| Abstract |
This report describes work carried out in order to determine which metric for very small particles best relates the exposure measurement to health hazards. An experimental rig was constructed in which it was possible to measure concentrations of ultrafine particles of varying chemical composition and particle shape. The relationships between the mass, count and active surface area of these particles, and how they are affected by chemical composition and morphology were investigated. Findings are discussed. No simple relationship was found for predicting active surface area and mass from the results of size and number measurements. The findings indicate that it is unlikely that nanoparticles will be present in a working environment in an unattached state. |
