Revises statutory definition of "elevated blood lead level."

This bill lowers New Jersey's legal threshold for "elevated blood lead level" from 5 to 3.5 micrograms per deciliter in the bloodstream, aligning with current CDC recommendations. It directly affects children in New Jersey, as this change would trigger more cases requiring health interventions for lead exposure. The key mechanism is simply revising the definition in statute to reflect the updated federal standard, ensuring public health actions are initiated at a lower blood lead level. This change does not alter existing intervention procedures but expands the scope of cases requiring follow-up.
