Epstein and Yapp [4] state "it is obviously necessary to calibrate more specifically the relationship between 6(D) records in cellulose nitrate from tree-ring records and known climatic records. This can probably be done best by the analysis of tree rings from widely different, well-documented environments. Such data will allow the comparison of a large variety of trees and determine the versatility of using the isotopic method for climatic temperature determination". We concur with this statement as long as "from the same population" is inserted. 

In America, researchers at the Laboratory of Tree Ring Research at the University of Arizona, Tucson, Arizona, have developed the measurement and analysis of tree ring widths using a score or so of trees in each stand to provide pluviometric maps versus time, and find that these maps have to be established separately for each region and for each set of trees, so that we can not look to ring width records versus time for information about the cyclic evolution of climate. 

We hope that analysis of stable isotopes in tree ring sequences will become an international undertaking, and that with the collaboration of many laboratories in many countries, the history of the climate in recent times, perhaps as far back as thirty thousand years, will be deduced, and that, from its determinatiop, the likely trends of climate in the near future will be predicted. 

Plants such as mung bean seedlings can be used as bioindicators for toxic elements such as As [267]. Analysis of tree rings can provide information on short-term variations in pollution sources [268]. Elemental fingerprints have also been used to identify sources of plants, including cannabis [269].
