Nanoplastic–plant interaction and implications for soil health

Soil Use and Management, Journal Year: 2022, Volume and Issue: 39(1), P. 13 - 42

Published: Dec. 7, 2022

Abstract Nanoplastics (NPs) are accumulating in the soil environment at a rapid rate, which may cause serious consequences for ecosystems and human health. However, environmental behaviour toxicity of NPs soil–plant system remain poorly understood. This review summarizes current studies on NP–plant interactions to unravel uptake mechanisms phytotoxicity NPs. could be taken up by plant roots transported upwards through xylem all organs plant, even edible parts such as grain, thereby threatening The interaction with plants affects transport water nutrients. Besides, it induces significant oxidative stress leading inhibition physiological biochemical activities photosynthesis, thus adversely growth development. In addition, co‐transport other pollutants induce combined toxic effects. study also discussed potential mechanism based previous experience engineered nanomaterials. Finally, comprehensive assessment key challenges each area was presented, future perspectives offered.

Role of the Protein Corona in the Colloidal Behavior of Microplastics

Langmuir, Journal Year: 2023, Volume and Issue: 39(12), P. 4291 - 4303

Published: March 17, 2023

Microparticles of polyethylene and polypropylene are largely found in aquatic environments because they the most produced persistent plastic materials. Once biological media, covered by a layer molecules, so-called corona, mostly composed proteins. A yeast protein extract from Saccharomyces cerevisiae was used as system to observe interactions complex media. Proteins, acting surfactants providing hydrophilic surfaces, allow dispersion highly hydrophobic particles water stabilize them. After 24 h, microplastic quantity up 1 × 1011 per liter, whereas without protein, no remained solution. Label-free imaging corona synchrotron radiation deep UV fluorescence microscopy (SR-DUV) performed. In situ images were obtained, adsorbed quantity, coverage rate, heterogeneity determined. The stability kinetics suspensions measured light transmission using Turbiscan analyzer. Together, microscopic results demonstrate that can very efficiently microplastics solution provided quality is sufficient. Microplastic depends on different parameters such particle's intrinsic properties (size, density, hydrophobicity) formation changes particle wettability, electrostatic charge, steric hindrance. By controlling these with proteins, it becomes possible keep out solution, paving way for applications field pollution control remediation.
