Abstract
- In order to explore the absorption capacity of Suaeda heteroptera for heavy metals in coastal wetlands under tidal conditions, a tidal simulation device for Suaeda heteroptera habitat was designed based on the field conditions of Red Beach in China to investigate the absorption capacity of Suaeda heteroptera at different growth stages for heavy metals. The results showed that the on-site data monitoring at the Red Beach of Panjin in China revealed that zinc had the highest detected values in the water, sediment, and Suaeda heteroptera samples, and the absorption of heavy metals followed the order of Zn > Pb > Cu. Under tidal simulation conditions, the maximum absorption values of copper, lead, and zinc by Suaeda heteroptera at different growth stages were in the order of Zn > Pb > Cu, with metal content of 59.72 mg/kg, 46.73 mg/kg, and 15.70 mg/kg, respectively. These findings were consistent with the trend observed in the on-site monitoring data, and the values in the early growth stage were higher than those in the later growth stage. This result reveals the absorption capacity of Suaeda heteroptera for heavy metals and provides a theoretical basis and data support for wetland ecological restoration. [ABSTRACT FROM AUTHOR]
