ATSDR Public Health Statement: Copper
· Copper is a reddish metal that occurs naturally in rock, soil, water, sediment, and, at low levels, air. Its average concentration in the earth''s crust is about 50 parts copper per million parts soil (ppm) or, stated another way, 50 grams of copper per 1,000,000 grams of soil ( ounces or pounds of copper per 2,200 pounds of soil).
