黄砂や煙霧とともに微生物群(バイオエアロゾル)が,アジア大陸から日本へ越境輸送され,日本での環境・健康影響が懸念される。これまで,東アジア(日中韓蒙)での黄砂を捕集する高高度調査(気球, ヘリコプター)によって,越境輸送される微生物種組成は,日本海と太平洋の沿岸で大別でき,その生体影響も異なる可能性を突き止めた。しかし,従来の観測地点は日本海沿岸に偏り,太平洋沿岸へと沈着する微生物の詳細を講じる観測データは不足している。本申請では,日本本土での観測地を拡充し,「越境微生物の国内での拡散・沈着過程」を理解すると伴に,生理学実験・疫学的調査によって,生態・健康影響を評価する。

Atmospheric samples were collected from March to June in 2014. Major ionic constituent (Na+ , NH4+ , K+ , Mg2+ , Ca2+, F- , Cl- , NO3- ,SO42-) , PM2.5 and PMc were observed. Asian Dust storm event were observed from May 28 to June 1 during this sampling period. The concentrations of F-, NO3- , K+, NH4+, Mg2+, Ca2+ in coarse fraction were increased during Asian Dust storm event. The concentrations of SO42- , NH4+, K+ were increased during Asian Dust storm event. The high correlation was recognized between Na+ and Cl- in the coarse fraction. The high correlations were recognized between SO42-, NH4+, K+, Ca2+ and PM2.5.

multi-spectral photometer of NASA/AERONET has been working at Kinki University campus in Higashi-Osaka since 2002 for measuring urban aerosols. Standard products of aerosol characteristics, e.g. optical thickness of aerosols (AOT), Angstrom Exponent (α), size distribution parameters etc, are provided on the NASA/AERONET Web page. We classify atmospheric particles into three clusters by using AOT and α of the AERONET data. We identified these clusters as desert dust, urban industrial pollution and background aerosols. Software SPSS was used for the cluster analysis.

To monitor urban atmospheric particles, we have undertaken simultaneous measurements of aerosols and suspended particulate matter (SPM) at Kinki University Campus, Higashi-Osaka, Japan, since 2004. The largest dust event recorded during our long-term observations was detected during the spring of 2006.<br>We also examined the relationship between PM_2.5 concentrations and aerosol properties obtained from radiometry using a multi-spectral photometer located at a NASA/AERONET station. We found a linear correlation between aerosol optical thickness and PM_2.5 concentrations for both ordinary days and days with dust events.
