Large Constructed Wetlands for Phosphorus Control: A Review
2016
Water
Preserved Fulltext
Stormwater systems display differences between wet and dry season behavior, which appear to be flow-driven. Several models of system performance have been developed, both steady and dynamic. ...
Thirty-seven such wetlands have been built and have good data records, with a median size of 754 ha. All are successfully removing phosphorus from a variety of waters. ...
The acquisition of that data was the result of massive efforts and expenditures.
Conflicts of Interest: The author declares no conflict of interest. ...

Particulate phosphorus (PP) is often the largest component of the total phosphorus (P) load in stormwater. ...
Fine-resolution measurement of particle sizes allows us to investigate the mechanisms behind the removal of PP in stormwater wetlands, since the diameter of particles influences the settling velocity and ...

To address this, I investigated the extent, drivers, and consequences of MeHg production in important types of managed wetlands, as well as the response of MeHg to specific management interventions. ...
The direct or indirect management of wetlands is pervasive, but many questions remain regarding the impact of wetland management on MeHg biogeochemistry. ...
We would especially like to acknowledge the tireless analytical excellence of Haiyong (Planck) Huang for assistance in MeHg and THg data collection. ...
