Selenium Speciation in Salicornia bigelovii: Plant-Mediated Reduction of Selenate for the Remediation of Selenium Contaminated Soil
Selenium contamination of soil in the San Joaquin Valley, California poses a threat to wildlife and to agricultural productivity. Traditional phytoremediation methods use the process of phytoextraction to remove selenium from soil by sequestering selenium in plant tissues, potentially allowing the re-release of selenium to the soil if the plants are not harvested after senescence. The volatiliz...
متن کاملTransformation of heavy metal fractions on soil urease and nitrate reductase activities in copper and selenium co-contaminated soil.
This study aims to explore the effects of the distribution, transformation and bioavailability of different fractions of copper (Cu) and selenium (Se) in co-contaminated soils on soil enzymes, providing references for the phytoremediation of contaminated areas and agriculture environmental protection. Pot experiments and laboratory analysis were used to investigate the transformation and bioava...
متن کاملDetermination and fractionation of sulphur in a contaminated dredged sediment.
Conversion of sulphur compounds in reduced, contaminated sediments that are brought in upland conditions may largely affect the potential mobility of heavy metal contaminants. We applied selected methods for the determination of total sulphur and sulphur fractions in a contaminated sediment in the reduced state and after gradual drying and oxidation during 1 month. Dry ashing, followed by ion c...
متن کاملSoil migration, plant uptake and volatilisation of radio-selenium from a contaminated water table.
The properties of (79)Se make it of likely potential importance in safety studies for geological disposal of radioactive wastes. Despite a substantial literature on toxic and nutritional aspects of selenium in the environment little consideration has been given to the behaviour of radioactive selenium and its potential transfer from a radioactive waste repository to the biosphere. Column experi...
متن کاملElectroremediation of Cu-Contaminated Soil
This study investigated the removal efficiency of electrokinetic remediation of copper-contaminated soil at different combinations of enhancement reagents used as anolyte and catholyte. Sodium hydroxide (at 0.1, 0.5, and 1.0 M concentrations) and distilled water were used as anolyte, while lactic acid (at 0.01, 0.1, and 0.5 M concentrations), ammonium citrate (also at 0.01, 0.1, and 0.5 M conce...
