This study aimed to identify suitable plants for remediating metal pollution in copper tailing soil and supporting ecological reclamation Dongchuan, Yunnan, focusing on three major mining regions: Tangdan, Yinmin, Lanniping. The Nemerow comprehensive index was employed evaluate the contamination levels, enrichment transfer capacities of dominant Cd, Cu, Pb, Zn were analyzed remediation candidates. findings revealed severe soil, with Cu as primary pollutant, a rate 77.778%. A total 96 plant species from 42 families 87 genera recorded, including 29 across 17 26 genera, herbs comprising 62.068% types. Among tested plants, Leucaena leucocephala, Rumex acetosa, Festuca rubra, Salix balfouriana exhibited significantly higher capacities, rendering them restoration. highest membership function score 5.298 identified preferred restoration Dongchuan area.

The accumulation of heavy metals in the soil not only causes serious damage to ecosystem, but also threatens human health through food chain. Exopolysaccharides have functions adsorbing and chelating reducing their bioavailability soil. In our study, exopolysaccharide-producing bacteria with a high efficiency cadmium (Cd) lead (Pb) were screened from metal-contaminated farmland. Through pot experiments, influence functional strains on size distribution, metal content, bacterial community structure aggregates lettuce was studied using high-throughput sequencing technology. results show that 11 secreting exopolysaccharides initially Among them, strain Z23 had removal rate 88.6% for Cd 93.2% Pb. at which removed by Z39 92.3%, Pb 94.4%.

This investigation delves into the impact of shale gas extraction and subsequent land reclamation on soil characteristics plant carbon sequestration within Fuling District, specifically focusing Jiaoshi Town. Through meticulous sampling analysis, study evaluates modifications in soil's physical chemical properties pre- post-reclamation, encompassing pH, bulk density, moisture content, nitrogen, phosphorus levels, heavy metal concentrations. Concurrently, potential several reintroduced local species is assessed. Findings indicate a slight alkaline shift pH with notable improvements structure, reflected by decreased density enhanced fostering better conditions for growth. An increase nitrogen content post-reclamation suggests fertility, pivotal agricultural productivity. research contributes to understanding environmental restoration effectiveness following industrial disturbances, offering insights optimizing practices ecological balance sustainable management gas-affected regions.

Heavy metals can adversely affect physicochemical properties soil plant health. Prolonged exposure heavy in humans lead both carcinogenic non-carcinogenic effects. present research intended determine dispersion condition toxic cropland assess attendant environmental health dangers Wonosobo Regency. This study used a sample survey encompassing 312 sampling sites. completed analyses comprise geographical analysis, index geo-accumulation (IG), contamination (CI), Nemerow comprehensive (NCCI), risk analysis. findings reveal that cadmium material primary contributor from Regency, as shown by IG CI hazards assessments suggest considerable pollution levels. Kids are more prone illnesses than adults due their daily intake amount, so it necessary pay attention sources children minimize metals.

Constructed wetlands (CWs) have emerged as effective biotechnological solutions for wastewater treatment in recent decades. While plants are recognized components of these systems, their specific role nutrient and heavy metal (HM) uptake warrants further investigation. This study assesses the efficacy a vertical flow constructed wetland (VFCW) unit planted with Phragmites australis treating HM-laden wastewater. Through standard methods, samples from inlet outlet were analyzed HMs (Cd, Zn, Pb, Cu), alongside plant sediment samples. Planted CWs demonstrated remarkable removal efficiencies: 89.34% Cd, 76.27% 68.14% Cu, 66.42% surpassing unplanted systems (18.27% to 33.16% removal). Notably, P. exhibited strategic pollutant absorption, highest HM concentrations below-ground. Though above-ground accumulation was relatively minor, it exceeded soil concentrations. Analysis factors confirmed roots rhizomes primary bio-accumulators, transfer factor values (Cd > Pb Zn Cu) indicating efficient uptake. These findings underscore pivotal enhancing within VFCW emphasizing importance plant-based strategies remediation. Recommendations include exploration plant-assisted methods optimize CWs.
