Wetlands. 38:1245-1258
Wetlands are influenced by direct disturbances due to agricultural practices, as well as by indirect effects from the surrounding landscapes. Management and restoration require condition assessments, which are usually based on properties of the veget

We examined macrophyte-environment relationships in shallow lakes located within the Prairie Parkland and Laurentian Mixed Forest provinces of Minnesota. Environmental variables included land cover within lake watersheds, and within-lake, water and s

In a recent study, researchers found that multiple elements accumulated near the roots of Rumex crispus more under wetland conditions and element uptake was significantly greater in the plants grown under wetland compared to dryland conditions. The s

Rumex crispus was grown under wet and dry conditions in two-chamber columns such that the roots were confined to one chamber by a 21 μm nylon mesh, thus creating a soil–root interface (‘rhizoplane’). Element concentrations at 3 mm intervals be

The main goal of this study was to assess if the soils of wetlands of different condition varied in terms of element composition. The rationale was that compared to wetlands of good condition, wetlands of poor condition-which in the region have typic

We measured concentrations of multiple elements, including rare earth elements, in waters and sediments of 38 shallow lakes of varying turbidity and macrophyte cover in the Prairie Parkland (PP) and Laurentian Mixed Forest (LMF) provinces of Minnesot

Storing metal-rich mine waste (tailings) under submerged and reduced conditions can prevent the release of metals to the water column, but introduction of wetland plants on these sediments may alter the reducing environment through root oxygen diffus

A Pb–Zn tailings pond, abandoned for approximately 90 years, has been naturally colonized by Glyceria fluitans and is an excellent example of long-term metal retention in tailings ponds under various water cover and vegetation conditions. Shallow/i

Increasingly wetlands are used for treatment of metal-contaminated water or as a cover over metal-enriched mine tailings. Natural wetlands may also be contaminated with metals from anthropogenic sources. While wetland conditions tend to be favorable

The use of nanoscale zero-valent iron (NZVI, diameter 10–90 nm with an average value of 35 nm) entrapped in calcium (Ca)–alginate beads shows great promise for aqueous arsenic treatment. This research evaluated Ca–alginate-entrapped NZVI as an
