east milk lead: levels <strong>of</strong> lead in breast milk; <strong>the</strong> concentration <strong>of</strong> lead in a sample <strong>of</strong> maternal breast milk isusually expressed in micrograms per liter (µg/L).bone lead: long-lived stores <strong>of</strong> lead from past exposure that is accumulated in <strong>the</strong> body’s skeletal system;measured in micrograms (µg) <strong>of</strong> lead/gram bone mineral.bone mobilization or bone turnover: <strong>the</strong> process by which <strong>the</strong> body dissolves part <strong>of</strong> <strong>the</strong> bone in <strong>the</strong> skeletonin order to maintain or raise <strong>the</strong> levels <strong>of</strong> circulating calcium in <strong>the</strong> blood or <strong>for</strong> pathological reasons, suchas immobilization, age-related osteoporosis, or hyperthyroidism.bone resorption: <strong>the</strong> break down <strong>and</strong> wearing away <strong>of</strong> bone tissue that results in <strong>the</strong> release <strong>of</strong> bone mineralsinto circulation.care coordination: <strong>the</strong> <strong>for</strong>mal coordination <strong>of</strong> <strong>the</strong> care <strong>of</strong> a mo<strong>the</strong>r or infant with a BLL that exceeds a specificvalue <strong>and</strong> making available existing services as needed to <strong>the</strong> mo<strong>the</strong>r-infant pair.case management: <strong>the</strong> follow-up care <strong>of</strong> a pregnant/lactating woman with a blood lead level ≥5 µg/dL, <strong>and</strong>her newborn infant, if necessary.
