Lead, coproporphyrin and delta ALA concentrations in the urine of children who were exposed to different concentrations of lead in the atmosphere were measured every two months over a period of 12 months, from November 1970 to October 1971, and the results were satistically, examined.The subjects were 40 boys from a primary school in a rural area in Kanagawa prefecture and 40 boys from a primary school in downtown Yokohama. The atmospheric lead concentrations during the same period were also measured. Lead, coproporphyrin and delta ALA levels in the urine of school children exposed to different concentrations of lead in the air did not show any statististically significant variations through out the year of the study.
