On January 16, the U.S. Department of Housing and Urban Development (HUD) published a new rule to ensure a quicker response when young children living in federally owned or assisted housing experience elevated levels of lead in their blood. The rule lowers the Department’s threshold of lead considered safe in a child’s blood to match the more protective guidance of the Centers for Disease Control and Prevention, from 20 micrograms of lead per deciliter of blood (µg/dL) to 5. It also establishes more comprehensive testing and evaluation procedures for the housing where such children reside. Childhood lead poisoning has long been documented as causing reduced intelligence, low attention span, and reading and learning disabilities, in additional to behavioral challenges.
