DEFINITION OF THE OPTIMUM MODES OF OPERATION OF AIR-MONITORING.INSTRUMENTATION FOR DETECTION OF PATHOGENIC BIOLOGICAL AGENTS IN MODEL EXPERIMENTS

Abstract

To experimentally define the optimum modes ofoperation ofthe nonspecific detector IBAC integrated with C100 sampler and BioCapture sampler in model experiments during the work in various environmental conditions and at dispersion of the biological aerosol. The nonspecific detector IBAC with the C100 sampler and the BioCapture sampler were used for air-monitoring test on existence of pathogenic biological agents (PBA). For preparation of the bioaerosols the strain of Salmonella typhimurium 9640 and a bull seralbumin were used. It is experimentally established that programming of IBAC on turning on the bioalarm system when maintaining concentration of bioaerosol in air above threshold level during 10 sec. is optimum. Its sensitivity makes 1x10³ m.c./ml of aerosol at this mode. The possibility of operation of air-monitoring instrumentation in various environmental conditions inside and outside is shown. As a result of the experi- ment the effectiveness of usage of the nonspecific detector IBAC with the C100 sampler and BioCapture sampler for air-monitoring on existence of PBA is proved. IBAC with C100 can be used as an inventory ofthe station ofair-monitoring during the public events, and BioCapture is suitable for equipment of the groups of epidemiological investigation.
