Fecal copper (Cu) provides an estimate of very recent exposure to Cu, and to some extent biliary Cu excretion. The biliary / fecal route is the main route of excretion for Cu from the body.
Foods highest in Cu include organ meats (liver), shellfish, firm tofu, spirulina, beans/legumes, seeds and nuts, and dark chocolate. Other potential sources of Cu include contaminated food or drinking water, excessive Cu supplementation, occupational / environmental exposures, and wood preservatives. “Green” wood that has been treated with copper (AAC, ACQ, ACZA), and possibly chromium and arsenate (CCA) can be a source of those elements; respiratory and contact protection should be implemented when working with such exterior wood. There have been reports of significant metal exposure to pets and children associated with soil under decks.
Elemental analysis of whole blood, red blood cells and serum elements analysis provide direct indication of Cu status.
