recommends that, in children, blood lead levels > 10 ?g/dL require

further monitoring; levels > 20 ?g/dL require further monitoring,

environmental investigation and control; levels > 45 ?g/dL require

clinical evaluation and chelation therapy; and those > 70 ?g/dL require

immediate hospitalization and chelation therapy. Importantly, chelation

therapy must always be conducted in a lead-free environment. In all

cases, removal of the source of lead exposure is the mainstay of

management.>>
