英文摘要	The level and ecological impact of heavy metal pollution in the Maowei Sea mangrove are poorly understood. This work first investigated the distribution and ecological risk of Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn in Maowei Sea mangrove sediments. The results showed that heavy metals were mainly concentrated in the top 10 cm of mangrove stands, declined up to 20 cm deep, and were constant afterwards. Exceptionally, Mn concentration increased significantly with depth in the mudflat. Multiple environmental risk indices indicated that the investigated area was broadly contaminated by heavy metals and that Cd was the dominant contributor to potential ecological risks. However, the biological toxicity posed by these metals was negligible. Multivariate analyses implied that Cd, Co, Cr, Cu, Ni, Pb, and Zn originated mainly from anthropogenic sources, whereas Mn was primarily from natural processes. These findings could provide insightful information for future management of this mangrove. © 2020 Elsevier Ltd
