Název v původním jazyce

Greenhouse gas emissions from a constructed wetland - Plants as important sources of carbon

Popis výsledku v původním jazyce

Gas emissions (CO2, CH4, N2O) were studied in situ from the treatment bed of a constructed wetland with horizontal subsurface flow planted with Phragmites australis. The aims of the study were to estimate gas emissions as part of the carbon balance of the whole system, and to evaluate the importance of plants to the whole system. Gases, water and plants were sampled from June till October 2004. Gas emissions ranged from 4 to 309 mg CO2-C m-2 h-1 and from 0 to 93 mg CH4-C m-2 h-1. N2O emission was negligible. Only 10 % of total carbon emissions were in the form of CH4. Gas emissions were higher than carbon input in the wastewater; it was calculated that at least one third of total carbon emissions originated in plants - mostly plant exudates. The results documented the importance of plants as a source of available carbon for microorganisms in constructed wetlands which are not heavily loaded with wastewater.
