“…The lowest bioavailable fraction of pyrene sorbed on BC is due to the fact that the sorption of HOCs on BC is generally highly non-linear and irreversible (Yu et al, 2006;Xia et al, 2011), and it might also be hard for pyrene to desorb from BC in D. magna. Research has shown that the BC has stronger binding to HOCs relative to other SOM so that the bioavailability of HOCs to organisms would be affected by the presence and quantity of sediment BC (Jia and Gan, 2014;Wang et al, 2011). Besides, we found that pyrene can also be sorbed on minerals in the present research, and this is in agreement with previous research results that contribution of mineral surface to the sorption of HOCs may not be ignored, especially for the sorbents with low content of SOC (Schoonheydt and Johnston, 2006;Meleshyn and Tunega, 2011).…”

Hydrophobic organic compounds (HOCs) tend to associate with suspended sediment (SPS) in aquatic environments; the composition and grain size of SPS will affect the bioavailability of SPS-associated HOCs. However, the bioavailability of HOCs sorbed on SPS with different compositions and grain sizes is not well understood. In this work, passive dosing devices were made to control the freely dissolved concentration of pyrene, a typical HOC, in the exposure systems. The effect of pyrene associated with amorphous organic carbon (AOC), black carbon (BC), and minerals of SPS with grain sizes of 0-50 μm and 50-100 μm on the immobilization and enzymatic activities of Daphnia magna was investigated to quantify the bioavailability of pyrene sorbed on SPS with different grain sizes and compositions. The results showed that the contribution of AOC-, BC-, and mineral-associated pyrene to the total bioavailability of SPS-associated pyrene was approximately 50%-60%, 10%-29%, and 20%-30%, respectively. The bioavailable fraction of pyrene sorbed on the three components of SPS was ordered as AOC (22.4%-67.3%) > minerals (20.1%-46.0%) > BC (9.11%-16.8%), and the bioavailable fraction sorbed on SPS of 50-100 μm grain size was higher than those of 0-50 μm grain size. This is because the SPS grain size will affect the ingestion of SPS and the SPS composition will affect the desorption of SPS-associated pyrene in Daphnia magna. According to the results obtained in this study, a model has been developed to calculate the bioavailability of HOCs to aquatic organisms in natural waters considering both SPS grain size and composition.

“…Because of their strong sorption capacities, both CNTs and black carbon have been suggested as potential remediation materials to reduce the bioavailability of HOCs in sediments or soils [7,[13][14][15]. Petersen et al [6] reported that 0.3% CNT amendment in soils decreased pyrene bioaccumulation by earthworm Eisenia fetida.…”

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.

The interest in biochar use for contaminant immobilization, which has been observed in recent years, opens up new prospects for the use of sewage sludge-derived biochar.…”
