Potential Health Effects

 

    Eye Contact: May cause eye irritation

    Skin Contact: At this time, it is not fully known whether skin penetration of nanoparticles   

    would result in adverse effects in animal models. However,topical application of raw SWCNT

    to nude mice has been shown to cause dermal irritation[Murray et al. 2007]. Studies   

    conducted in vitro using primary or cultured human skin cells have shown that both SWCNT

    and multi-walled carbon nanotubes (MWCNT) can enter cells and cause release of pro-

    inflammatory cytokines, oxidative stress, and decreased viability [Monteiro-Riviere et al.

    2005; Shvedova et al. 2003].  It remains unclear, however, how these findings may be

    extrapolated to a potential occupational risk, given that additional data are not yet

    available for comparing the cell model studies with actual conditions of occupational

    exposure. Research on the dermal exposure of nanomaterials is ongoing (www.unileipzig.

    de/~nanoderm/). Ingestion can occur from

    Inhalation: Inhalation is the most common route of exposure

    to airborne particles in the workplace.  Inhalation may lead to the formation of lung   

    Granulomas or possibly Mesothelioma. Use NIOSH Approved respirators (N100 or P100)    

    with a full face shield to prevent Inhalation.

    Ingestion: No known hazards, but may irritate gastrointestinal tract

    Acute and Chronic High concentration of dusts may be irritating to eyes, skin,

    Health Effects: mucus membranes and respiratory tract. Ingestion can occur from

    Unintentional hand to mouth transfer of materials; this has been found to happen with  

    Traditional materials, and it is scientifically reasonable to assume that it also could happen

    During handling of nanomaterials. Ingestion may also accompany inhalation exposure

    because particles that are cleared from the respiratory tract via the mucociliary escalator

    may be swallowed [ICRP 1994]. Little is known about possible adverse effects from

    the ingestion of nanomaterials.
