Abstract

Carbon nanotubes have distinctive characteristics, but their needle-like fibre shape has been compared to asbestos, raising concerns that widespread use of carbon nanotubes may lead to mesothelioma, cancer of the lining of the lungs caused by exposure to asbestos. Here we show that exposing the mesothelial lining of the body cavity of mice, as a surrogate for the mesothelial lining of the chest cavity, to long multiwalled carbon nanotubes results in asbestos-like, length-dependent, pathogenic behaviour. This includes inflammation and the formation of lesions known as granulomas. This is of considerable importance, because research and business communities continue to invest heavily in carbon nanotubes for a wide range of products under the assumption that they are no more hazardous than graphite. Our results suggest the need for further research and great caution before introducing such products into the market if long-term harm is to be avoided.

Recomputing p-values needs the paper’s full text.

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?

  • One reason for reduced CNT toxicity is that many CNT materials were tested in agglomerate state, and such granular agglomerates are not expected to show fibre-specific toxicity.

    “One reason for reduced CNT toxicity was attributed to the fact that many CNT materials were toxicologically tested in agglomerate state as CNTs can already be synthesized as highly entangled agglomerates, can spontaneously re-agglomerate after dispersion, or, if thin and flexible, can self-tangle into granules. Such granular agglomerates are not expected to show fibre-specific toxicity.”
  • Carbon nanotubes were found not to be consistently toxic despite the fibre-pathogenicity paradigm's prediction.

    “However, a specific class of nanoscale materials, carbon nanotubes (CNTs), was found not to be consistently toxic despite the fibre-pathogenicity paradigm’s prediction [17, 18].”

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.
