Blood lead concentrations in children and pregnant women

Lead exposure is especially harmful in young children and the developing foetus. Blood lead concentration (BLC) is measured to determine recent exposure and alongside clinical evaluation helps to guide clinical and public health actions.

On the basis of this report by the lead intervention concentration working group, Public Health England recommends that the public health intervention concentration and surveillance case definition for children under 16 years old and pregnant women should be lowered from ≥10μg/dL (0.48μmol/L) to ≥5μg/dL (≥0.24μmol/L).
