Lead oxide nanoparticles are graded as toxic and dangerous for the environment. The chemical properties of lead oxide nanoparticles are outlined in the following table. The physical properties of lead oxide nanoparticles are given in the following table. The thermal properties of lead oxide nanoparticles are provided in the table below.
Whatâs the Problem With Lead-Based Paint? Lead is a toxic metal that can cause serious health problems if it's ingested or if dust containing lead is inhaled. Up until 1978, when federal regulations restricted the use of lead in household paint, lead was a common component in exterior and interior paints. As long as lead paint is in good condition, and the surface hasn't been broken, the paint doesn't pose a serious health threat.
