A New Apparatus to Study the Microbiological Contamination of Air.

摘要

The new apparatus allows to determine accurately the total number of microorganism particles in a unit volume of air, and to determine the size of respirable fraction of microorganism aerosol which could penetrate pulmonary alveola. The apparatus permits to perform under various conditions the evaluation of microbiological health hazards, even in the case of air very strongly contaminated with microorganisms such as, for instance, in an environment contaminated with organic dusts. There is possibility of an adaptation of apparatus to perform determinations of the contamination of air with impurities of other character. The described apparatus could find broad utilization in studies connected with protection of the natural environment of man, as well as in studies in the fields of medicine, agro-technology and zoo-technology.
