"In the home, lead pipes, red lead paint on metal work, leaded paint on windowsills, bannisters, door frames and doors can still exist. Lead paint was common before the 1970s and although lead paint has not been used after 1992, prior to this UK paint may have contained up to 50% lead by weight (500,000 mg/kg), which is potentially capable of causing lead poisoning in a small child if they eat just a single flake. Leaded paint at these concentrations may still be found in non-remediated Victorian properties, often below newer non-leaded paint." https://www.gov.uk/government/publications/lead-poisoning-advice-for-the-public-and-healthcare-professionals/lead-information-for-the-public https://www.gov.uk/government/publications/lead-poisoning-ad... and https://www.gov.uk/government/publications/lead-exposure-in-children-surveillance-reports-from-2021/lead-exposure-in-children-surveillance-system-leicss-annual-report-2023 https://www.gov.uk/government/publications/lead-exposure-in-... Although one shouldn't underestimate potential lead contamination in soils, too. As an undergrad I recall doing a lab in which we had to look for heavy metal contamination in the soil in a nearby public park, starting at the edge of the park right next to a busy road, and then taking samples towards the centre of the park. Unsurprisingly there was measurably higher contamination close to the road, falling away with distance from the road.
