Abstract

Chemical states of iron have been investigated by57Fe Mössbauer technique for the barks of Japanese cedar collected from urban and mountainous area of Japan. The Mössbauer spectra of all outer bark samples show two overlapping doublets and one sextet ascribable to paramagnetic ferrous, paramagnetic ferric and magnetic iron, respectively, whereas an inner bark sample consists only of the two doublets. The bark sample from urban area shows the higher relative amount of magnetic component and the smaller ferrous to ferric ratio. These features of iron species in the bark sample indicate that the bark sample can supply a more effective indicator of human activities than airborne particles collected directly by evacuation with an air sampler.
