Cadmium (Cd) is one of the most harmful heavy metals in environment, negatively impacting plant growth and development. However, phytoremediation which an environmentally friendly cost-effective technique can be used to treat Cd contaminated environments. It effectively removes from polluted soil water through processes, such as phytoextraction, phytostabilization, phytostimulation, phytofiltration, phytotransformation. Numerous research has shown evidences that biological, physical, chemical, agronomic, genetic methods are being utilized improve phytoremediation. A special group plants known hyperaccumulator further enhance removal, turning areas into productive land. These accumulate root cell vacuoles aerial parts. Despite morphological variations, different species remediate at rates using either or multiple mechanisms. To effectiveness phytoremediation, it essential thoroughly understand mechanisms control accumulation persistence plants, including absorption, translocation, elimination processes. what missing understanding depth idea on how limitations overcome. The addressed various strategies, natural chemical amendments, engineering, microbial stimulation, broadly categorized amelioration capacity enhancement approaches. This review presents a concise overview latest employed this process. Moreover, also underscores creditability pollution offers promising approach for eliminating sites restoring their productivity. Additionally, we recommend directing future toward enhancing biochemical capabilities remediation purposes, elucidating molecular underlying damage caused by fundamental principles regulating enrichment plants.

The simultaneous presence of microplastics (MPs) and heavy metals in soil may result heightened toxicity, causing more significant adverse effects on plant growth. Plant growth-promoting rhizobacteria (PGPR) have demonstrated capacities alleviating the toxic stress caused by combined pollution other contaminants. However, research impacts processes PGPR induced from MPs is still insufficient. This study involved a pot experiment to evaluate ability mitigate polypropylene microplastic (PP MPs) particles different sizes (6.5 μm 830 μm) metal cadmium (Cd) bioenergy hybrid Pennisetum. Moreover, metagenomic analysis was used examine rhizospheric microbial community function. cocontamination PP Cd affected growth Pennisetum differently depending size particles, with aboveground underground lengths 6.5 + experimental group being smaller than those group. PGPRs ( Bacillus sp. Y-35, Y-62, Y-S, Enterobacter Y-V) successfully alleviated Cd, resulting increases 8.24 42.21% height dry weight, respectively. studies indicated that along inoculation, altered composition bacterial community, leading changes diversity indices dominant groups such as Pseudomonadota, Actinomycetota, Acidobacteriota. functional revealed main glucose metabolism, energy signal transduction, nucleotide metabolism. particle significantly functions pentose phosphate pathway, benzoate degradation, amide biosynthesis. provides essential data scientific evidence ecotoxicological contamination metals, well insights into potential bioremediation methods.

Microplastics and heavy metal contamination frequently co-occur in stormwater filtration systems, where their interactions may potentially compromise nitrogen removal. Current research on microplastics Cd predominantly focuses soils constructed wetlands, with limited attention given to systems. In this study, the single synergistic effects of aged polyethylene (PE) cadmium (Cd) infiltration systems were investigated from perspectives removal, microbial community structures, predicted functional genes cycling. Results showed that PE demonstrated stronger inhibition NO3−–N removal than Cd. Low-level (PE content: 0.1% w/w) Cd-contaminated inhibitory effect high-level 5% w/w). The mean efficiency under combined Cd50 (Cd concentration: 50 μg/L) PE5 during sixth rainstorm event was 1.04 34.68 times other scenarios. Metagenomic analysis identified keystone genera (Saccharimonadales, Enterobacter, Aeromonas, etc.), critical transformation pathways (nitrate reduction ammonium, denitrification, fixation, nitrification) govern system performance. most pronounced nitrification/denitrification enzymes beyond nitrite oxidase nitrate reductase. These mechanistic findings advance our understanding co-contaminant
