Microplastics affect ecosystem multifunctionality: Increasing evidence from soil enzyme activities

Land Degradation and Development, Journal Year: 2024, Volume and Issue: 35(15), P. 4379 - 4405

Published: July 22, 2024

Abstract Microplastics (MPs) as emerging contaminants have a global occurrence, including both terrestrial and marine ecosystems. Soil enzymes contribute to maintaining ecosystem multifunctionality, for example, nutrient cycling, organic material decomposition, carbon climate regulation. Our present review highlights the impacts of MPs on soil enzyme activities, influencing factors, underlying mechanisms. Increasing findings confirm that can change activities range involved in biogeochemical cycling C N. However, current results are highly controversial. The effects vary from significant nonsignificant dependent polymer type, biodegradability, dosage, size, shape, aging degree MPs, exposure conditions. Compared traditional biodegradable generally show more pronounced effects. via different pathways. On one hand, directly structure, leading alterations activity. other create unique habitats, provide sources specific functional microbes producing enzymes, release plastic additives pollutants disturbing production these enzymes. Furthermore, alter physicochemical biological properties, availability substrates, plants fauna, regulating their functions. In conclusion, regulate pose profound impact multifunctionality.

Published: March 1, 2025

Micro/Nano-plastics (M/NPs) have emerged as a globally concerning pollutant. However, research on the phytotoxicity of M/NPs plant secondary metabolism and underlying molecular mechanisms is still limited. Pepper, widely cultivated vegetable, rich in flavonoids, which are class important metabolites found throughout kingdom with multiple biological functions. In this study, we conducted detailed assessment physiological toxicity Polyethylene Terephthalate microplastics (PET-MPs) growth pepper seedlings. Results showed that PET-MPs significantly inhibited growth, particularly root development. Moreover, exposure resulted burst ROS, causing oxidative damage. KEGG pathways analysis illustrated altered flavonoid biosynthesis phenylpropanoid at both metabolome transcriptome levels. Weighted gene correlation network (WGCNA) identified ten structural genes nine transcription factor play pivotal roles regulating biosynthesis. summary, study elucidates alterations composition, along regulatory governing under pepper. These findings enhance our comprehension MPs pollution provide valuable insights for development sustainable agro-ecosystems food security future.

Submerged plants and related disturbances can affect both the phosphorus (P) release microbial communities in sediments. In this study, a sediment resuspension system was constructed, P variability characteristics influenced by Vallisneria natans (V. natans) response mechanism of community were studied. The results indicated that total (TP) content increased from 678.875 to 1019.133 mg/kg 1126.017 1280.679 sediments suspended solids (SSs) during process, respectively. Organic (OP) 127.344 302.448 SSs after disturbance, leaves V. had higher Chao values while Shannon decreased disturbance compared control SSs. Proteobacteria highest abundance with value 51.1% SSs, rhizomes could reach 73.2% on average. Chloroflexi, Acidobacteria, Firmicutes also main phyla system.
