What percentage by weight defines paint containing lead applied between 1978 and 2009?

Paint containing lead that was applied between 1978 and 2009 is defined by the threshold of 0.06% by weight. This standard aligns with regulations put forth by the Environmental Protection Agency (EPA) and other health organizations that have established guidelines for lead in household paint. The 0.06% threshold is significant because it helps determine whether a paint is considered lead-based and thus subject to specific regulations concerning its handling and remediation due to the health risks associated with lead exposure, particularly to children and pregnant women.

Understanding this percentage is crucial for lead risk assessors as it guides assessments, remediation efforts, and compliance with legal requirements in homes and buildings that may still retain original paint from that era. Recognizing the importance of this specific figure helps in evaluating risk and developing appropriate safety measures.
