“…As shown in Figure 2, the BSAF of chrysene increased slightly when char-stalk content in sediment increased from 1.5 to 5.0%. Some studies showed that the gut fluid of deposit-feeding organisms could solubilize significant concentrations of PAHs from black carbon [39]. Thus, the assimilation of char-associated PAHs by C. plumosus larvae may occur as well, though this phenomenon was not as significant as that in MWNT-amended sediments.…”

Carbonaceous materials (CMs), including carbon nanotubes (CNTs), and black carbon have been suggested as potential remediation materials for hydrophobic organic contaminants (HOCs) in sediments or soils. However, the concentration-dependent and potential effects of CMs on the decrease in HOC bioavailability are not well understood. In this research, the effects of two types of multiwalled CNTs (MWNT-1 and MWNT-2) and chars (char-stalk produced from stalk and char-wood from wood) on the bioaccumulation of polycyclic aromatic hydrocarbons (PAHs), including phenanthrene, pyrene, and chrysene, in the benthic organism Chironomus plumosus larvae were studied. When CM content was 1.5% or less in sediments, biota-sediment accumulation factor (BSAF) values for PAHs decreased sharply as CM increased. However, when char and MWNT-1 content was greater than 1.5% in sediments, reduction rates of BSAF were slight. Furthermore, when MWNT-2 content was greater than 1.5%, BSAF values were elevated. This indicated that the MWNT-associated PAHs may have been absorbed by larvae through particle ingestion, and suggested that some CNTs may not be suitable for the remediation of HOC-contaminated sediments because they probably could increase the exposure risk of PAHs to benthic organisms, possibly because of their unique structure.

“…However, while these markers may be present in tires, several limitations in their application make estimating tread polymer or TRWP concentration uncertain. For example, Voparil, et al 18 estimated that in heavy traffic areas, sediment could contain as much as 15% tread polymer. This estimate, however, was based on a study relying on the marker 2,4MoBT in sediment where an internal standard was not used, and analyte recovery was not evaluated (ref 2 in SI Table S1).…”

Impacts of surface runoff to aquatic species are an ongoing area of concern. Tire and road wear particles (TRWP) are a constituent of runoff, and determining accurate TRWP concentrations in sediment is necessary in order to evaluate the likelihood that these particles present a risk to the aquatic environment. TRWP consist of approximately equal mass fractions of tire tread rubber and road surface mineral encrustations. Sampling was completed in the Seine (France), Chesapeake (U.S.), and Yodo-Lake Biwa (Japan) watersheds to quantify TRWP in the surficial sediment of watersheds characterized by a wide diversity of population densities and land uses. By using a novel quantitative pyrolysis-GC/MS analysis for rubber polymer, we detected TRWP in 97% of the 149 sediment samples collected. The mean concentrations of TRWP were 4500 (n = 49; range = 62-11 600), 910 (n = 50; range = 50-4400) and 770 (n = 50; range = 26-4600) μg/g d.w. for the characterized portions of the Seine, Chesapeake and Yodo-Lake Biwa watersheds, respectively. A subset of samples from the watersheds (n = 45) was pooled to evaluate TRWP metals, grain size and organic carbon correlations by principal components analysis (PCA), which indicated that four components explain 90% of the variance. The PCA components appeared to correspond to (1) metal alloys possibly from brake wear (primarily Cu, Pb, Zn), (2) crustal minerals (primarily Al, V, Fe), (3) metals mediated by microbial immobilization (primarily Co, Mn, Fe with TOC), and (4) TRWP and other particulate deposition (primarily TRWP with grain size and TOC). This study should provide useful information for assessing potential aquatic effects related to tire service life.

“…The time of AC treatment varied from two minutes (Sun and Ghosh, 2007) to 780 days (Tomaszewski et al, 2007). In some articles, this information was not available (Voparil et al, 2004;Cornelissen et al, 2006a;Burgess et al, 2009). The work of Sun and Ghosh (2007) was specifically investigating the time of AC treatment.…”

Activated carbon amendment to remediate contaminated sediments and soils: a review

Activated carbon (AC) amendment for reduction of contaminant exposure in polluted soils and sediments has recently emerged as a promising remediation technique. Here, we provide a short overview of the state-of-the-art in activated carbon (AC) amendment to such sites. Most studies not only in sediments but also in soils were carried out in the laboratory and only a few in the field. Consequently, practical experience at the field scale is largely lacking, and feasible engineering approaches for AC amendment still need to be developed, especially for soils. The effectiveness of the AC treatment was evaluated by comparison of pollutant concentration reduction in the various endpoints with those in the unamended control matrix. Endpoints in use comprise pollutant concentrations in benthic organisms, depletive and non-depletive methods to quantify pollutant exposures, as well as various toxicity endpoints of plants. Half of the studies in soils and 68% of the studies in sediments showed reduced pollutant availabilities of >50% after AC amendment. Observed low reductions (<50%) might be due to low exposure time, insufficient equilibrium time for coke breeze, biochar, and granulated AC, overload of AC material, different uptake pathways of benthic organisms, and pollutant reductions outside the dynamic range of toxicity endpoints. Further research is needed to establish ideal AC amendment conditions to sediments and soils, leading to significantly reduced pollutant bioavailability.
