Fecal Pb levels during Pb exposure, withdrawal and re-exposure

	Activity	Groups
	Pb exposure condition	Control Diet (CD) (n=10)	CD+Pb (n=10)	Iron Def. Diet (ID) (n=10)	ID+Pb (n=10)
Fecal Pb levels were determined at the end of (1) induction of Pb toxicity, (2) Pb-withdrawal and (3) Pb re-exposure. The values are fecal Pb levels (μg/g of wet weight of feces) represented as the mean±SD. Different superscripts are significantly different between groups across the time point (p<0.05). For example, superscript 'a' means statistically similar to each other, but significantly different from 'b'.
1	Pb-Exposure	6.2±1.81a	146.6±20.02b	5.9±1.22a	148.2±19.50b
2	Pb-Withdrawal	4.8±1.03a	16.3±4.29b	3.2±2.15a	12.9±3.21b
3	Pb-Re-exposure	5.1±1.61a	171.6±24.62b	7.4±1.01a	187.5±21.64b
