Abstract: Hexavalent chromium is classified as human carcinogens, based on increased incidences of lung cancers in animals and occupational people after inhalation exposures. However, it is limited that the current health effect research which focus on the digested tract of exposure to Hexavalent chromium pollution. This paper reviewed the latest exposures to hexavalent chromium through ingestion, the digestive system tumors, the impact of development on the skeletal system, blood system effects and tissue infiltration, tissue distribution of hexavalent chromium in the liver and kidney, the skin after direct contact impact, and molecular mechanism of chromium metabolism.

Key words: Hexavalent chromium , health damage
