dendrochemistry

dendrochemistry

[‚den·drō′kem·i·strē]
(chemistry)
The analysis of the chemical composition of tree rings for naturally occurring or human-manufactured chemicals, especially the mineral elements, to understand the impact of pollution in the air, or surface-water or ground-water supply in ecosystems, or to detect environmental changes over time.

Although the field is less than a century old, there are now scientists who study dendroclimatology, dendrovolcanology, dondropyrochronology, dendrochemistry.
METHODS: We used dendrochemistry, the study of element concentrations through time in tree rings, in Fallon to assess temporal variability of airborne tungsten and cobalt since the late 1980s.
RESULTS: The Sweet Home test case confirms the accuracy of dendrochemistry for showing temporal variability of environmental tungsten.
KEY WORDS: childhood leukemia, cobalt, dendrochemistry, Fallon, Nevada, tungsten.
Dendrochemistry has been used in studies of temporal patterns of various heavy metals in the environment, including lead (Hagemeyer and Weinand 1996), nickel (Yanosky and Vroblesky 1992), cadmium (Guyette et al.
To independently test the accuracy of dendrochemistry specifically for tungsten, we repeated this experiment in a different small town that has a known source of airborne tungsten.
