This study assessed the ecological risk associated with heavy metals in surface sediments in a specific setting: the Wuhan wetland. Metals were extracted and characterized using the Tessier method, and the morphological distribution characteristics and correlation of Zn, Mn, Fe, Cr, and As were analyzed. The results indicated that heavy metals at the study site mainly exist in residual state forms; the Mn pollution was serious; the potential risk from Cr and As was larger; and the environmental risk from Fe and Zn was lower. In order of potential ecological harm: As > Zn > Cr > Mn. The overall risk of ecological harm was slight, but the individual region has seen moderate ecological damage because of As pollution. Because this element has a significant toxicity level, it is important to remain attentive to the pollution caused by it.
