| Outline of Final Research Achievements |
First of all, we investigated the development of a highly sensitive collection method and a recovery improvement method for about 500 kinds of semi- and non-volatile chemicals concerned about air pollution. Second, we investigated a conditions of simultaneous analysis for carbonyl compounds. Third, we investigated the continuous monitoring of atmospheric concentrations and measurement of exhaust gases from automobiles and motorcycles, etc. for semi- and low volatile chemicals and carbonyl compounds. Fourth, based on the data obtained by these approaches, the situation of air pollution by semi-volatiles and carbonyl compounds was analyzed. The detection frequency and concentration were discussed their time variability, the reletion between weather conditions, PRTR atmospheric release amounts and the emmission source ando so on.

| Academic Significance and Societal Importance of the Research Achievements |
有害化学物質の環境排出量の90％以上の排出先となっている大気環境に着目し、約500種類に及ぶ半・難揮発性物質に加え、環境中でも生成するアルデヒド類やケトン類などのカルボニル化合物を対象に、大気環境中での包括的な一斉分析を実施したものであり、希少なデータを提示することができた。また、道路近傍や自動車・バイクなどの移動体、工場等発生源近傍、一般住宅地域など、発生源の把握に参考となる希少なデータを提示することができた。これらのデータ収集手法に目途が立ったことで、大気環境中の未規制化学物質の科学的なばくろ評価が進み、環境リスク最小化に向けた化学物質管理の効率的な施策展開が可能になると考えられた。
