Removal and retention o mercury in constructed treatment wetlands in the Czech republic

Popis výsledku v původním jazyce

Removal of mercury from wastewater and its sequestration in plant biomass in three constructed wetlands with horizontal subsurface flow in the Czech Republic. The constructed wetlands were designed to treat municipal sewage from 100, 150 and 700 PE. Theremoval of mercury varied between 32% and 49% aminy systems and averaged 41% with the mean outflow concentration of 0.21 ml L-1. The highest concentrations of Hg in plants were found in roots, followed by leaves, rhizomes and the lowest Hg concentrationswere found in stems. Average aboveground and belowground Hg concentrations were 0.18 mg kg-1 and 0.30 mg kg-1, respectively. These concentrations are comparable with those found in macrophytes growing in unpolluted natural wetlands. The amount of mercury sequestered in aboveground biomass did not exceed 3% of the inflow Hg loading. The amount of sediments varied between 0.6 and 10% of the dry weight of the filtration material.
