The in vivo localization and speciation of lead (Pb) in tissues of the accumulator Sedum alfredii grown in EDTA–Pb and Pb(NO 3 ) 2 was studied by synchrotron X-ray investigation. The presence of EDTA–Pb in solution resulted in a significant reduction of Pb accumulation in S. alfredii. Lead was preferentially localized in the vascular bundles regardless of treatments but the intensities...
Reducing the transfer of contaminants from soils to plants is a promising approach to produce safe agricultural products grown on contaminated soils. In this study, 0–400mg/kg cetyltrimethylammonium bromide (CTMAB) and dodecylpyridinium bromide (DDPB) were separately utilized to enhance the sorption of PAHs onto soils, thereby reducing the transfer of PAHs from soil to soil solution and subsequently...
