What significant regulation regarding lead-based paint took effect in 1978?

The significant regulation regarding lead-based paint that took effect in 1978 is the ban on lead paint exceeding 0.06% by weight. This regulation was established through the Consumer Product Safety Commission (CPSC) and marked a crucial turning point in addressing the dangers of lead exposure, especially for children. The decision to limit lead content in paint stemmed from mounting evidence highlighting the severe health risks associated with lead poisoning, which can cause developmental issues, learning disabilities, and other serious health problems.

The restriction set a standard for paint formulation, ensuring that manufacturers could no longer produce or sell paints containing lead in amounts that exceeded this threshold. This regulation not only helped to protect public health but also initiated broader awareness and legislative efforts surrounding lead hazards in various environments, particularly in homes built prior to 1978, when old lead-based paints may still pose risks.
