“…68 Nevertheless, when the colloid concentration exceeds the critical concentration colloidal particles tend to cluster together and are more likely to get trapped in the narrow throat between quartz sand particles due to the increased probability of collision at high concentrations. 69–71 Taken together, the FH–HA colloid-facilitated Sb( v ) transport is attributed to Sb( v ) adsorption on FH–HA surfaces, which was largely affected by colloidal concentration or surface physical-chemistry properties.…”

“…As mentioned above, MPs with different surface charge groups affect the kinetics of essential elements uptake and adsorption by roots. For example, functional groups such as -OH, -COOH, -SO 3 H, or -NH 2 group might reduce elemental adsorption by blocking the extracellular adsorption pathway ( Li et al., 2020a ), by directly repelling elements with the same surface charges ( Fu et al., 2022 ), or by the attraction and hetero-aggregation of opposite charge to each other, thereby reducing the element adsorption by roots ( Li et al., 2021a ; Xia et al., 2021 ; Song et al., 2023 ).…”

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 to MP stress, thereby affecting overall plant growth and development. This review article has critically analyzed the effects of MP stress in plants. We found that MP stress-induced reduction in plant physical growth is accompanied by two complementary effects: (i) blockage of pores in seed coat or roots to alter water and nutrient uptake, and (ii) induction of drought due to increased soil cracking effects of MPs. Nonetheless, the reduction in physiological growth under MP stress is accompanied by four complementary effects: (i) excessive production of ROS, (ii) alteration in leaf and root ionome, (iii) impaired hormonal regulation, and (iv) decline in chlorophyll and photosynthesis. Considering that, we suggested that targeting the redox regulatory mechanisms could be beneficial in improving tolerance to MPs in plants; however, antioxidant activities are highly dependent on plant species, plant tissue, MP type, and MP dose. MP stress also indirectly reduces plant growth by altering soil productivity. However, MP-induced negative effects vary due to the presence of different surface functional groups and particle sizes. In the end, we suggested the utilization of agronomic approaches, including the application of growth regulators, biochar, and replacing plastic mulch with crop residues, crop diversification, and biological degradation, to ameliorate the effects of MP stress in plants. The efficiency of these methods is also MP-type-specific and dose-dependent.

“…GO (42-62% wt carbon, 24-36% wt oxygen) can be prepared from graphite in the laboratory using the Hummers and Offemans method ( Marcano et al., 2010 ; Yu et al., 2016 ), and further modified by reduction of C=O groups or their derivatization e.g., with metal atoms (Zn, Cu, Ag), which enables environmental adsorptive detoxication from metalloids ( Zhang et al., 2020 ; Sengupta et al., 2022 ). GO is quite mobile in soil ( Sangani et al., 2019 ; Xia et al., 2021 ); however, its leaching can be reduced by aggregation mediated by Ca 2+ in concentration ≥ 0.5 mM ( Qi et al., 2014 ). Amendment of GO to soil alters its hygroscopic and adsorptive capabilities and water content, and reduces the impact of drought stress ( Zhao et al., 2020 ; Zhao et al., 2022 ); as a carrier, it increases the uptake of mineral micronutrients to plants via controlled release ( Kabiri et al., 2017 ; Li et al., 2019 ; Carneiro et al., 2022 ; Mohammadi Alagoz et al., 2022 ).…”

The impact of graphene oxide (GO) nanocarbon on soil properties is mixed, with both negative and positive effects. Although it decreases the viability of some microbes, there are few studies on how its single amendment to soil or in combination with nanosized sulfur benefits soil microorganisms and nutrient transformation. Therefore, an eight-week pot experiment was carried out under controlled conditions (growth chamber with artificial light) in soil seeded with lettuce (Lactuca sativa) and amended with GO or nano-sulfur on their own or their several combinations. The following variants were tested: (I) Control, (II) GO, (III) Low nano-S + GO, (IV) High nano-S + GO, (V) Low nano-S, (VI) High nano-S. Results revealed no significant differences in soil pH, dry plant aboveground, and root biomass among all five amended variants and the control group. The greatest positive effect on soil respiration was observed when GO was used alone, and this effect remained significant even when it was combined with high nano-S. Low nano-S plus a GO dose negatively affected some of the soil respiration types: NAG_SIR, Tre_SIR, Ala_SIR, and Arg_SIR. Single GO application was found to enhance arylsulfatase activity, while the combination of high nano-S and GO not only enhanced arylsulfatase but also urease and phosphatase activity in the soil. The elemental nano-S probably counteracted the GO-mediated effect on organic carbon oxidation. We partially proved the hypothesis that GO-enhanced nano-S oxidation increases phosphatase activity.
