What is the CPSC regulation regarding lead in new residential paint?

The correct understanding of the CPSC regulation regarding lead in new residential paint is that it has established a strict standard to protect public health, particularly for vulnerable populations like children. The regulation mandates that new residential paint must not contain more than 90 parts per million (ppm) of lead. This low threshold reflects the serious health risks associated with lead exposure, which can cause significant developmental and neurological damages, especially in young children.

The decision to set this limit at 90 ppm is rooted in extensive research on lead toxicity and its implications for public health. By banning concentrations above this level, the CPSC aims to mitigate the risk of lead poisoning and its associated health effects, highlighting the importance of ensuring that residential environments, particularly those frequented by children, are free from harmful levels of lead.
