A personal dust sampler simulating variable human lung function.
  1. R Kucharski

    Abstract

    In a prototype of a new personal dust sampling system (PDS) the speed of air sampling in the breathing zone is related to the pulmonary ventilation rate of the wearer, using the correlation between pulmonary ventilation and pulse rate that is monitored by electrodes fastened on the sampler wearer's chest. The method of calibration and the results of dust chamber and field measurements are presented. The prototype of the new sampler was tested in a lead and zinc smelting plant against a routine stationary sampler and typical personal sampler. Personal exposure using all the above mentioned devices has also been assessed, and the PDS gives satisfactory results in use.
