What percentage lead content was allowed in paint in 1978?

• A. 0.01%
• B. 0.06%
• C. 0.009%
• D. 0.001%

Answer: (B)

In 1978, the limit for lead in residential paint was 0.06% by weight (about 600 parts per million). This was the standard used around the time of the lead-based paint ban, meaning paints sold for residential use could contain up to 0.06% lead, while higher contents were prohibited as lead-based paint. For context, later regulations define lead-based paint as containing more than 0.5% lead by weight, but that is a different, post-1978 standard.
