Interactive impacts of microplastics and arsenic on agricultural soil and plant traits

The Science of The Total Environment, Год журнала: 2023, Номер 912, С. 169058 - 169058

The ability of microplastics (MPs) to interact with environmental pollutants is currently great concern due the increasing use plastic. Agricultural soils are sinks for multipollutants and safety biodegradable MPs in field conditions questioned. However, still few studies have investigated interactive effects between metals on soil-plant system agricultural soil testing crops human consumption. In this work, we tested effect plant parameters two common MPs, non-degradable plastic low-density polyethylene polymer polylactic acid at different sizes (<250 μm 250–300 μm) association arsenic (As). Lettuce (Lactuca sativa L.) was used as a model small-scale experiment lasting 60 days. Microplastics As explained 12 % 47 total variance, respectively, while their interaction 21 %, suggesting higher toxic impact than MPs. Plant growth promoted by alone, especially when were added (+22 %). did not affect nutrient concentrations roots leaves. enzyme activities variable depending time exposure (with larger immediately after exposure), type size On contrary, co-application MP As, although it change amount bioavailable short medium term, resulted significant decrease lettuce biomass (−19 %) root concentrations, applied. Generally, determined plant-soil toxicity. This work provides insights into risk copollution its phytotoxic crops. mechanisms joint toxicity need further investigation, under long-term experiments.

Micro/nanoplastics pollution poses a potential threat to soil health

Global Change Biology, Год журнала: 2024, Номер 30(8)

Опубликована: Авг. 1, 2024

Abstract Micro/nanoplastic (MNP) pollution in soil ecosystems has become a growing environmental concern globally. However, the comprehensive impacts of MNPs on health have not yet been explored. We conducted hierarchical meta‐analysis over 5000 observations from 228 articles to assess broad parameters (represented by 20 indicators relevant crop growth, animal health, greenhouse gas emissions, microbial diversity, and pollutant transfer) whether depended MNP properties. found that exposure significantly inhibited biomass germination, reduced earthworm growth survival rate. Under exposure, emissions gases (CO 2 , N O, CH 4 ) were increased. caused decrease bacteria diversity. Importantly, magnitude impact soil‐based was dependent dose size; however, there is no significant difference type (biodegradable conventional MNPs). Moreover, As uptake plants, but promoted plant Cd accumulation. Using an analytical hierarchy process, we quantified negative as mean value −10.2% (−17.5% −2.57%). Overall, this analysis provides new insights for assessing potential risks ecosystem functions.

Microplastics (MPs) are emerging pollutants that constitutes a very serious environmental nuisance and menace to the globe in last decade. The damages from MPs include ecological imbalance of marine environment, flora, fauna these yet be understood African environment. sustainable development goals 14 15 (SDGs #14 #15) seek address challenges combating sustainability terrestrial lives respectively. Understanding pollution dynamics environment is crucial globally particular Africa soon. Hence, it imperative arrest this challenge as swiftly possible before collapse entire biomes. have been detected several matrices; soil, air, aquatic environments, plants, fishes, animals, humans. Their different source routes: ingestion, inhalation, dermal contact contribute an adverse effect (toxicity) all spheres life. To humans, limits their movement, leads shedding scales, inhibits growth, suppresses immune system, causes inflammation, coagulation, also blood cell toxicity among others, on long-run mortality was noted review. There physical, chemical biological transformation microplastics age, leading toxicity, mobility, great interaction. This has contributed high MP intake by fish other animals. For reason, researchers should delve into simpler cheaper ways analyzing its presence develop remediation strategies curb

Unveiling the mechanism of micro-and-nano plastic phytotoxicity on terrestrial plants: A comprehensive review of omics approaches

Environment International, Год журнала: 2025, Номер 195, С. 109257 - 109257

Опубликована: Янв. 1, 2025

Micro-and-nano plastics (MNPs) are pervasive in terrestrial ecosystems and represent an increasing threat to plant health; however, the mechanisms underlying their phytotoxicity remain inadequately understood. MNPs can infiltrate plants through roots or leaves, causing a range of toxic effects, including inhibiting water nutrient uptake, reducing seed germination rates, impeding photosynthesis, resulting oxidative damage within system. The effects complex influenced by various factors size, shape, functional groups, concentration. Recent advancements omics technologies such as proteomics, metabolomics, transcriptomics, microbiomics, coupled with emerging like 4D omics, phenomics, spatial single-cell offer unprecedented insight into physiological, molecular, cellular responses exposure. This literature review synthesizes current findings regarding MNPs-induced phytotoxicity, emphasizing alterations gene expression, protein synthesis, metabolic pathways, physiological disruptions revealed analyses. We summarize how interact structures, disrupt processes, induce stress, ultimately affecting growth productivity. Furthermore, we have identified critical knowledge gaps proposed future research directions, highlighting necessity for integrative studies elucidate pathways toxicity plants. In conclusion, this underscores potential approaches MNPs-phytotoxicity develop strategies mitigating environmental impact on health.
