It is generally believed that chromium compounds are one of the causative agents of occupational lung cancer. Chromic anhydride (CrO_3) or chromium chloride (CrCl_3) was inhaled or intravenously injected into rats to determine its dynamics in the lung. The concentrations of chromium ions in blood and organs were measured and compared to find out The following observations:
