A new approach to air pollution determination using annual rings: Dendro-chemical elemental analysis of annual rings by SEM-EDS

2006
This paper presents a new approach to air pollution determined through the use of elemental analysis of the annual tree rings (ATRs) of Turkish red pine (Pinus brutia Ten.). For this aim, every annual ring width was measured on the cross-section wheels of Turkish red pine supplied from ten research points around the Kemerkoy (Gokova) thermal power ...
