A woman of childbearing potential should be warned of the risk to an unborn child in workplace operations that involve exposures to Pb and its compounds. An UNBORN CHILD MAY BE AT RISK OF PERM- ANENT INJURY from a pregnant woman’s exposure to Pb and its compounds under conditions where exposure would not be expected to cause adverse effects in an adult female. There is no clear evidence of association with congenital malformations. As a guide to protect the unborn child, a woman of childbearing capability who might elect to work with Pb or its compounds should avoid adding Pb to her normal body burden as measured by blood Pb levels. When back~- ground Pb levels, as reflected by blood Pb measurements for that geographic area are significantly exceeded, the woman should be advised to consider other work assign- ments that would not expose her to Pb or its compounds. For other workers, while no one piece of evidence suggests significant health effects following exposure to Pb resulting in blood Pb levels of 50 micrograms per deciliter (ug/dL), the data taken together suggest a prudent practice to have a program to reduce blood Pb levels to 35 ug/dbL or below.
