“…Most recent studies demonstrate growth inhibition, while only a handful of species exhibit a positive growth response, particularly in the presence of PE (Figure 1). These additions include barley [79], cucumber, tomato, and lettuce plants [50], adding to previously identified species such as Allium fistulosum, T. aestivum, L. sativum, Calamagrostis epigejos, and Hieracium pilosella (reviewed in [20]). However, the aggregated results indicate that plastics, including PS, PE, PVC, and biodegradable variants, have predominantly detrimental effects on plant growth, particularly in relation to root and shoot development.…”

“…While plastic waste is known to harm marine life [ 47 ], scientists have only recently begun to realize the impact of MP pollution on terrestrial ecosystems [ 48 ] and its effect on plants [ 49 ]. The potential impacts of MPs and NPs on plants and the issue of food safety concerns for crops have been discussed recently [ 49 ], and subsequent studies have confirmed that NPs can be absorbed by plant roots and translocated to the aboveground aerial tissues [ 50 ]. These studies have demonstrated that MPs and NPs can induce physiological changes in plants, such as a reduction in growth, photosynthesis, and antioxidant activity, as well as alterations in gene expression and root exudate profiles [ 49 , 51 ].…”

“…An experiment with lentil ( Lens culinaris Medik) plants demonstrated that their germination was inhibited by PE [ 78 ]. Moreover, a study found that PE significantly increased the shoot growth of lettuce, barley ( Hordeum vulgare L.), cucumber, and tomato ( Solanum lycopersicum L.) plants [ 50 , 79 ]. Conversely, according to another study, root development was reduced by PE in cucumber and tomato plants [ 79 ].…”

Plastics have inundated the world, with microplastics (MPs) being small particles, less than 5 mm in size, originating from various sources. They pervade ecosystems such as freshwater and marine environments, soils, and the atmosphere. MPs, due to their small size and strong adsorption capacity, pose a threat to plants by inhibiting seed germination, root elongation, and nutrient absorption. The accumulation of MPs induces oxidative stress, cytotoxicity, and genotoxicity in plants, which also impacts plant development, mineral nutrition, photosynthesis, toxic accumulation, and metabolite production in plant tissues. Furthermore, roots can absorb nanoplastics (NPs), which are then distributed to stems, leaves, and fruits. As MPs and NPs harm organisms and ecosystems, they raise concerns about physical damage and toxic effects on animals, and the potential impact on human health via food webs. Understanding the environmental fate and effects of MPs is essential, along with strategies to reduce their release and mitigate consequences. However, a full understanding of the effects of different plastics, whether traditional or biodegradable, on plant development is yet to be achieved. This review offers an up-to-date overview of the latest known effects of plastics on plants.

“…Microplastics (MPs) are defined as small plastic fragments of <5 mm diameter. Although research on soil MPs commenced relatively late compared to that in aquatic environments, recently, a large number of studies have focused on the effects of MPs on soil physical and chemical properties, enzyme activities, and microbial communities (Li et al, 2021; Liu, Li, et al, 2023; Liu, Liang, et al, 2023; Qiu et al, 2022; Wang, Wang, et al, 2022).…”

Microplastics (MPs) enter the global soil ecosystem in significant quantities, and in agricultural lands, interact with soil amendments (e.g, fertilisers, pesticides, biochar), pollutants (e.g., heavy metals and acid rain) and soil fauna (e.g., earthworms and microbial biomass) which impacts carbon (C) and nitrogen (N) cycling in soil in ways that are largely unexplored. Here, we analyzed the difference in the responses of soil C and N contents, greenhouse gas emissions and soil enzyme activities in experiments where MPs alone or MPs in combination with other soil amendments or soil fauna had been explored, by conducting a global meta‐analysis of 2543 observational data extracted from 84 published studies. The results show that MPs alone are associated with significantly increased soil C storage and altered soil N pool composition, increased soil carbon dioxide (CO2) and nitrous oxide (N2O) emissions, reduced soil ammonia (NH3) emissions, increased activity of one of the five major enzymes related to C cycle, and increased activity of three of the four major enzymes related to N cycling in soil. Experiments that explored the combined effects of MPs combined with fertilisers on soil C and N contents and enzyme activities indicated greater effects than MPs alone. However, the effects of MPs combined with soil fauna, heavy metals, acid rain, glyphosate, and carbon nanotubes on soil C and N cycling differed from findings of studies that considered the effects of MPs alone. The results of this meta‐analysis rovide a theoretical basis for further study of the effects of MPs on C and N cycling in fertilized agricultural soil, compound‐contaminated soil and acidified soil. We also show that, despite the global importance of MPs in soil, the number of studies of their effects on soil C and N cycling are relatively few, and further research on the mechanisms of interactions of MPs with multiple soil amendments in soil systems is urgently needed.This article is protected by copyright.

Microplastics affect ecosystem multifunctionality: Increasing evidence from soil enzyme activities

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