| Research Abstract |
Air pollution which observed in spring of 2010-2012 in the northern Kyushu was studied, focusing on its environmental dynamics and adverse health effects on humans. Atmospheric environment in the western Japan was found to be worsening, so that recently a haze was pretty often observed over not only cities but also other places from early spring to rainy season. Air pollutants contained are some chemicals, yellow-sand and pollens. The combined effect of those compounds was feared to increase rhinitis patients, allergic and respiratory diseases. Above all on May 20 and 21 in 2010, the northern Kyushu was covered with a dense fog which was assumed to be carried from the Asian Continent. This fog brought about traffic turmoil in trains and flights due to the poor visibility. The anthropogenic components such as black carbon, sulfate, lead, ozone and benzene were detected on this period. The similar smog was observed in Los Angeles in 1945.We also identified for the first time that black-colored yellow-sand which had previously been exposed to air pollutants.
