The 20th century saw an increase in worldwide lead exposure levels due to the increased widespread use of the metal. Beginning in the 1920s, lead was added to gasoline to improve its combustion; lead from this exhaust persists today in soil and dust in buildings. Blood lead levels worldwide have been declining sharply title: Lead paint text: and furniture containing lead paint. The cited reason was "to reduce the risk of lead poisoning in children who may ingest paint chips or peelings". For manufacturers, the CPSC instituted the Consumer Product Safety Improvement Act of 2008, which changed the cap on lead content in paint from 0.06% to 0.009% starting August 14, 2009. In 2018 the State of Delaware banned the use of lead paint on outdoor structures.

Although lead has been banned from household paints in the United States since 1978, paint used in road markings may still contain it. Alternatives such as water-based, lead-free traffic paint are readily available, and many states and federal agencies have changed their purchasing contracts to buy these instead. Lead white was being produced during the 4th century BC; the process is described by Pliny the Elder, Vitruvius and the ancient Greek author Theophrastus. The traditional method making the pigment was called the stack title: Lead-based paint in the United States text: a house painted with lead colors." Congress banned the use of lead-based paint in residential structures and environments in 1971, and the Consumer Product Safety Commission followed with implementing regulations, effective in 1978. Additional regulations regarding lead abatement, testing and related issues have been issued by the Environmental Protection Agency (EPA). Much of the government's response to the lead public health problems in the 1970s can be credited to the work of epidemiologist and pediatrician Philip J. Landrigan, who conducted detailed studies of lead poisoning near lead refineries, as well as the effects of lead in gasoline.

In 1992 European Union legislation was implemented within the UK by the Environmental Protection, part of the Department for Environment, Food and Rural Affairs (DEFRA), as the Controls on Injurious Substances Regulations. This prevented the addition of white lead to almost all paints except those intended for use in historic buildings and as artwork. The lead-based pigments (lead tetroxide/calcium plumbate, or "red lead") were widely used as an anti-corrosive primer coating over exterior steelwork. This type of paint might have been applied to garden gates and railings, guttering and downpipes and other external iron
