Abstract: There is limited information on the release behavior of heavy metals from natural soils by organic acids. Thus, cadmium release, due to two organic acids (tartrate and citrate) that are common in the rhizosphere, from soils polluted by metal smelters or tailings and soils artificially contaminated by adding Cd were analyzed. The presence of tartrate or citrate at a low concentration (≤ 6 mmol L-1 for tartrate and ≤ 0.5 mmol L-1 for citrate) inhibited Cd release, whereas the presence of organic a... More
