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 کاملEnhanced phytoextraction of Pb and other metals from artificially contaminated soils through the combined application of EDTA and EDDS.
Chemically enhanced phytoextraction is achieved by the application of chelates to soils. Using pot experiments, the effect of the combined application of EDTA and EDDS on the uptake of Cu, Pb, Zn and Cd by Zea mays L. was studied. Among the tested application ratios of 1:1, 1:2, and 2:1 (EDTA/EDDS), 2:1 of EDTA:EDDS was the most efficient ratio for increasing the concentrations of Cu, Pb, Zn an...
متن کاملPhytoextraction of Cd-Contaminated Soils: Current Status and Future Challenges
Cadmium (Cd) is one of the most toxic and widely distributed pollutants in the environment. Cadmium contamination of soils has posed a serious threat to safe food production in many parts of the world. The authors present a comprehensive review of present status of phytoextraction technology for cleaning up Cd-contaminated soils, based primarily on the data resulting from both laboratory and fi...
متن کاملNovel Approaches to Bioindication of Heavy Metals in Soils Contaminated by Oil Shale Wastes
The major sources of heavy metal pollution in Estonia are oil shale industry and oil shale combustion. There is an utmost need to monitorsoil pollution with heavy metals in this region. Earthworms are good accumulators of heavy metals and can be used as bioindicators. Endogeic species Aporrectodea caliginosa and Aporrectodea rosea as well as anecic species Lumbricus terrestris are good bioindic...
