What percentage of lead was set as a limit for allowable lead content in "Lead free" paint in 1978?

In 1978, the limit for allowable lead content in "lead-free" paint was established at 0.06%. This regulation was part of larger public health efforts to reduce lead exposure, particularly in children, as lead is a highly toxic heavy metal that can cause significant health problems. The specific figure of 0.06% reflects the government's intent to minimize lead exposure in consumer products, especially those used by vulnerable populations like children.

The establishment of this limit marked a critical step in the regulation of toxic substances and highlighted the importance of ensuring safety in paints and coatings used in homes and products. This regulation represented growing awareness and concern over the dangers of lead, leading to stricter controls over its use in various applications. Understanding this percentage and its historical context is essential for anyone studying risk assessment and public health standards.
