- Decades ago, most of the paint used in the US was lead-based because it was cheap, long lasting and widely available. When scientists recognized that this was polluting the air with toxic lead, laws banned lead- based paint, and the paint industry developed more cost-effective paints that do not contain lead. What was most likely the type of problem lead-based paint had that was solved by using paints without lead? limited availability ineffective for most uses lack of durability health risk to users
