隣接する地域間における大気汚染物質濃度の相互因果解析

抄録

We have analyzed the interaction of the air pollution gases concentration between neighboring places in Kitakyushu area by KM₂O-Langevin equations theorem, which provides the causality between different time series. From the analyses on SO₂, NO₂ and NO gases concentrations on 100 hours basis from 1980 to 1986, we have recognized a strong causality on SO₂ in 1980 and 1986, but not noticiable in other cases. We have also recognized a moderate causality on NO₂ in 1986.
