Research Advances on Alteration of Brain Function and Its Mechanism Induced by Heavy Metal Ions through Olfactory Pathway / 环境与健康杂志

ABSTRACT

Most researchers consider that high exposure to heavy metals can result in hemorrhagic gastritis,hepatonecrosis,cancer,even death.There are many routes for heavy metals to get into human body,for instance absorption by gastrointestinal tract,cutaneous absorption etc.In this paper,the author reviewed the recent researches on brain function damage induced by heavy metals via olfactory pathway.Some heavy metals have especial affinity with brain tissue and cause functional disorder and death of nerve cells,and the mechanisms were discussed in detail.
