“…The effect of variable AC particle size on aqueous concentrations appears to be generally in line with that observed on HOC bioaccumulation (Zimmerman et al ; Tomaszewski et al ; Kupryianchyk et al ). It has been shown that at equal concentration, AC, with a smaller particle size and therefore higher surface area, facilitates HOC sequestration and results in lower bioaccumulation in aquatic organisms (McLeod et al ; Sun and Ghosh ; Kupryianchyk et al ).…”

“…Futhermore, the efficiency of AC application has been shown to be affected by the presence of other sorptive materials like black C or weathered oil (Jonker et al 2006;Koelmans et al 2009a). Sediments with high content naturally present black C or oil may sequester HOCs very effectively, thus limiting the added value of AC amendments (Kupryianchyk et al 2012a).…”

Contaminated sediments can pose serious threats to human health and the environment by acting as a source of toxic chemicals. The amendment of contaminated sediments with strong sorbents like activated C (AC) is a rapidly developing strategy to manage contaminated sediments. To date, a great deal of attention has been paid to the technical and ecological features and implications of sediment remediation with AC, although science in this field still is rapidly evolving. This article aims to provide an update on the recent literature on these features, and provides a comparison of sediment remediation with AC to other sediment management options, emphasizing their full-scale application. First, a qualitative overview of advantages of current alternatives to remediate contaminated sediments is presented. Subsequently, AC treatment technology is critically reviewed, including current understanding of the effectiveness and ecological safety for the use of AC in natural systems. Finally, this information is used to provide a novel framework for supporting decisions concerning sediment remediation and beneficial reuse.

“…To our knowledge, these are the first published values of K PCBi BC derived from measurements of both native PCBs and BC. Other reports represent determination of the partitioning by calculation (Kupryianchyk et al, 2012; Lohmann et al, 2005; Moermond et al, 2005) or from measurements of different carbonaceous materials spiked with non-native PCBs (Bucheli and Gustafsson, 2003; Jonker and Koelmans, 2002). Our values are in the same range of other reported values (~± 1 log unit), with some remarkable agreements (e.g.…”

Sediment pore water distribution coefficients of PCB congeners in enriched black carbon sediment

More than 2300 sediment pore water distribution coefficients (KPCBi ds) of 93 polychlorinated biphenyls (PCBs) were measured and modeled from sediments from Indiana Harbor and Ship Canal. KPCBi ds were calculated from previously reported bulk sediment values and newly analyzed pore water. PCBs in pore waters were measured using SPME PDMS-fiber and ∑PCB ranged from 41 to 1500 ng L−1. The resulting KPCBi ds were ~ 1 log unit lower in comparison to other reported values. A simple model for the KPCBi d consisted of the product of the organic carbon fraction and the octanol-water partition coefficient and provided an excellent prediction for the measured values, with a mean square error of 0.09 ± 0.06. Although black carbon content is very high in these sediments and was expected to play an important role in the distribution of PCBs, no improvement was obtained when a two-carbon model was used.

“…Recently, in situ sediment remediation technology introducing sorbent amendments into contaminated sediments effectively reduces organic contaminant bioavailability and has provided a new direction in contaminated sediment management . Adsorbents most frequently used for this purpose include activated carbon (AC) Ghosh 2011, 2013;Kupryianchyk et al 2012;Tomaszewski et al 2007). Adding activated carbon (AC) to sediment has been proposed as a remediation technique to reduce HOC release to the overlying water (Cho et al 2007;Oen et al 2011;Sun and Ghosh 2008;Zimmerman et al 2004).…”

Adding activated carbon (AC) to sediment has been proposed as an in situ sediment remediation technique. To date, it is not clear whether this technique is effective in the treatment of heavy metal-contaminated sediment in the presence of bioturbators. In the present study, we compare the ability of granular-activated carbon (GAC) and powderactivated carbon (PAC) to reduce Cu, Zn, and Pb pore water concentrations at environmentally relevant concentrations in the absence and presence of Chironomid larvae. Compared to untreated sediment, PAC and GAC addition in the absence of Chironomid larvae resulted in reductions of free Cu concentrations of 78 and 66 % just below the sediment-water interface after 28 days, respectively. While for Pb and Zn these concentration reductions were only 40 and 38, 19 and 25 %, respectively. The presence of Chironomid larvae in untreated, and GAC sediment generally increased the free heavy metals concentrations in pore water, especially in the deeper layers. In comparison with untreated sediment, the coexistence of AC enhanced the accumulation of heavy metals, especially for PAC. This increased bioaccumulation may decrease the survival of Chironomid larvae. The result indicated that ACs may not be suitable for the remediation of heavy metalcontaminated sediments.
