Microplastic stress in plants: effects on plant growth and their remediations

Frontiers in Plant Science, Год журнала: 2023, Номер 14

Опубликована: Авг. 11, 2023

Microplastic (MP) pollution is becoming a global problem due to the resilience, long-term persistence, and robustness of MPs in different ecosystems. In terrestrial ecosystems, plants are exposed MP stress, thereby affecting overall plant growth development. This review article has critically analyzed effects stress plants. We found that stress-induced reduction physical accompanied by two complementary effects: (i) blockage pores seed coat or roots alter water nutrient uptake, (ii) induction drought increased soil cracking MPs. Nonetheless, physiological under four excessive production ROS, alteration leaf root ionome, (iii) impaired hormonal regulation, (iv) decline chlorophyll photosynthesis. Considering that, we suggested targeting redox regulatory mechanisms could be beneficial improving tolerance plants; however, antioxidant activities highly dependent on species, tissue, type, dose. also indirectly reduces altering productivity. However, MP-induced negative vary presence surface functional groups particle sizes. end, utilization agronomic approaches, including application regulators, biochar, replacing plastic mulch with crop residues, diversification, biological degradation, ameliorate The efficiency these methods MP-type-specific dose-dependent.

Plastic debris is an established environmental menace affecting aquatic systems globally. Recently, microplastics (MP) and plastic leachates (PL) have been detected in vital human organs, the vascular system, vitro animal studies positing severe health hazards. MP PL found every conceivable ecosystem─from open oceans deep sea floors to supposedly pristine glacier lakes snow covered mountain catchment sites. Many documented impacts on a variety of organisms, whereby some exclusively focus microorganisms. Yet, specific primary producers not systematically analyzed. Therefore, this review focuses threats posed by MP, PL, associated chemicals phytoplankton, their comprehensive at organismal, community, ecosystem scales, endogenous amelioration. Studies MP- PL-impacted individual phytoplankton species reveal production reactive oxygen species, lipid peroxidation, physical damage thylakoids, other physiological metabolic changes, followed homo- heteroaggregations, ultimately eventuating decreased photosynthesis productivity. Likewise, analyses microbial community plastisphere show radically different profile compared surrounding planktonic diversity. The also enriches multidrug-resistant bacteria, cyanotoxins, pollutants, accelerating succession, changing microbiome, thus, diversity evolution. These cellular scales manifest changed dynamics with widespread bottom-up top-down effects biodiversity food web interactions. adverse effects─through altered nutrient cycling─have "knock-on" biogeochemical cycles greenhouse gases. Consequently, these affect provisioning regulating services. Our citation network (CNA) further demonstrate dire all trophic levels, thereby unsettling stability CNA points several emerging nodes indicating combined toxicity hazards phytoplankton. Taken together, our study shows that ecotoxicity particles placed ecosystems peril.

Soils in distress: The impacts and ecological risks of (micro)plastic pollution in the terrestrial environment

Ecotoxicology and Environmental Safety, Год журнала: 2023, Номер 269, С. 115807 - 115807

Plastics have revolutionised human industries, thanks to their versatility and durability. However, extensive use, coupled with inadequate waste disposal, has resulted in plastic becoming ubiquitous every environmental compartment, posing potential risks the economy, health environment. Additionally, under natural conditions, breaks down into microplastics (MPs<5 mm). The increasing quantity of MPs exerts a significant burden on soil environment, particularly agroecosystems, presenting new stressor for soil-dwelling organisms. In this review, we delve effects MP pollution ecosystems, specific attention (a) transport soils, (b) changes (c) interaction physical, chemical biological components soil. We aim shed light alterations distribution, activity, physiology growth flora, fauna microorganisms response MPs, offering an ecotoxicological perspective risk assessment plastics. are strongly influenced by intrinsic traits, including polymer type, shape, size abundance. By exploring multifaceted interactions between provide critical insights consequences contamination. Despite growing body research, there remain substantial knowledge gaps regarding long-term impact Our work underscores importance continued research efforts adoption standardised approaches address ensure sustainable future our planet.

Microplastics effects on wettability, pore sizes and saturated hydraulic conductivity of a loess topsoil

Geoderma, Год журнала: 2023, Номер 437, С. 116566 - 116566

Опубликована: Июнь 16, 2023

Environmental contamination with microplastics (MP, 0.1 µm – 5 mm diameter) potentially threatens various soil functions and agricultural production. In this study we evaluated the effects of MP on physical parameters (saturated hydraulic conductivity, water retention repellency) at concentrations (0.5 to 2 % w/w) that have been reported for farmland soils. Polyethylene terephthalate (PET) polystyrene (PS) three sizes ranging between 0.5 3 diameter, were mixed loess topsoil material from an agriculturally used Luvisol. Results show increasing concentration decreased saturated conductivity (ksat) compared control (without MP), irrespective type. The highest reduction ksat was found (2 %) largest size (approx. diameter). Compared control, addition significantly concentration. contrast, air capacity increased where strongest effect PET particles Soil repellency (measured as Wilhelmy Plate contact angles) a > 1 mm, while no observed lower smaller MP. conclusion, type, size, did affect key parameters, likely negatively influence plant growth in contaminated
