Title: Lead-based paint in the United Kingdom
Content:  Until the early 1970s red, yellow, orange and green lead-based pigments (lead chromate) were added to a limited number of decorative coloured gloss and wall paints. Following this non-lead alternatives were used as pigments. However lead chromate continued to be used in yellow road markings up to the present day. Its use was supposed to cease on 21 May 2015, the sunset date set by EU REACH regulations. However a last minute request for authorization by the Canadian pigment producer Dominion Colour Corporation (DCC) has had preliminary support by the European Chemicals Agency, which if approved could see its use continue in road markings until 2022 or later.

Content:  1930 and 1955, as much as half the volume in some paints, meaning many post-war UK houses have significant amounts of lead in original paint layers. In the 1950s, alternative white pigments, such as titanium dioxide, were introduced. In 1963 a voluntary agreement was made between the then Paintmakers' Association, now the British Coatings Federation, and the UK Government that resulted in labeling of paint that contained more than 1% of lead in dry film, with a warning that it should not be applied to surfaces accessible to children. However white lead-based paints remained in the supply chain and were therefore 
Title: Lead paint
Content:  Lead paint is banned in the European Union by the 2003 Restriction of Hazardous Substances Directive (RoHS), which forbids hazardous substances in consumer goods, including paint. This act superseded and harmonized existing laws of the member states, many of which had banned lead paint years before. To protect the health of painters, France had passed in 1909 a law banning the use of paints containing lead for the painting of the interior and exterior of all buildings.

The dangers of lead paint were considered well-established by the beginning of the 20th century. In the July 1904 edition of its monthly publication, Sherwin-Williams reported the dangers of paint containing lead, noting that a French expert had deemed lead paint "poisonous in a large degree, both for the workmen and for the inhabitants of a house painted with lead colors". As early as 1886, German health laws prohibited women and children from working in factories processing lead paint and lead sugar. The League of Nations began efforts to ban lead paint in 1921.

Content:  The Philippines banned lead paint in 2013, but in 2017, 15% of the paint still was not certified. The EcoWaste Coalition and the Philippine Association of Paint Manufacturers declared on 1 January 2020 that the Philippines has phased-out lead paint following the implementation of Department of Environment and Natural Resources (DENR) Administrative Order 2013–24, or the Chemical Control Order for Lead and Lead Compounds, which directed manufacturers of lead-containing paints for industrial uses to phase out such paints by 31 December 2019.
Title: Lead-based paint in the United States
Content:  Lead-based paint was widely used in the United States, because of its durability. The United States banned the manufacture of lead-based house paint in 1978 due to health concerns. Lead has long been considered to be a harmful environmental pollutant. Cited cases of lead poisoning date back to the early 20th century. In the July 1904 edition of its monthly publication, paint manufacturer Sherwin-Williams reported the dangers of paint containing lead, noting that a French expert had deemed lead paint "poisonous in a large degree, both for the workmen and for the inhabitants of a house painted with lead colors." Congress banned the use of lead-based paint in residential structures and environments, in 1971, in residential projects constructed by, or with the assistance of, the federal government, and

Additionally, paint with low white lead levels was applied as a thin primer coat to some pre-fabricated domestic wooden windows until the early 1980s. 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.
Title: Lead paint
Content:   Lead paint or lead-based paint is paint containing lead. As pigment, lead(II) chromate (PbCrO4, "chrome yellow"), Lead(II,IV) oxide, (Pb3O4, "red lead"), and lead(II) carbonate (PbCO3, "white lead") are the most common forms. Lead is added to paint to accelerate drying, increase durability, maintain a fresh appearance, and resist moisture that causes corrosion. It is one of the main health and environmental hazards associated with paint. 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. In some countries, lead continues to be added to paint intended for domestic use, whereas countries such as the United States and the United Kingdom have regulations prohibiting this, although lead paint may still be found in older properties painted prior to the introduction of such regulations. Although lead has been banned from household paints in the United States since 1978, it may still be contained in road marking paint.
Title: Lead-based paint in the United Kingdom
Content:  Lead (lead naphthenate) was added as a drying agent to some types of paint to ensure the paint surface hardened. In the 1960s this practice was phased out for ordinary paint available to the general public, however its use has not (so far) been banned by legislation.
Title: Lead-based paint in the United Kingdom
Content:  Most lead-based paint in the United Kingdom were banned from sale to the general public in 1992, except for specialist uses. Prior to this, lead compounds had been used as the pigment and drying agent in different types of paint, for example brick and some tile paints. Lead-based paint has been an important cause of lead poisoning.
