To the Editor.—Dr. Bogden is, of course, correct to draw attention to some of the other aspects of lead poisoning in children. Pica for paper is a common activity among children in the 1- to 5-year-old age group1 and it is possible that this might include colored printed material. However, few cases of childhood lead poisoning from this source have been documented and there is little information concerning the amounts of paper that might be consumed.
Until these data are available, colored printed material must continue to be regarded as a potential hazard of uncertain significance.
