Before we are concerned about potential health effects from these chemicals, there must be a completed route of exposure.  Indeed, many tribes have used or wish to use these objects in ceremony.  It is important to understand that these objects are sacred to the tribe and are often considered to be living entities.  There are prescribed rituals for handling, storing, and caring for them.  Often these involve keeping the objects in tribal member’s homes, or in places where food items are stored.  Participation in ceremony may include very small children and extend to the elderly.  (READ SLIDE)  One of the difficulties we encounter with “quantifying” the exposure is the lack of specific data on each artifact including which chemicals were applied and the amounts.  Thus many tribal members may be at risk for exposure to chemical preservatives.
