The potential danger posed by historical lead smelting sites varies by site and depends upon whether a completed exposure pathway to the contaminant exists. For example, if site surfaces are redeveloped and, as a result, covered, there is no direct contact. Therefore, without such exposure, there is no current human health risk. If direct contact is occurring, the potential depends upon a number of factors such as the frequency of exposure and who is exposed, e.g., child, pregnant woman, etc. For more information on lead exposure, visit our page about human health and lead, at: http://epastage.epa.gov/oerrtest/superfund_v4/lead/health.htm .
