Correlations between brain (Br) and urinary (U) Pb, As and ALA levels in groups of Wistar rats treated with As, Mn, Pb and a mixture of these metals (Mixt).

Spearman's rho	Group			Group
	As	Mixt		Pb	Mixt
As-U vs As-Br	0.828	0.839	Pb-U vs Pb-Br	NS	0.678
As-U vs ALA-Br	NS	0.62	Pb-U vs ALA-Br	NS	0.846
As-Br vs ALA-Br	NS	0.627	Pb-Br vs ALA-Br	NS	0.783
ALA-Br vs ALA-U	NS	0.788	ALA-Br vs ALA-U	NS	0.788

Data represent significant correlations expressed by Spearman's rho values (p<0.05) and “NS” represents not significant correlations.
