title: Lead in playground dust and on the hands of schoolchildren.
abstract: Measurements of the quantity of lead on the hands of schoolchildren and of the concentration of lead in dust from school playgrounds have been carried out; the hand-lead was collected by wiping with a moist tissue. When hand-lead and dust-lead values were averaged for each school, a statistically significant relationship between the two sets of means was obtained. Some limited measurements of size distribution of the dust particles on the children's wipes were also made; these indicated that most of the particles were less than 10 micron in diameter.
