Nail dust particles were analyzed by scanning electron microscopy for size and topography. The percentage of "fines" that could be inhaled and deposited in the alveoli and bronchioles were determined by quantitative particle size analysis. Distribution representing the largest total mass was graphed between 1 and 2 microns. The authors found that 86% of nail dust would reach the bronchioles and alveoli, and 31% could be expected to deposit in these areas.
