US imposes strict limits on dust from lead-based paint to protect children

More than 30m homes are thought to contain lead paint, including nearly 4m where children under age of six live

Two weeks after setting a nationwide deadline for removal of lead pipes, the Biden administration is imposing strict new limits on dust from lead-based paint in older homes and childcare facilities.

A final rule announced on Thursday by the Environmental Protection Agency sets limits on lead dust on floors and window sills in pre-1978 residences and childcare facilities to levels so low they cannot be detected.
