| the effect of edta on helianthus annuus uptake, selectivity, and translocation of heavy metals when grown in ohio, new mexico and colombia soils. | the use of two edta concentrations for enhancing the bioavailability of cadmium, chromium, and nickel in three natural soils (ohio, new mexico and colombia) was investigated. the resulting uptake, translocation and selectivity with helianthus annuus after mobilization were also examined. in general, plants grown in the sandy-loam ohio soil had a higher uptake that resulted in a selectivity and total metal content of cd>cr>ni and 0.73 mg and cr>cd>ni and 0.32 mg for 0.1 and 0.3 g kg-1 edta, respe ... | 2005 | 15664616 |
