Spatial accumulation and strength of affiliation of heavy metals in bioretention media

Jones, Philip Sumner, Davis, Allen P.·2013·Journal of Environmental Engineering

Abstract

On-site sequestration and accumulation of heavy metals in bioretention cells introduces the potential for short- and long-term management concerns regarding the metals’ environmental availability, human health impacts, and implications for maintenance practices. Media samples from a 4-year-old bioretention cell were collected across the cell surface and to a depth of 90 cm to assess the spatial distribution of accumulated lead, copper, and zinc in the media. Analyses consisted of total metal, a five-step sequential extraction, bioavailable lead, and media pH and organic matter content. Metal concentrations in the media have increased substantially over the original levels but are well below regulatory cleanup thresholds. Metals are strongly bound to bioretention media and are largely immobile. Lead bioavailability is comparable to generic soil estimates. Most metal accumulation is near the inflow point in the top 3–12 cm of media. Based on trends observed after 4 years of operation, many years of capacity are estimated to remain in the cell with respect to metals. Regulatory cleanup thresholds are likely to be first reached at a localized hotspot near the inflow point, although routine maintenance actions may be able to delay attainment of such thresholds indefinitely.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Sequential extractions of filter materials from two approximately four-year-old full-scale bioretention facilities in Washington D.C. and Maryland (USA) indicated that adsorbed metals were strongly bound to the bioretention filter material and largely immobile (not in the exchangeable fraction).

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.
