“…Gomez-Eyles et al (2011) recorded a reduction in earthworm weight in a hardwood-derived biochar-amended soil contaminated with PAHs and metals relative to an unamended soil. Decreased earthworm growth rate was also observed by Jakob et al (2012) after addition of ACs to a PAHcontaminated soil. Earthworms feed by allowing dissolved organic molecules to diffuse across their gut wall.…”

“…The toxicity of metallofullerene soot is also less than that seen with C‐ENMs, such as carbon nanotubes (Scott‐Fordsmand et al ; Zhang et al ). The toxicity profile of the metallofullerene soot may, in fact, be closer to that seen with biochar or activated carbon, which can sequester environmental contaminants (Paul and Ghosh ; Jakob et al ). Similar sequestration effects were seen by other researchers who looked at the bioavailability and toxicity of environmental contaminants to earthworms in the presence of C‐ENMs (Petersen et al ; Kelsey and White ; Zhang et al ).…”

The synthesis of carbon-based nanomaterials is often inefficient, generating large amounts of soot with metals as waste by-product. Currently, there are no specific regulations for disposal of engineered nanomaterials or the waste by-products resulting from their synthesis, so it is presumed that by-products are disposed of in the same way as the parent (bulk) materials. We studied the terrestrial toxicity of soot from gadolinium metallofullerene nanomanufacturing on earthworms (Eisenia fetida) and isopods (Porcellio scaber). The metallofullerene soot consisted of carbon particle agglomerates in the nanometer and submicrometer ranges (1-100 and 101-999 nm, respectively), with metals used during nanomanufacturing detectable on the particles. Despite high metal concentrations (>100 000 mg/kg) in the soot, only a relatively small amount of metals leached out of a spiked field soil, suggesting only moderate mobility. Seven- and 14-d exposures in field soil demonstrated that the soot was only toxic to earthworms at high concentrations (>10 000 mg/kg); however, earthworms avoided spiked soils at lower concentrations (as low as 500 mg/kg) and at lower soil pH. The presence of soot in food and soil did not cause isopod avoidance. These data demonstrate that metallofullerene soot from nanomanufacturing may only be toxic to earthworms at high concentrations representative of improper disposal or accidental spills. However, our results indicate that terrestrial invertebrates may avoid soils contaminated with soot at sublethal concentrations. Environ Toxicol Chem 2018;9999:1-12.

“…If the plant is grown in soil, then the composition of soil and the number of soils to be used in the test need to be considered. Bioaccumulation in plants has been shown to vary with the texture, pH, and organic C content of soil; therefore, these factors need to be considered when choosing the type and number of test soils (Semple et al ; Sjostrom et al ; Karnjanapiboonwong et al ; Hollings et al ; Jakob et al ; Smidova et al ; Vickova and Hofman ). Exposure of the plant through the roots allows for the collection of data necessary to calculate a steady‐state or kinetic BAF value.…”

In the last decade, interest has been renewed in approaches for the assessment of the bioaccumulation potential of chemicals, principally driven by the need to evaluate large numbers of chemicals as part of new chemical legislation, while reducing vertebrate test organism use called for in animal welfare legislation. This renewed interest has inspired research activities and advances in bioaccumulation science for neutral organic chemicals in aquatic environments. In January 2013, ILSI Health and Environmental Sciences Institute convened experts to identify the state of the science and existing shortcomings in terrestrial bioaccumulation assessment of neutral organic chemicals. Potential modifications to existing laboratory methods were identified, including areas in which new laboratory approaches or test methods could be developed to address terrestrial bioaccumulation. The utility of “non‐ecotoxicity” data (e.g., mammalian laboratory data) was also discussed. The highlights of the workshop discussions are presented along with potential modifications in laboratory approaches and new test guidelines that could be used for assessing the bioaccumulation of chemicals in terrestrial organisms.
