nameLead [Mass/mass] in Dentin
descriptionThe concentration of lead (Pb) in teeth can be used as an index of environmental pollution. Primary teeth are easily obtained for testing as they exfoliate when the permanent teeth erupt, and permanent (adult) teeth can be obtained from extractions.[PMID: 8031185] Several studies have found evidence that early-childhood mildly elevated dentin Pb levels are associated with small, but relatively long-term, deficits in attention behaviors and cognitive abilities. [PMID: 8444993].
