6Evaluation

6.1. Cancer in humans

There is inadequate evidence in humans for the carcinogenicity of carbon nanotubes.

6.2. Cancer in experimental animals

There is sufficient evidence in experimental animals for the carcinogenicity of MWCNT-7 multiwalled carbon nanotubes.

There is limited evidence in experimental animals for the carcinogenicity of two types of multiwalled carbon nanotube with dimensions similar to MWCNT-7.

There is inadequate evidence in experimental animals for the carcinogenicity of multiwalled carbon nanotubes other than MWCNT-7.

There is inadequate evidence in experimental animals for the carcinogenicity of single-walled carbon nanotubes.

6.3. Overall evaluation

MWCNT-7 multiwalled carbon nanotubes are possibly carcinogenic to humans (Group 2B).

Multiwalled carbon nanotubes other than MWCNT-7 are not classifiable as to their carcinogenicity to humans (Group 3).

Single-walled carbon nanotubes are not classifiable as to their carcinogenicity to humans (Group 3).
