Sanding dust from nanoparticle-containing paints: Physical characterisation. Koponen, I. K., Jensen, K. A., & Schneider, T. Journal of Physics: Conference Series, 151(1):012048, February, 2009. ![Sanding dust from nanoparticle-containing paints: Physical characterisation [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex Increasing use of nanoparticles in different industrial applications has raised a new potential health risk to the workers as well as to the consumers. This study investigates the particle size distributions of sanding dust released from paints produced with and without engineered nanoparticles. Dust emissions from sanding painted plates were found to consist of five size modes; three modes under 1 ?m and two modes around 1 and 2 ?m. We observed that the sander was the only source of particles smaller than 50 nm and they dominated the number concentration spectra. Mass and surface area spectra were dominated by the 1 and 2 ?m modes. Addition of nanoparticles caused only minor changes in the geometric mean diameters of the particle modes generated during sanding of two paints doped with 17 nm TiO2 and 95 nm Carbon Black nanoparticles as compared to the size modes generated during sanding a conventional reference paint. However, the number concentrations in the different size modes varied considerably in between the two NP-doped paints and the reference paint. Therefore, from a physical point of view, there may be a difference in the exposure risk during sanding surfaces covered with nanoparticle-based paints as compared to sanding conventional paints.
