Microplastics (MPs), miniscule plastic particles measuring less than 5 mm in size, have become a concern terrestrial ecosystems, with primarily agricultural and wetland soils being the highest loadings. The adverse effect of MPs might lead to changes physicochemical biological characteristics soil including properties, microbial communities, plants, as well potential or affirmed correlations among them. Therefore, understanding risks effects MPs, particularly within soil-plant-microbe context is challenging subject substantial scientific inquiry. This comprehensive review focused on rhizosphere plant-microbe symbiotic relationships, implications for plant growth ecosystem-level nutrient fluxes. alter community composition, enzymatic activities rhizosphere, influencing availability uptake by plants. These can disrupt interactions, such mycorrhizal associations nitrogen-fixing symbioses, ultimately impacting cycling nutrients ecosystems.

Visualization of Labelled Micro- and Nanoplastics in Interaction with Algae, using Super-Resolution STED Microscopy and Fluorescence Lifetime Imaging

Environmental Toxicology and Chemistry, Journal Year: 2025, Volume and Issue: 44(3), P. 624 - 632

Published: Jan. 6, 2025

Abstract In contrast to microplastics, studying the interactions of nanoplastics (NPs) with primary producers such as marine microalgae remains challenging. This is attributed lack adequate visualization methods that can distinguish NPs from autofluorescent biological material algae. The aim this study was develop a method for labeling and visualizing nonfluorescent micro- (MNPs) various polymer types, shapes, sizes, in interaction producers, which are autofluorescent. A technique plastics refined, using swell incorporation commercial dye “IDye.” Comprehensive quality control measures, including toxicity, leaching, longevity tests, were applied ensure robustness method. Although stimulated emission depletion (STED) microscopy successfully enabled diverse labeled smaller than 200 nm, it could not organic microalgae, due overlapping excitation spectra photosynthetically active molecule chlorophyll-a. first advance field by coupling STED fluorescence lifetime imaging (FLIM). FLIM technique, based on differing lifetimes fluorescent signals, allowed us overcome challenge spectra. Our work only refines expands existing plastic protocols accommodate wide range but also introduces more precise between MNPs organisms. combined STED-FLIM approach provides reproducible reliable framework examining MNP impacts complex, ecologically relevant environments, particularly highlighting its potential investigating MNP–microalgae interactions.

Investigating the potential uptake of microplastic-derived carbon into a boreal lake food web using carbon-13 labelled plastic

FACETS, Journal Year: 2025, Volume and Issue: 10, P. 1 - 9

Published: Jan. 1, 2025

Microplastics degrade slowly over time, leaching carbon (C) that could be subsequently incorporated into aquatic food webs. Current estimates of microplastic degradation vary, and little is known about microplastic-derived C fate under natural environmental conditions. To investigate whether microplastics leach webs, we added isotopically enriched to Lake 378 at the Experimental Lakes Area in Ontario, Canada. In an ∼1100 L limnocorral (in situ open-bottom enclosure), 99% 13 C-labelled polystyrene (8–216 µm longest dimension) a nominal concentration 3268 particles/L. A second without served as negative control. Monthly measurements δ C-DIC C-DOC filtered water revealed no detectable from plastic. Compound-specific isotope analysis amino acids bulk plankton periphyton slight (0.5‰) enrichment C, within range variability for these organisms. Under conditions temperate oligotrophic lakes, likely very slow process was not possible detect this 4-month experiment. Future studies should focus on assessing realistic field scenarios improve pathways associated time scales.

Nanoarchitectonics influences the properties of objects at micro- and even macro-scales, aiming to develop better structures for protection product. Although its applications were analyzed in different areas, nanoarchitectonics food packaging-the focus this review-has not been discussed, best our knowledge. The (A) structural (B) functional hierarchy packaging is discussed here enhancement protection, extending shelf-life, preserving nutritional quality diverse products including meat, fish, dairy, fruits, vegetables, gelled items, beverages. Interestingly, structure design these often possess similar principles methods active packaging, gas permeation control, sensor incorporation, UV/pulsed light processing, thermal/plasma treatment. Here, nanoarchitechtonics serves as unifying component, enabling against oxidation, light, microbial contamination, temperature, mechanical actions. Finally, materials are an essential consideration particularly beyond commonly used polyethylene (PE), polypropylene (PP), terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC) plastics, with emphasis on biodegradable (polybutylene succinate (PBS), alcohol (PVA), polycaprolactone (PCL), polybutylene adipate co-terephthalate (PBAT)) well green edible (bio)-materials: polysaccharides (starch, cellulose, pectin, gum, zein, alginate, agar, galactan, ulvan, galactomannan, laccase, chitin, chitosan, hyaluronic acid, etc.). Nanoarchitechnotics eventually determines level sustainability processes. Marketing, safety, sustainability, ethics also context industrial viability consumer satisfaction.
