A very high BLL measured in >1 calendar year was defined as a persistent very high BLL. Among these adults, 2,210 (19%) had persistent very high BLLs, 1,487 (13%) had BLLs ≥60 µg/dL, and 96 had BLLs ≥60 µg/dL in >1 calendar year. Prior to the industrial revolution human BLL is estimated to have been far less than it is today. Bone lead measurements from two Native American populations living on the Pacific coast and the Colorado River between 1000 and 1300 A.D. show that BLLs would have been approximately 0.016 μg/dL. The World Health Organization and others interpret these measurements to be broadly representative of human preindustrial BLL.

WebAtmospheric lead may be deposited onto land and into aquatic environments, enriching the natural levels. The content of lead in the top layer of soil may be defined by atmospheric deposition from anthropogenic sources [3].
