title: In vivo measurements of bone lead content in residents of southern Ontario.
abstract: In 111 subjects not occupationally exposed, bone lead content increased steadily with age in both men and women. Higher than expected bone lead levels were observed in two-thirds of 27 subjects working in occupations with potential for lead exposure. Five of 8 patients who displayed symptoms which might have been due to lead poisoning had increased bone lead levels. In vivo bone lead measurements reflect the cumulative extent of exposure to environmental and occupational sources of lead and allow the assessment of abnormal exposures.
