Variation among plant species in pollutant removal from stormwater in biofiltration systems
Abstract
Biofiltration systems use vegetation to improve efficiency of pollutant removal from stormwater, but little is known of how plants vary in their capacity to improve biofilter effectiveness. We used a pot trial of 20 Australian species to investigate how species vary in the removal of pollutants from semisynthetic storm water passing through a soil filter medium. Effluent levels of total suspended solids (TSS), Al, Cr, Cu, Pb and Zn were similarly low for vegetated and non-vegetated soils, with reduction to 150-fold variation in NOx and NH4+. Hence, choice of plant species may have marked effects on biofilter effectiveness.

Vegetation contributes to total metal removal in stormwater bioretention systems.
“The vegetation has been shown to contribute to the total metal removal in stormwater bioretention systems (Muthanna et al., 2007; Sun and Davis, 2007; Read et al., 2008).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
