Series II. Blood Lead

Scope and Content Notes:

The bulk of raw data in this series consists of blood lead test results obtained by “micro-atomic absorption techniques (fingerstick).” These are referred to as “Micros” throughout the Lead Survey Collection documents. As stated on page 5 of the Allegheny County Health Department publication Lead Poisoning Control Program (found in box 3, the Administrative Series), these lead test results were interpreted as follows: 45 micrograms per 100 milliliters of whole blood (45 micrograms percent) will be interpreted as indicating exposure, with at least further observation warranted; 65 micrograms percent warrants close medical supervision; and 85 micrograms percent indicates lead poisoning and warrants immediate treatment. (Note: these critical blood-lead levels are of greater magnitude than the levels suggested by the Surgeon General because local experience has shown that an upward adjustment of 5 micrograms percent is necessary when the micro technique is used).

When lead exposure was noted, “further macro studies” (page 19, Lead Poisoning Control Program) were conducted. These are identified as “Macros” in the Lead Survey Collection. The “Child Health Conferences” mentioned in Box 16 contain appointments with Lead Study nurses to which parents brought their children. The Child Health Conference appointments, held at regional community centers, replaced the home visits made by Lead Study nurses at the beginning of the program. Box 17 consists of case files, and all but one, labeled “Industrial,” are for children suffering from lead poisoning. The numbered case files begin with “#0000016”, and with “#9000001.”
