Uranium uptake by hydroponically cultivated crop plants

Uranium uptake in Nicotiana sp. under hydroponic conditions

“…A similar result was achieved for Helianthus annuus L. and B. juncea using medium without phosphates (Vera Tomé et al, 2009). The presence of phosphate in the solution caused lower availability of uranium due to a complex formation and resulted in a decrease of uranium content in the roots and its limited transfer into the shoots (Soudek et al, 2011a;Rufyikiri et al, 2006).…”

“…A number of authors dealt with the effects of various soil amendments on uranium desorption from soil and developed techniques to trigger uranium hyperaccumulation in plants (Mkandawire et al, 2005;Vandenhove et al, 2001). Additions of chelating agents or organic acids into the soil may increase the intake of uranium and other metals and their transport to above-ground tissues of Brassica juncea (Duquène et al, 2009), Brassica oleracea and Sinapis alba (Soudek et al, 2011a). A similar result was achieved for Helianthus annuus L. and B. juncea using medium without phosphates (Vera Tomé et al, 2009).…”

Biogeochemistry of uranium in the soil-plant and water-plant systems in an old uranium mine

“…The potential of some terrestrial and aquatic plants to accumulate U has been observed in several studies performed both in field or laboratory conditions, supporting their possible use in U biomonitoring (e.g., Caldwell et al, 2012;Steubing and Haneke, 1993), and/or in phytoremediation of U-contaminated water or wastewater (e.g., Dushenkov et al, 1997;Jha et al, 2016;Soudek et al, 2011), and U-contaminated soil or solid waste (e.g., Li et al, 2011;Ramaswami et al, 2001;Stojanović et al, 2009). While studying the phytoremediation of U-contamination in abiotic matrices, it is revealed that natural potential of plants may be enhanced by adopting the following measures: (i) combination with fungus (e.g., He et al, 2015); (ii) genetic transformation (e.g., Eapen et al, 2003); and (iii) using soil amendments such as chelators (e.g., Duquène et al, 2009;Jagetiya and Sharma, 2013).…”

Irrigation Water Quality—A Contemporary Perspective

“…In their recent study, Wang et al [191] found that volatile organic compounds released by plant growth-promoting rhizobacteria increases both selenium and iron uptake. Uranium is another geogenic, potentially toxic contaminant [192] and studies in nutrient culture show its uptake by crops [193,194]. Several studies confirmed that irrigation water contaminated with uranium has an impact on crop quality though less to soil contamination by uranium [195][196][197].…”
