Microplastic contamination poses a significant threat to agroecosystem functioning, provoking move away from the use of conventional oil-based plastics in agriculture, biodegradable alternatives that may be degraded over shorter timescale. The impact these bioplastics on plant and soil health, however, has received relatively little attention. Here, we investigated effect loading (0.01%, 0.1%, 1% 10%) biobased microplastic poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) (Zea mays L.) health function. We showed PHBV caused dose-dependent reduction growth foliar nitrogen (N) content while untargeted metabolite analysis revealed shifts metabolic These results were also reflected soil, where led reduced availability both ammonium nitrate. Soil 14C-isotope tracing 16S metabarcoding suppressed microbial activity, bacterial diversity shifted community structure, inducing major shift pathways, thus functioning. Overall, our data suggests bioplastic is not environmentally benign levels as low 0.01% (0.01 mg kg-1) can induce short-term changes with potential implications for long term health.

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

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

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.

Although our understanding of the effects microplastics on dynamics soil organic matter (SOM) has considerably advanced in recent years, fundamental mechanisms remain unclear. In this study, we examine polyethylene and poly(lactic acid) SOM processes via mineralization incubation. Accordingly, evaluated changes carbon dioxide (CO2) methane (CH4) production. An O2 planar optical sensor was used to detect temporal behavior dissolved during incubation determine microscale oxygen heterogeneity caused by microplastics. Additionally, (DOM) were using a combination spectroscopic approaches ultrahigh-resolution mass spectrometry. Microplastics increased cumulative CO2 emissions 160–613%, whereas CH4 dropped 45–503%, which may be attributed oxygenated porous habitats surrounding Conventional biodegradable changed quantities carbon. microplastic treatments, DOM with more polar groups detected, suggesting higher level electron transport. addition, there positive correlation between concentration, electron-donating ability, emission. These findings suggest that facilitate modifying microenvironments, transport capability. study provides new insights into impact dynamics.
