Neutron activation analyses of wood shavings from tree rings have shown that plant tissues grown through periods of varying environmental conditions keep permanent records of the trace elements they received through nutrients from their immediate surroundings. Detailed examination of several species of trees, along with dendrochronological data, suggest the possibilities of utilizing this technique for pollution monitoring as well as for developing valuable information for environmental modelling.
