Extraction of heavy metals from copper tailings by ryegrass (Lolium perenne L.) with the assistance of degradable chelating agents

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: April 1, 2024

Abstract Heavy metal contamination is an urgent ecological governance problem in mining areas. In order to seek for a green and environmentally friendly reagent with better plant restoration effect solve the of low efficiency heavy pollution soil. this study, we evaluated effects three biodegradable chelating agents, namely citric acid (CA), fulvic (FA) polyaspartic (PASP), on physicochemical properties copper tailings, growth ryegrass ( Lolium perenne L.) accumulation therein. The results showed that agent application improved increased biomass enriched more Cu Cd tailings. control group, main existing forms were oxidizable state, followed by residual, weak soluble reducible states. After CA, FA or PASP application, converted from residual states states, whose bioavailability tailings thus enhanced. Besides, incorporation extraction efficiencies as manifested root stem contents 30.29–103.42%, 11.43–74.29%, 2.98–110.98% 11.11–111.11%, respectively, comparison group. presence multiple metals, selectivity regarding metals PCA analysis revealed CA-4 PASP-7 treatment had great remediation potentials against increases 90.98% 74.29% compared CK

Rhizosphere microbiome of plants used in phytoremediation of mine tailing dams

International Journal of Phytoremediation, Journal Year: 2024, Volume and Issue: 26(8), P. 1212 - 1220

Published: Jan. 12, 2024

Rhizospheric microbial communities improve the effectiveness of hyperaccumulators in phytoremediation heavy metals. However, limited access to tailing dams and inadequate assessment plants' potential limit characterization native accumulators, hindering local remediation efforts. This study evaluates metal sequestration potentials Pennisetum purpureum, Leucaena leucocephala, Pteris vittata their associated rhizospheric at Marlu Pompora Ghana. The results indicate shoot hyperaccumulation Cd (334.5 ± 6.3 mg/kg) Fe (10,647.0 12.6 P. purpureum L. respectively.

The Addition of Degradable Activators Enhances Sedum alfredii Phytoremediation Efficiency in Cd-Contaminated Soils

Sustainability, Journal Year: 2025, Volume and Issue: 17(7), P. 3207 - 3207

Published: April 3, 2025

Soil cadmium (Cd) pollution is a critical environmental issue that requires urgent remediation. Sedum alfredii Hance, known for its high biomass, strong stress tolerance, and suitability harvesting, serves as an excellent hyperaccumulator. This study used field experiments to investigate the enhancement of Cd phytoremediation in soil using three activators: citric acid (CA), malic (MA), polyaspartic (PASP). The results showed biomass was increased by 8.95–28.37% addition these activators, significantly boosting accumulation efficiency, with average removal rate increase 12%. Among all CA exhibited most substantial effect, enrichment coefficients 36.26% 11.56% aboveground parts roots alfredii, respectively, 21.15% rate. Although PASP had less pronounced effect on uptake, decreases 15.25% 35.34% roots, it impacted speciation activation 20%.
