Potential availability of heavy metals to phytoextraction from contaminated soils induced by exogenous humic substances.
Effective phytoremediation of soils contaminated by heavy metals depends on their availability to plant uptake that, in turn, may be influenced by either the existing soil humus or an exogenous humic matter. We amended an organic and a mineral soil with an exogenous humic acid (HA) in order to enhance the soil organic carbon (SOC) content by 1% and 2%. The treated soils were further enriched wi...

متن کاملMobilization of heavy metals from contaminated paddy soil by EDDS, EDTA, and elemental sulfur.
For enhanced phytoextraction, mobilization of heavy metals (HMs) from the soil solid phase to soil pore water is an important process. A pot incubation experiment mimicking field conditions was conducted to investigate the performance of three soil additives in mobilizing HMs from contaminated paddy soil (Gleyi-Stagnic Anthrosol): the [S, S]-isomer of ethylenediamine disuccinate (EDDS) with app...
متن کاملSoil and Soilless Cultivation Influence on Nutrients and Heavy Metals Availability in Soil and Plant Uptake
Nowadays, most countries especially in arid and dry climate zones had experienced the water scarcity problems. In the agricultural sector, freshwater play a major role to supply water for the plant grows. Thus, the reuse of wastewater as alternative water resources in agricultural is highly recommended. However, wastewater is always contaminated despite after secondary treatment. Along benefici...
متن کاملRemediation of heavy metals contaminated soils by ball milling.
In the present work, the use of ball milling reactors for the remediation of lead contaminated soils was investigated. Lead immobilization was achieved without the use of additional reactants but only through the exploitation of weak transformations induced on the treated soil by mechanical loads taking place during collisions among milling media. The degree of metal immobilization was evaluate...
