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

Aim. To experimentally define the optimum modes of operation ofthe nonspecific detector IBAC integrated with Cl00 sampler and BioCapture sampler in model experiments during' the work in various environmental conditions and at dispersion of the biological aerosol. Materials and methods. 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. Results. 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 1 xlO3 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. Conclusion. As a result of the experiment the effectiveness of usage of the nonspecific detector IBAC with the Cl 00 sampler and BioCapture sampler for air-monitoring on existence of PBA is proved. IBAC with C100 can be used as an inventory of the station of air-monitoring during the public events, and BioCapture is suitable for equipment of the groups of epidemiological investigation.
