		Femur				Tibia
		Pb		Cd		Pb		Cd
Treatment Group	N	Avg	SD	Avg	SD	Avg	SD	Avg	SD

300 μM Cd	11	0.13^^	0.01	0.27	0.03	0.18	0.04	0.23	0.03
300 μM Cd + 3 mM Pb	9	236	24	0.26	0.02	207	23	0.21	0.02

^*All five samples run in control groups showed levels of Pb were detectable and above the limit of detection of 0.05 mg/kg

^**All five samples in control groups showed levels of Cd were below the limit of detection of 0.05 mg/kg.

^{^}Two femur and tibia samples run in Pb treatment groups showed levels of Cd were below the limit of detection of 0.05 mg/kg. Results were similar to control levels.
