Plastics have inundated the world, with microplastics (MPs) being small particles, less than 5 mm in size, originating from various sources. They pervade ecosystems such as freshwater and marine environments, soils, atmosphere. MPs, due to their size strong adsorption capacity, pose a threat plants by inhibiting seed germination, root elongation, nutrient absorption. The accumulation of MPs induces oxidative stress, cytotoxicity, genotoxicity plants, which also impacts plant development, mineral nutrition, photosynthesis, toxic accumulation, metabolite production tissues. Furthermore, roots can absorb nanoplastics (NPs), are then distributed stems, leaves, fruits. As NPs harm organisms ecosystems, they raise concerns about physical damage effects on animals, potential impact human health via food webs. Understanding environmental fate is essential, along strategies reduce release mitigate consequences. However, full understanding different plastics, whether traditional or biodegradable, development yet be achieved. This review offers an up-to-date overview latest known plastics plants.

Polyethylene microplastics alter root functionality and affect strawberry plant physiology and fruit quality traits

Journal of Hazardous Materials, Год журнала: 2024, Номер 470, С. 134164 - 134164

Strawberry, a globally popular crop whose fruit are known for their taste and health benefits, were used to evaluate the effects of polyethylene microplastics (PE-MPs) on plant physiology quality. Plants grown in 2-L pots with natural soil mixed PE-MPs at two concentrations (0.2% 0.02%; w/w) sizes (⌀ 35 125 µm). Plant physiological responses, root histochemical anatomical analyses as well biometric quality features conducted. subjected ⌀ μm/0.2% exhibited most severe terms CO2 assimilation due stomatal limitations, along highest level oxidative stress roots. Though no differences observed biomass, impact traits was MPs treatment resulting drop weight (–42%), soluble solid (–10%) anthocyanin contents (–25%). The smallest sized PE-MPs, adsorbed surface, impaired water status by damaging radical apparatus, which finally resulted alteration Further research is required determine if these alterations also occur other understand more deeply influence physio-chemistry. Anthropocene characterized an unprecedented surge plastic use, leading global microplastic (MP) proliferation terrestrial/aquatic environments. This study delves into topic MP interactions terrestrial plants, using spread (polyethylene [PE]) agricultural strawberry, strategic crop. Beyond impacts, this unveils potential strawberry PE-MP contamination soil. Herein demonstrated damage relation size concentration, providing scientific pieces evidence about risk exposure strawberries cultivated MP-polluted soil-system.

Abstract Microplastics, considered emerging contaminants, have been accumulating excessively within soil ecosystems, conferring potentially detrimental effects with respect to carbon turnover and pools. As a major participant in processes, microplastics affecting microorganisms may be one of the main agents dynamics. However, microbial metabolism processes through which affect dynamics remain unclear. Therefore, this study aimed assess impact variously sized (1300, 800, 100, 0.1 μm) polystyrene on metabolism. Soil all sizes invariably consistently affected metabolism, though nanomicroplastics (0.1 stressed more than micron‐microplastics. Furthermore, inhibited both use efficiency (CUE) respiration, exception being CUE 1300 μm treatment. microplastic particle size decreased, suppressive influence respiration was gradually lost, inhibitory effect increased steadily, shifted from extracellular intracellular, intracellular exhibiting higher toxicity microplastics. We used stoichiometric models provide precise projections features associated contamination, thereby enhancing understanding contamination cycle ecosystem.

With increasing plastic manufacture and consumption, microplastics/nanoplastics (MP/NP) pollution has become one of the world's pressing global environmental issues, which poses significant threats to ecosystems human health. In recent years, sharp researches have confirmed that MP/NP had direct or indirect effects on vegetative growth sexual process vascular plant. But potential mechanisms remain ambiguous. particles can be adsorbed and/or absorbed by plant roots leaves thus cause diverse This holistic review aims discuss plant, with special emphasis changes metabolic molecular levels. alter substance energy metabolism, as well shifts in gene expression patterns. Key aspects affected stress include carbon nitrogen amino acids biosynthesis hormone signal transduction, related genes, metabolism those involved pathogen defense. Additionally, provides updated insights into physiological responses plants exposed MP/NP, encompassing phenomena such seed/spore germination, photosynthesis, oxidative stress, cytotoxicity, genotoxicity. By examining impact from both perspectives, this sets stage for future investigations complex interactions between pollutants.
