Published: Feb. 28, 2024

Microplastics (MPs) contamination presents a significant global environmental challenge, with its potential to influence soil carbon (C) dynamics being crucial aspect for understanding C changes and cycling. This meta-analysis synthesizes data from 110 peer-reviewed publications elucidate the directional, magnitude, driving effects of MPs exposure on globally. We evaluated impacts characteristics (including type, biodegradability, size, concentration), properties (initial pH organic [SOC]), experimental conditions (such as duration plant presence) various components. Key findings included promotion SOC, dissolved C, microbial biomass root following addition soils, while net photosynthetic rate was reduced. No were observed respiration shoot biomass. The study highlights that concentration, along other attributes, critically influences responses. Our results demonstrate both nature environment interact shape cycling, providing comprehensive insights guiding strategies mitigating impact MPs.

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

Environment International, Journal Year: 2025, Volume and Issue: 195, P. 109257 - 109257

Published: Jan. 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.

Understanding how ecosystems respond to ubiquitous microplastic (MP) pollution is crucial for ensuring global food security. Here, we conduct a multiecosystem meta-analysis of 3,286 data points and reveal that MP exposure leads reduction in photosynthesis 7.05 12.12% terrestrial plants, marine algae, freshwater algae. These reductions align with those estimated by constructed machine learning model using current levels, showing reduces the chlorophyll content photoautotrophs 10.96 12.84%. Model estimates based on identified MP-photosynthesis nexus indicate annual losses 4.11 13.52% (109.73 360.87 MT·y −1 ) main crops 0.31 7.24% (147.52 3415.11 MT C·y aquatic net primary productivity induced MPs. Under scenarios efficient plastic mitigation, e.g., ~13% environmental MP-induced are decrease ~30%, avoiding loss 22.15 115.73 crop production 0.32 7.39 seafood production. findings underscore urgency integrating mitigation into hunger sustainability initiatives.

Nanoplastics (NPs) are increasingly perceived as an emerging threat to terrestrial environments, but the adverse impacts of NPs on soil fauna and mechanisms behind these negative outcomes remain elusive. Here, a risk assessment was conducted model organism (earthworm) from tissue cell. Using palladium-doped polystyrene NPs, we quantitatively measured nanoplastic accumulation in earthworm investigated its toxic effects by combining physiological with RNA-Seq transcriptomic analyses. After 42-day exposure, accumulated up 15.9 143.3 mg kg-1 for low (0.3 kg-1) high (3 dose groups, respectively. retention led decrease antioxidant enzyme activity reactive oxygen species (O2- H2O2), which reduced growth rate 21.3 %-50.8 % caused pathological abnormalities.

Decades of nanotoxicology research have generated extensive and diverse data sets. However, is not equal to information. The question how extract critical information buried in vast streams. Here we show that artificial intelligence (AI) molecular simulation play key roles transforming nanotoxicity into information, i.e., constructing the quantitative nanostructure (physicochemical properties)-toxicity relationships, elucidating toxicity-related mechanisms. For AI realize their full impacts this mission, several obstacles must be overcome. These include paucity high-quality nanomaterials (NMs) standardized data, lack model-friendly databases, scarcity specific universal nanodescriptors, inability simulate NMs at realistic spatial temporal scales. This review provides a comprehensive representative, but exhaustive, summary current capability gaps tools required fill these formidable gaps. Specifically, discuss applications simulation, which can address large-scale challenge for research. need powerful new modeling approaches, mechanism analysis, design next-generation are also critically discussed. Finally, provide perspective on future trends challenges.
