Paper Abstract

The first approximation in the evaluation of potential health hazards has been carried out for particles in laser smoke aerosols. The amount of emitted aerosol mass per second has been measured for typical lasers and application parameters. Combined with investigations of the flow distribution in operating rooms for two different types of ventilation, the estimated concentration values as a function of time during and after vaporization of tissue has been calculated and measured at certain points in the OP. Due to turbulence in the flow distribution high concentrations have been determined. Neglecting all potential toxic effects by the gaseous components or adsorbed vapors and liquids at the particle surface and regarding the aerosols as dust/air mixtures only the determined concentrations are of the same order of magnitude as typical threshold limit values for workplace pollution with inert dusts.
