Constructed wetlands are artificial ecosystems designed to replicate natural wetland processes. Microbial communities play a pivotal role in cycling essential elements, particularly sulfur, which is crucial for trace metal fixation and remobilization these ecosystems. By their response environment, microbial act as biological indicators of the performance. To address knowledge gaps pertinent changes bioavailability relation activities H-02 constructed wetland, we performed this study...

Sediments in aquatic systems often act as a major sink for contaminants. Diffusive gradient thin films (DGTs) and situ equilibrium dialysis samplers (peepers) are two pore water sampling devices that overcome the problems associated with conventional methods. In present study, DGTs peepers were used to study spatial seasonal effects (cool months, October-February; warm May-September) on metal bioavailability H-02 constructed wetland versus source role of sediments by calculating resupply...

Major weather events contribute to the mobility and remobilization of legacy mercury (Hg) contamination sequestration within sediments. Remediation using biochar as a soil amendment is useful technique immobilize decrease Hg toxicity. This study explored whether application effective at stabilizing labile (LaHg) from floodplain sediment. Controlled mesocosms simulating flooding conditions were conducted. Floodplain sediment, which experiences annual periodic flooding, was collected. Sediment...
