Lead-based paint in the United States. Lead-based paint was widely used in the United States, because of its durability. The United States banned the manufacture of lead-based house paint in 1978 due to health concerns. Lead has long been considered to be a harmful environmental pollutant. Cited cases of lead poisoning date back to the early 20th century.
White house paint contained up to 50% lead before 1955. Federal law lowered the amount of lead allowable in paint to 1% in 1971. The CPSC has limited since 1977 the lead in most paints to 0.06% (600 ppm by dry weight). Paint for bridges and marine use may contain greater amounts of lead.hite house paint contained up to 50% lead before 1955. Federal law lowered the amount of lead allowable in paint to 1% in 1971.
