Study on the Potential of Malic Acid and Tartaric Acid Assisted in Improving the Phytoextraction of Cadmium and Lead by Sunflower ( Helianthus Annuus L.)
Abstract
Due to the toxicity, persistence, and bioaccumulation risks of heavy metals, improving soil phytoextraction efficiency has long been a critical research focus. This study investigated the use of malic acid (MA) and tartaric acid (TA) to enhance cadmium (Cd) and lead (Pb) uptake by Helianthus annuus L. (sunflower) under single and combined Cd-Pb stresses, and the effect of adding different concentrations of LMMOAs (malic and tartaric acids) on phytoextraction of heavy metals were studied by potted plants simulation experiment. The results demonstrated that exogenous application of malic acid (MA) and tartaric acid (TA) significantly promoted the growth of sunflower plants under Cd/Pb stress across all tested concentrations. Specifically, MA and TA enhanced both heavy metal uptake and translocation efficiency in sunflowers: the highest Cd accumulation (Cd10+MA30 treatment) and Pb accumulation (Pb100+MA30 treatment) were observed, respectively. Correlation analysis revealed positive relationships between Cd/Pb uptake/translocation coefficients and soil metal concentrations, while translocation capacity (root-to-shoot transfer) remained unaffected by acid amendments. Notably, increased root Cd uptake directly promoted shoot Cd translocation (p < .05) and concurrently enhanced Pb uptake in aerial tissues. This study highlights the potential of MA and TA as bio-enhancers for sunflower-mediated phytoextraction of Cd/Pb-contaminated soils, providing critical insights for optimizing heavy metal remediation strategies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
