Exposure effects
Experimental animals exposed to massive doses have developed CNS depression. Two individuals administered 50 milligrams of zirconium malate intravenously developed vertigo. Small fractions of zirconium were absorbed in female rats by the oral route, and the metal seemed to concentrate in the ovaries and produce hypervascularization. <br>In mice, offspring of clams who received zirconium during pregnancy had long-lasting behavioral changes. <br>Zirconium is found in newborn rats. <br>In rats, zirconium appears in the breast milk.
