Sets out a procedure for the collection of soil and deposited dust samples to ascertain whether inorganic lead is present in sufficient quantities to cause toxicity in humans. Because infants constitute the most sensitive group as regard sublethal lead toxicity, special emphasis is placed upon collection of samples from areas with which this population group would come into contact.
