- Abstract In the field of occupational hygiene much consideration is devoted to the uptake through the human airways, but there are also reports of irritations, complaints and hazards or potential hazards due to particle deposition onto the eyes. There is a need for data regarding the dependence of the deposition rate on particle size and environmental parameters in order to formulate sampling criteria and to find dose-response relations. The deposition of airborne particles onto the human eye was studied by making use of a dummy, the eyes of which were covered with pieces of transparent sticky foil. The dummy was exposed to airborne particles in a wind tunnel. The airborne particle concentration was simultaneously measured using an Aerodynamic Particle Sizer (APS, TSI Inc., U.S.A.). The deposited particles were counted using an optical microscope equipped with an image analyser. For the particle sizes (2–30 μm), wind velocities (0.5 and 1.0 m s−1), wind directions (0, 90 and 180°) and turbulence intensities (1.3 and 19%) employed in this study, deposition velocities onto the eyes were determined to be in the range of 0.001–1 cm s−1.

- Studies have been performed on the deposition of airborne particles onto the human eye. A mannequin with sticky transparent foils covering its eyes is exposed to particles of fused alumina in a wind tunnel. The size distribution of the airborne particle is simultaneously measured with an Aerodynamic Particle Sizer. The particles on the foils are counted and measured with an optical microscope connected to an image analyzer. Deposition velocities have been determined for particles with aerodynamic diameters over the range 2 to 32 μm with different orientations of the mannequin to the wind direction at an air velocity of 1 m/s. The deposition velocity is in the order of 0.01 cm/s.
