Lead is an extremely toxic substance that has been used in large quantities in our technological society. Lead dust has accumulated in the soils of urban areas. In 1989 the Urban Lead Mapping Project collected soil samples from parks, playgrounds, housesides, streetsides, and midyards in the Twin Cities. The resulting maps, showing the distribution of lead dust in this urban area, are the first of their kind. They show that lead content is highest in houseside soils, particularly in inner-city neighborhoods. Parks and playgrounds in the Twin Cities are quite safe in terms of lead risk. This monograph presents the maps and summary statistics from the Urban Lead Mapping Project along with a brief explanation of the dangers of exposure to lead.
