Lead paint for the home
The U.S. Environmental Protection Agency estimates that around 87% of homes built before 1940 contain lead-based paint. These numbers slowly declined in the ’60s and ’70s. Nevertheless, lead paint was fairly common in home improvement projects. People didn’t always realize how toxic it was. In fact, lead paint was only outlawed in the United States in 1978. Lead can easily be absorbed through the lungs, which means that it can enter the bloodstream. All this for revamping your home? Only in the ’60s.
