The solid binding force (kL) of Sb to alkaline soils is less than that of acidic and neutral soils; therefore, alkaline soils pose a higher risk of secondary pollution. Variation partitioning analysis showed that water-soluble Sb was the predominant factor responsible for the observed decrease in DHA. Ecological doses (ED10) based on water-soluble Sb fluctuated from 3.4 to 360 mg kg−1 in soils. Soil properties, such as pH, total phosphorus, amorphous Fe, and clay content, played a crucial role in Sb toxicity to DHA. This study highlighted the importance of water-soluble Sb while evaluating the Sb toxicity in soils. Thus, the study is useful in risk assessment and remediation of Sb-contaminated soils.]]> Fri 05 May 2023 11:32:09 AEST ]]>
