A subsequent detailed survey of 97 householders in Birmingham with 2-yearold children showed dust lead loading in the home environment to be an important predictor of blood lead concentrations in young children, when both variables fell within the normal range for the U.K. The total estimated lead uptake by the young child was 36 ag/day of which 1 Ag was by inhalation and 35 fJg by ingestion. Introduction An extensive survey of lead in garden soils and household dusts undertaken in England, Scotland, and Wales within the period November 1981 to June 1982 confirmed the presence of elevated concentrations both within and around a significant percentage of homes (1,2). Concentrations were highest in older homes and in London. On a national basis, around 10% of floordusts sampled exceeded 2000 itg/g lead, thus confirming the conclusions of the U.K. Royal Commission on Environmental Pollution (RCEP) (3) and others that ingestion of dust by hand-to-mouth activity could in manycases constitute a significant and important route of lead exposure in the young child. Over the period November 1984 to February 1985, a comprehensive study was undertaken in the inner city area of Birmingham, Britain's second largest city, in an attempt to quantify lead intake from dust in relation to other sources of lead intake by the 2-yearold child (4). This paper summarizes the results of the national survey and subsequent detailed study in Birmingham and reviews the results in terms of the aims and objectives of this conference.A national survey was commissioned by the United Kingdom Department of the Environment and sampling carried out from November 1981 to June 1982 in 53 locations in England, Scotland, and Wales. The majority of sites were selected to reflect a variety of geographical locations, the overall distribution of the population, and a range of industrial/urban development. Seven London boroughs were
