| Outline of Final Research Achievements |
Dry marine sediment and sludge deposit may become a source of suspended particulate matter (SPM) after the tsunami disaster in 2011, Japan. Further understanding of interaction between SPM and bioaeosol in the atmosphere may contribute to prevent spread of pathogenic microbes through air. This work investigates the effect of marine deposits and some other type of SPM to attribute a survival of biological aerosol in the tropospheric condition. Experiments were carried out with a reaction chamber to examine different types of SPM and bioaerosol in a laboratory. Results indicated that the SPM of marine deposit and model enteric bacteria had significantly higher survival rate than other SPMs examined. The different SPMs may play a significant role for the survival of airborne bacteria and other pathogenic microbes. It is necessary to further investigate the interactions between SPM and bioaerosols to understand factor influencing spread of pathogens to safeguard public health.
