“…Moreover, accounting for species-specific responses could avoid potential alterations to plant biodiversity, due to plant-specific anatomical, physiological, and biological traits. , However, supplementary analysis revealed that crop species, specifically herbaceous plants (71%) and gramineous plants (29%), are strongly represented in current studies (Figure S5a). These studies on crop plants have significant implications for food safety and human health due to accumulation of nanoplastics in edible portions of plants.…”

Threats to Terrestrial Plants from Emerging Nanoplastics

Nanoplastics are ubiquitous in ecosystems and impact planetary health. However, our current understanding on the impacts of nanoplastics upon terrestrial plants is fragmented. The lack of systematic approaches to evaluating these impacts limits our ability to generalize from existing studies and perpetuates regulatory barriers. Here, we undertook a meta-analysis to quantify the overall strength of nanoplastic impacts upon terrestrial plants and developed a machine learning approach to predict adverse impacts and identify contributing features. We show that adverse impacts are primarily associated with toxicity metrics, followed by plant species, nanoplastic mass concentration and size, and exposure time and medium. These results highlight that the threats of nanoplastics depend on a diversity of reactions across molecular to ecosystem scales. These reactions are rooted in both the spatial and functional complexities of nanoplastics and, as such, are specific to both the plastic characteristics and environmental conditions. These findings demonstrate the utility of interrogating the diversity of toxicity data in the literature to update both risk assessments and evidence-based policy actions.

“…There was no significant difference in the amount of total biomass between the microplastic treatments of experiment and the control. For comparison, Gong et al (2021) found the zero effect of PS contamination on total biomass of radish and wheat, a slight effect on maize and a significant effect on lettuce at early seedling growth.…”

“…The effects of microplastics on biomass in terrestrial ecosystems have been studied in several species, including wheat (Gong et al, 2021;Qi et al, 2018), onion (Machado et al, 2019), common bean (Meng et al, 2021), pumpkin (Colzi et al, 2022;Gonnelli, 2022), Italian lettuce, radish and corn (Gong et al, 2021). Colzi et al (2022) indicated that the higher the microplastics concentration, the greater the negative effect on chlorophyll content and photosynthetic efficiency.…”

Microplastics (particles of plastics <5 mm) affect the physical, biological and hydrological properties of agricultural soil, as well as crop growth. We investigated the effect of the addition of three microplastics (high-density polyethylene (HDPE), polyvinyl chloride (PVC), and polystyrene (PS)) at a concentration of 5% (w/w) to a silty loam soil on selected soil properties and growth of radish (Raphanus sativus L. var. sativus). Changes in the soil properties and radish growth in three microplastic treatments were compared with the control. Soil properties (bulk density, hydraulic conductivity, sorptivity, water repellency) were estimated for each treatment at the beginning and at the end of the radish growing period (GP). The bulk density was significantly lower in the HDPE and PVC treatments compared to the control within the measurement at the beginning of the GP and in all microplastic treatments compared to the control at the end of the GP. The values of hydraulic conductivity and water sorptivity did not show significant differences between any treatments within the measurement at the beginning of GP, but they were significantly higher in the HDPE treatment compared to the control at the end of the GP. The growth of radish was characterized by the plant biomass and effective quantum yield of Photosystem II (Y (II)). We did not find a statistically significant difference in the total biomass of radish between any of the experimental treatments, maybe due to used concentration of microplastics. The mean value of Y (II) was significantly higher in all microplastic treatments compared to control only within the last measurement at the end of the GP. A statistically significant change of Y(II) in all microplastic treatments may indicate functional shift in soil properties; however, the measured values of the soil characteristics have not shown the significant changes (except for the bulk density values in all microplastic treatments and hydraulic conductivity together with sorptivity in HDPE treatment within the measurement at the end of GP).

“…MPs with a small particle size are more toxic to plants (Jiang et al, 2019). On the other hand, NPs and MPs at submicrometer or micron levels may enter the plant body and cause harm by changing the state of cell membranes and intracellular molecules and causing oxidative stress (Giorgetti et al, 2020;Li et al, 2020;Gong et al, 2021;Yin et al, 2021;Liu et al, 2022). Both nano-and micro-sized MPs may accumulate in the interspace tissues of plant roots and then transfer to the leaves, stems, flowers, and fruits Liu et al, 2022).…”

“…Both nano-and micro-sized MPs may accumulate in the interspace tissues of plant roots and then transfer to the leaves, stems, flowers, and fruits Liu et al, 2022). In addition, MPs can also affect the absorption of other substances, such as Fe, Mn, Cu, and Zn, by plants (Lian et al, 2020a), and the phytotoxicity of MPs is clearly plant species-dependent (Gong et al, 2021).…”

Microplastics are <5 mm in size, made up of diverse chemical components, and come from multiple sources. Due to extensive use and unreasonable disposal of plastics, microplastics have become a global environmental issue and have aroused widespread concern about their potential ecological risks. This review introduces the sources, distribution and migration of microplastics in agricultural soil ecosystems. The effects of microplastics on soil physicochemical properties and nutrient cycling are also discussed. Microplastics can alter a series of key soil biogeochemical processes by changing their characteristics, resulting in multiple effects on the activities and functions of soil microorganisms. The effects of microplastics on soil animals and plants, the combined effects of microplastics and coexisting pollutants (organic pollutants and heavy metals), and their potential risks to human health are also discussed. Finally, prevention and control strategies of microplastic pollution in agricultural soil ecosystems are put forward, and knowledge gaps and future research suggestions about microplastic pollution are given. This review improves the understanding of environmental behavior of microplastics in agricultural soil ecosystems, and provides a theoretical reference for a better assessment of the ecological and environmental risks of microplastics.
