Environmental Chemistry
Element concentrations in tree rings can be used to monitor metal pollution, fertilization, effects of acid precipitation and wild land fire on soil chemistry. We research the problems and potential of dendrochemistry and have published a number of articles on the subject. These include papers on monitoring lead and cadmium pollution from mining emissions, the effects of sulfur on molybdenum uptake over the last 500 years, barium and manganese concentrations historic changes in soil pH, factors effecting dendrochemical studies, differences in sap pH, inorganic concentrations in wood grown on different sites, and the effects of wild land fire on Ca cycling.
