“…Rossato et al evaluated the effects of lead on the growth, lead accumulation and physiological responses of Pluchea sagittalis, and concluded that this species is Pb-tolerant, being able to accumulate on average 6730 and 550 µg Pb g −1 dry weight, respectively, in the roots and shoot, a physiological trait which may be exploited for the phytoremediation of contaminated soils and waters [43]. Moreover, Typha domingensis has been studied in the phytoremediation of barium-affected flooded soils [44].…”

Phytoremediation has been considered a sustainable environmental technology for heavy metals decontamination. In this work, we evaluated the metal contents by inductively coupled plasma optical emission spectrometry (ICP-OES) of three plant species collected in a mine in the Brazilian Amazonia area. Based on this analysis, Pluchea sagitallis leaves were selected to prepare metallic ecocatalysts. The leaf ashes and the obtained ecocatalysts were characterized by ICP-OES, X-ray diffraction (XRD), scanning electron microscopy (SEM) and N2-physisorption measurements. Moreover, they were evaluated in the Biginelli and Hantzsch multicomponent reactions, furnishing the corresponding 3,4-dihydropyrimidin-2-(1H)-ones and 1,4-dihydropyridines with good to excellent yields. The best ecocatalyst was easily recovered and recycled in up to six reactions without a significant decrease in its performance.

“…The heterogeneity of the canopy also has a great influence on the water purification capacity of pollutants [7]. According to de Carvalho et al [100], a heterogeneous canopy can improve the absorption effects of the heavy metal barium in flooded soil compared with a homogeneous canopy. In a canopy of heterogeneous density that consists of randomly distributed cylinders, turbulent kinetic energy mainly comes from the shedding of stem-scale vortices, while the generation and dissipation of turbulent kinetic energy are unable to reach a balance [95].…”

On the edges of rivers where the flow velocity is low, aquatic plants flourish, with emergent rigid herbs being the most common. Since the flow structures of vegetated flow are strongly influenced by vegetation distribution patterns, homogeneous and heterogeneous canopies are defined based on the characteristics of vegetation distribution. A review summarizing recent advances in flow structures under the influence of different types of canopy arrangements, including ribbon-like homogeneous canopies, ribbon-like heterogeneous canopies, and patched heterogeneous canopies, is needed. Their flow development process, shear layer properties, coherent structure features, and momentum exchange characteristics are summarized, and a future research agenda for an in-depth understanding of the interactions between vegetation and flow is also highlighted.

Introducing sedum affects root‐soil interface phytoremediation of heavy metals in lei bamboo forest and potential risks from edible bamboo shoots

et al. 2023

Introducing hyperaccumulators in bamboo forests is an efficient method for heavy metals (HMs) pollution control. HMs can be transferred from soil to bamboo and accumulate in edible bamboo shoots. However, how phytoremediation or cropping systems affect root‐soil interface and transference of HMs from soil to bamboo shoots is unknown. In this study, lei bamboo and Sedum plumbizincicola were planted as a monoculture and intercropping system (bamboo/sedum) on contaminated land. Soil properties, rhizosphere bacterial communities, and HMs concentrations in plants and soils were compared among bamboo in monoculture (B), bamboo in intercropping (BI), sedum in intercropping (SI), and sedum in monoculture (S). In BI, the total nitrogen was 10.8% lower, while total organic carbon (TOC) was 12.3% higher than in B; HMs removal amount in BI was higher than in B, especially cadmium. Intercropping increased the HMs concentrations, bioconcentration factor, translocation factor, and hazard quotient of bamboo shoots. Significant differences in bacterial community structures were confirmed by principal coordinate analysis. Gemmatimonadetes, Actinobacteria, Chloroflexi, and Kaistobacter were identified as biomarkers that increased significantly in intercropping, enhancing the diversity of ecological functions in the rhizosphere. Redundancy analysis revealed that rhizosphere bacterial communities were significantly correlated with soil properties, especially TOC and available phosphorus. Intercropping could remarkably alter soil chemical and microbiological properties and facilitate ecosystem restoration by enhancing soil TOC sequestration, activating rhizobacterial community at the root‐soil interface, and finally increasing HMs removal. As the consumption of bamboo shoots grown in contaminated soils may pose health risks, more attention is needed on this issue in phytoremediation studies.
