The next step in assessing Arctic human health

The mapping of global pathways along which trace elements and persistent organic compounds are distributed has set the stage for parallel monitoring of levels of contamination in humans. Before expanded monitoring is undertaken, decisions must be made on which contaminants to study, what tissues to sample, how samples should be taken and evaluated, and what units should be used for consistent reporting. Once international guidelines are in place, a process should be initiated to similarly address general human health conditions. It is recommended that the next step be a global mapping of various health conditions and disease. Computer analysis should be performed to identify any correlation to known pollution plumes or deposition patterns. In addition, cultural or behavioral patterns, as well as geographic distributions, should be evaluated. The general trends would be important, as major synergistic effects might be masked if only one contaminant or health concern were monitored at a time.
