TL;DR: The results showed that EDDS was more effective than EDTA at increasing the concentration of Cu in corn and beans, and that EDTA was better at solubilizing Pb and Cd than EDDS.

TL;DR: Results of the sequential chemical extraction of soil samples showed that the Pb concentrations in the carbonate-specifically adsorbed and Fe-Mn oxide phases were significantly decreased after EDTA treatment, indicating that EDTA solubilized Pb mainly from these two phases in the soil.

TL;DR: The chemical forms of heavy metals in sediment cores of the Pearl River Estuary were studied using a sequential chemical extraction method and the 206Pb/207Pb ratios in the exchangeable fraction were the lowest among the five fractions, particularly in top sediments, showing the anthropogenic inputs ofheavy metals from recent rapid industrial development in the surrounding region.

TL;DR: In this article, the translocation ratio of Pb from vetiver roots to shoots was significantly increased after 5.0 mmol EDTA kg−1 of soil application and nearly 126 mm of rainfall irrigation.

TL;DR: In a pot experiment, the potential use of 10 plant species, including six dicotyledon species and four monocotylingon species, was investigated for the EDTA-enhanced phytoextraction of Pb from contaminated soil, with the highest amount of phy toextracted Pb achieved in sunflowers.
