| 英文摘要 | Extreme events, such as summer heat and drought (SHD), constitute significant natural disasters that adversely affect socio-economic development and the environment, with their frequency increasing in recent decades. However, the mechanisms underlying mobilization and liberation of heavy metals (HMs) in the sediment pore water of estuarine wetlands subjected to SHD remain poorly understood. In this study, high-resolution dialysis (HR-Peeper) was utilized to monitor SHD-related variations of HMs (As, Cd, Co, Fe, Mn, Mo, Pb, Sb, and V) in the sediment pore water of the Jiulong River Estuary, China. The results demonstrated that SHD elevated the concentrations of HMs significantly and transformed most HMs from their initial role as sinks to sources for the overlying water. Based on the geochemical relationships between Fe/Mn and other HMs, the latter can be categorized into three groups: (1) Mo, Sb, and V; (2) As and Co; (3) Cd and Pb. SHD significantly accelerated the decomposition of organic matter, enhanced the reduction of Fe/Mn-oxides, and promoted the dissolution of minerals/sulfides, each of which substantially increased the concentrations of the corresponding metal categories. This study provides novel insights into the effects of extreme climate change on the migration and transformation of HMs in estuarine wetlands. |
