Sažetak
Many different methods of determining the dust content are described in the literature. The choice of a method will be influenced by various considerations, which arc mentioned shortly. Dust determination will be carried out to give information for a special purpose, for instance to get an idea of the risk of silicosis. A wide range of experience has been obtained in Holland in dust determinations carried out in factories with the purpose to get an idea of the risk of certain occupational diseases, especially silicosis, lead poisoning and asbestosis. The methods chosen for these determinations are described in details, especially the use of the thermal precipitator for determining the number and the sizes of dust particles. Some results concerning the divergency of the results, obtained by these methods and the correlation between the dust content and the occurrence of silicosis arc discussed. The influence of the method used for the determination and for counting the particle, on the number of particles obtained is mentioned. The rezult, obtained by different authors are for this reason not comparable. Some standardization will be necessary to prevent a chaos or figures that would be a handicap for international discussion.
