AbstractMicroplastics (MPs) are emerging contaminants that adversely affect environmental health. In this review, we discuss the uptake of MPs by plants via endocytosis and crack-entry pathways in roots stomata leaves; translocation xylem phloem; toxicity to diverse plant species through oxidative stress, inhibition photosynthesis, cytotoxicity, genotoxicity. It's difficult assess health risks because they directly cause also change soil properties bioavailability coexisting pollutants, such as plastic additives, rhizosphere, bioaccumulate along food chain. Moreover, compared behavior phytotoxicity effects laboratory hydroponic studies, various shapes, sizes, types likely different on complex natural environments. This review proposes potential phytoremediation strategies, including phytoextraction, immobilization, rhizoremediation, for MP pollutants provides guidelines bioremediation MP-contaminated environments enhance sustainability. pollution, selection disposal used optimization functional microbes rhizosphere remain challenging. Future studies should address knowledge gaps (i) methods determining environmentally-relevant concentrations MPs, (ii) assessment ecological human environment, (iii) development effective strategies pollution.Keywords: Emerging contaminantenvironmental healthplastic additiverhizosphere effectsoil propertyuptakeHandling Editors: Chang-Ping Yu Lena Q.

A mesocosm experiment was set-up to investigate the effects of low-density polyethylene (LDPE) fragments deriving from plastic film on soil ecology, rhizosphere and plant (Salvia officinalis L.) fitness. The internal transcribed spacer (ITS) 16S metagenomic analysis adopted evaluate taxonomic functional shifts both under influence microplastics (MPs).

Ecotoxicological effects of polystyrene nanoplastics on common carp: Insights into blood parameters, DNA damage, and gene expression

Journal of Applied Toxicology, Год журнала: 2024, Номер 44(9), С. 1416 - 1425

Plastics are ubiquitous in modern society due to their cost-effectiveness, lightweight nature, and versatility. However, extensive use inadequate recycling have led a significant environmental challenge, with plastic waste accumulating rapidly causing ecological health problems, especially aquatic environments. Nanoplastics, particles ranging from 1 100 nm, emerged as particularly concerning subset ability easily penetrate biological barriers accumulate tissues. In this study, we investigated the toxicity of carboxylate-modified polystyrene nanoplastics (PS-NPs) on common carp (Cyprinus carpio), species often used ecotoxicology research its pollutants. The PS-NPs were characterized, effects DNA damage gene expression related oxidative stress immunity examined. diameter 20-30 nm found possess spherical shape negatively charged surfaces. Exposure blood brain cells carp, higher concentrations resulting more severe damage. Additionally, PS-NP exposure influenced genes antioxidative defense response liver. Specifically, encoding superoxide dismutase (SOD), catalase (CAT), heat shock protein 70 (Hsp70) showed upregulation, while glutathione peroxidase (GPx) S-transferase (GST) exhibited downregulation at concentrations. Furthermore, immune-related interleukin-1ß (IL-1ß), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α) displayed dose-dependent liver tissue. These findings suggest that induces stress, disrupts immune responses, causes carp. results highlight need for further impacts underscore importance proper management practices mitigate pollution.

Effects of Microplastics and its Combination with Cadmium on Pinus Massoniana Are Dependent on the Type of Microplastics

Опубликована: Янв. 1, 2025

The widespread occurrence of microplastics (MPs) in various environments globally often coincides with the presence toxic heavy metals, leading to co-contamination toxicity plants. However, differences between conventional and degradable MPs their effects on tree responses metals remain inadequately understood. Here, we conducted a pot experiment investigate different types (i.e., polyethylene (PE) polylactic acid (PLA)), combination cadmium (Cd), growth, physiological biochemical traits Pinus massoniana seedlings. results shows that 10% PE-only was more harmful growth physiology P. compared PLA-only. Furthermore, 1% + Cd did not significantly impact growth. Nevertheless, under PLA, higher than PLA Cd. Under treatments Cd, enhanced absorption by roots, while other inhibited uptake. Overall, its were dependent type MPs, providing significant implications for seedling cultivation forest management context increasing human activities.
