In this article, we discuss the phytoremediation of Zn pollution in environment and mechanism plant resistance focusing on mycorrhiza subcellular mechanisms affecting metal binding efflux plants.Phytoremediation is a green low-cost technology that use plants to remove heavy metals (HMs) from soil.As part this, it necessary consider plant's tolerance for example zinc (Zn) together with ability accumulate adapt specific local environment.During process restoring ecosystem contaminations, pH, organic matter, root exudates microbial biomass affect efficiency while considering chemical modification, biosynthesis, assistance gene technology.However, obstacles remain terms modifications may cause either new or disrupt plant-microorganism symbiosis other applications such as genetic engineering change traits function thereby improving absorption.The selection fragments complicated requiring careful considerations due environmental human health side effects.Furthermore, using biochar help reduce costs increase phytoremediation.At same time, there an urgent need combine nanotechnology artificial chelating agents hormones screen microbiome conducive absorption order improve phytoremediation.

Spatiotemporal Response and Phytopotential of Typha domingensis for Management of Aquatic Metal Pollution on the Central African Copperbelt

Ecology and Evolution, Год журнала: 2025, Номер 15(3)

Опубликована: Фев. 28, 2025

ABSTRACT Anthropogenically accelerated metal pollution of lotic systems draining mining landscapes remains a global concern due to its non‐degradability and ecotoxic nature. Nevertheless, the efficacy macrophytes as indicators remediators metal(loid) pollutants in aquatic ecosystems regions is recognised globally. However, mineral‐rich Central African Copperbelt (CACB), there limited research on effectiveness for management. Therefore, this study investigated phytopotential Typha domingensis Pers. (Typhaceae), nature‐based approach managing CACB. A total 252 samples each sediment T. were collected monthly between May 2022 April 2023 from seven streams Kansanshi sub‐catchment CACB analysed evaluate spatiotemporal variability phytoindication phytoremediation potential As, Cu, Pb Zn stream sediments. Metal(loid)s at 71% predominantly accumulated below‐ground biomass with mean concentrations 3–6 mg/kg 9–259 25–36 38–69 Zn. The BAF was above 1 As (0.8–2.6), (10.7–24.3) (1.4–4.3), indicating an accumulator these elements but excluder Cu (BAF < 1). Additionally, TF (1.5–2.0), (1.4–1.5) (1.0–2.0), macrophyte's extraction efficacy. For (TF 1), translocation characterised phytostabiliser. Similar seasonal trends also observed. response phytoindicator phytoremediator contaminants sediments should be considered management CACB's ecosystems.

Abstract Located in Nanhai Town, Songzi City, Hubei Province, Xiaonanhai Lake is the largest natural lake Songzi. It was once severely polluted due to discharge of urban and rural domestic sewage, disorderly development agricultural planting, unregulated aquaculture, poultry farming. However, relevant estimations pollutant content its sediment have not been carried out. This study analyzed spatial patterns heavy metal pollution eutrophication at 36 water sampling sites area, focusing on eight metals: Cd, Cr, Cu, Ni, As, Pb, Hg, Zn. The nutrient status area evaluated using nitrogen‐phosphorus comprehensive index, geo‐accumulation potential ecological risk index. Spatial autocorrelation analysis revealed correlation aggregation levels Lake. results showed that overall trophic state moderate eutrophication, with a gradually decreasing level from north south. Chengnan Wastewater Treatment Plant northern part surface source aquaculture were main nitrogen phosphorus sources. index medium weakened south, consistent thickness bottom mud. load mainly precipitated mud area. significant positive autocorrelation, influence range regional small, heterogeneity relatively high. hotspot (high/high aggregation) ( p < 0.01) while southern cold spot (low/low concentration; 0.05). middle hot concentration) 0.1) 0.1). Therefore, when carrying out environment management Lake, should be prioritized for prevention control dredging.

Heavy metals play a crucial role in the environment due to their toxicity, persistence, and bioaccumulation ability, which can lead severe ecological health risks. This study aimed investigate impact of urbanization agricultural practices on heavy metal content sediments Bug River catchment. To this end, 96 surface sediment samples were collected from various points catchment, including urban, agricultural, forested areas. The for laboratory analysis July 2018, 2019, 2020 Polish part watershed. (Zn, Pb, Cr, Ni, Cu, Fe, Mn, Cd) concentrations determined using atomic absorption spectroscopy (AAS). geoaccumulation index (Igeo), contamination factor (CF), pollution load (PLI) used assess degree contamination. results indicate higher urban sediments, where cadmium reached up 2.5 mg/kg, compared areas, significantly lower. average Igeo value was 0.24 areas 0.15 suggesting predominance anthropogenic influences over natural sources. highest PLI values found reaching maximum 0.33, indicating levels. Statistical revealed that emissions activities influenced presence these sediments. study’s conclusions emphasize effective river water quality management requires continuous monitoring an understanding contribute better interactions between human quality, planning protection remediation strategies. Additionally, provides critical insights into optimizing strategies developing methods, serving local regional policymakers protective actions.
