrix, stereoscopic microscopy, Fourier infrared spectrometry (FTIR). Results all studied topsoils, high abundance heterogeneity were found. Microplastics like polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polyurethane (PUR), phenolic resins (PF), alkyd (AR) identified. Their not only activities allotments, but also deposition with wind or water cannot excluded. Conclusions revealed contamination gardens significant problem has been overlooked research. Considering amount people who use potential risk, by should monitored.

Abstract Plastic waste enters the oceans and soil is consumed by organisms humans. Some of ingested microplastics may remain in human body cause toxicity. We conducted a systematic review to estimate extent which humans are exposed through consumption performed quality assessment research results. searched for studies published up December 2023 included that reported on characteristics estimated intake microplastics. The tool previous was used food drinking water studies. 76 analysis, types foods were classified into seven categories: seafood, water, table salt, fruits vegetables, beverages, condiments, meat. daily via 0.0002–1,531,524 MP/day, with highest value bottled water. evaluated using quantitative assess reliability. 11.50 out 20 points 11.16 19 points. These results indicate closer score maximum, more reliable findings. can be as an indicator evaluating risks help reduce biases occur during process. This study confirmed exposure one million daily. Our emphasizes potential microplastic subsequent accumulation body; therefore, efforts needed life.

Micro-Nanoparticle Characterization: Establishing Underpinnings for Proper Identification and Nanotechnology-Enabled Remediation

Polymers, Journal Year: 2024, Volume and Issue: 16(19), P. 2837 - 2837

Published: Oct. 8, 2024

Microplastics (MPLs) and nanoplastics (NPLs) are smaller particles derived from larger plastic material, polymerization, or refuse. In context to environmental health, they separated into the industrially-created “primary” category degradation derivative “secondary” where exhibit different physiochemical characteristics that attenuate their toxicities. However, some particle types more well documented in terms of fate environment potential toxicological effects (secondary) versus industrial fabrication chemical characterization (primary). Fourier Transform Infrared Spectroscopy (FTIR/µ-FTIR), Raman/µ-Raman, Proton Nuclear Magnetic Resonance (H-NMR), Curie Point-Gas Chromatography-Mass Spectrometry (CP-gc-MS), Induced Coupled Plasma-Mass (ICP-MS), Nanoparticle Tracking Analysis (NTA), Field Flow Fractionation-Multiple Angle Light Scattering (FFF-MALS), Differential Scanning Calorimetry (DSC), Thermogravimetry (TGA), Mobility Particle [Sizing] (DMPS), Electron Microscopy (SEM), Transmission (TEM), X-ray Microspectroscopy (STXM) reviewed as part a suite methods for ascertainment distinguishment. addition, Optical-Photothermal (O-PTIR), Z-Stack Confocal Microscopy, Mueller Matrix Polarimetry, Digital Holography (DH) touched upon cutting-edge modes characterization. Organizations, like water treatment waste management industry, those groups bring awareness this issue, which direct contact with hydrosphere, can utilize these techniques order sense remediate polymer pollution. The primary goal review paper is highlight extent pollution introduce its effect on biodiversity planet while underscoring current field research. secondary involves illustrating theoretical avenues future research needs address optimize MPL/NPL remediation, utilizing nanotechnology, before sleeping giant problem awakens.
