The use of chelating agents in remediation of cadmium (Cd)-contaminated soils by leaching has gained popularity. However, the environmental risks associated with this practice, particularly its impact on soil Cd phytoavailability, remain poorly understood. This study investigated the effects of three common chelating agents, including citric acid, nitrilotriacetic acid (NTA), and glutamate diacetate acid (GLDA), on soil Cd phytoavailability through soil incubation (14 days) and Sedum plumbizincicola pot experiments (160 days).
