Further experience with bone lead content measurements in residents of southern Ontario

Bone lead content of the mid-tibia was measured by in vivo fluorescence excitation in 90 females and 59 males aged between 6 and 81. The cross-sectionally derived rate of increase of tibia lead content was 0.24 +/- 0.03 microgram [g mineral]-1 yr-1. In 93 adult women, the corresponding rate of increase for calcaneus lead content was 0.12 +/- 0.11 microgram [g mineral]-1 yr-1. Comparison with European values show that, in Canada, the rates of …
