Article Synopsis
- Identifying the best method for assessing the availability of heavy metals like cadmium (Cd) and lead (Pb) in soil is challenging and critical for understanding environmental risks and remediation efforts.
- This study compared different extraction methods (BCR, Ca(NO), and water extraction) on agricultural soil treated with various amendments to see how well they predict Cd and Pb availability.
- Results showed that water extraction better reflects the influence of soil amendments and pH on metal availability, making it a promising method for accurately evaluating these heavy metals in soil and guiding remediation strategies.
There is a long-standing debate over the effectiveness of chemical extraction methods in assessing soil metal phytoavailability. This study addresses the limitations of widely-used chemical extraction methods and presents the water-extractable pool as a more reliable indicator based on wheat pot experiments using homogenized agricultural soil amended with lime materials, phosphate, and biochar. Over 120 days' pot experiments, Cd accumulation in whole wheat plants and tissues exhibited positive relationships with water-extractable Cd concentrations at heading and maturity stage (Spearman's rho: 0.
