Evaluating the utility of natural vegetation in assessing arctic accumulation of air toxics. Final draft report
Accumulation of toxic, airborne pollutants in the arctic and sub-arctic is of growing concern to scientists. Levels of atmospheric deposition of these elements in the arctic prior to anthropogenic augmentation of their cycling are unknown, and in many cases, current concentrations of these elements in surface vegetation and their rates of deposition in the arctic are also unknown. The purpose of this document is to provide species-specific information on the use of natural vegetation to monitor trace-metal deposition and accumulation in high-latitude regions of North America. Data will help in research design for arctic contamination studies, because they aid in estimating expected concentration ranges and between and within-site variability of element concentrations in vegetation samples.
