Effects of microplastics on cadmium accumulation by rice and arbuscular mycorrhizal fungal communities in cadmium-contaminated soil

Nano-Iron Oxide (Fe3O4) Mitigates the Effects of Microplastics on a Ryegrass Soil–Microbe–Plant System

“…This could be explained by the following advantages of Fe nanomaterials: (i) Fe NPs have great potential due to their high adsorption capacity and reactivity and (ii) nano-Fe facilitates rhizosphere microbial changes, particularly in terms of the relative abundances of dominant genera. 16 In the present study, network analysis further confirmed the negative influence of MPs in terms of undermining negative and positive cohesion not only in soil but also in the plant bacterial microbiome, indicating the destabilization of microbial communities. 72 Furthermore, the present results showed that nano-Fe 3 O 4 addition could mitigate the stress caused by MP accumulation, improving ryegrass aboveground bacterial abundance and creating communities dominated by positive associations.…”

“…In the present study, the addition of pure Fe 3 O 4 NPs showed a positive dose effect on the plant microbiome through an increase in bacterial keystone taxa and community associations. This could be explained by the following advantages of Fe nanomaterials: (i) Fe NPs have great potential due to their high adsorption capacity and reactivity and (ii) nano-Fe facilitates rhizosphere microbial changes, particularly in terms of the relative abundances of dominant genera …”

“…In particular, several soil properties that are indicators of soil health, such as the pH, organic carbon, aggregation, aeration, organic matter (OM), water retention capacity, and nutrient (nitrogen (N) and phosphorus (P)) content and availability, are affected. , PE MPs are also known to reduce seed germination by mechanically covering the pore of the seed . Moreover, the bioavailability of heavy metals such as Cd after soil contamination with PE reduces root growth and arbuscular mycorrhizal fungi symbiotic associations with plants . Soil biota are indicators of plant health and nutrient cycling and have a significant impact on soil ecosystem services.…”

“…15 Moreover, the bioavailability of heavy metals such as Cd after soil contamination with PE reduces root growth and arbuscular mycorrhizal fungi symbiotic associations with plants. 16 Soil biota are indicators of plant health and nutrient cycling and have a significant impact on soil ecosystem services. Recent studies have reported that PE MPs have the potential to alter microbial community composition and activities as well as the stability of microfood webs.…”

Ameliorating Effects of Graphene Oxide on Cadmium Accumulation and Eco-Physiological Characteristics in a Greening Hyperaccumulator (Lonicera japonica Thunb.)

“…In addition to the potential impact of GO, excessive heavy metals derived from the metallurgy and mining industry, exhaust emission and sewage irrigation were released into the urban environment and pose a serious threat to the survival of human beings and greening plants [ 47 , 48 , 49 , 50 , 51 ]. Cadmium (Cd), as one of the most toxic heavy metals, has become a global issue of common concern due to its high persistency, strong water solubility and carcinogenicity [ 52 , 53 , 54 ]. The content of Cd in soil exceeds the safety standard of the national soil quality, which will not only result in the inhibition of the eco-physiological characteristics including plant growth, photosynthesis and carbon sequestration and oxygen release functions, but also bring threats to human health induced by food chain transmission [ 55 , 56 , 57 , 58 ].…”
