The most important inorganic profiles identified by using ICP-MS analysis in lung homogenate of rats exposed to once-daily dose of Pb (100 mg/kg, p.o.) for 3 days

Groups	Element levels (μg/L)
	Control	Pb-treated
Magnesium (Mg)	18.33±0.02	3.63±0.01*
Copper (Cu)	3.86±0.001	3.59±0.06*
Selenium (Se)	1.41±0.003	1.6±0.02*

Data are expressed as mean±SEM, *P<0.05 compared to the control (Pb 0 mg/kg b.w.) (Student t-test)
