摘要


乙二醇醚是一種用途極廣的溶劑。如:油漆、印刷油墨、樹脂、染料、釉藥、清潔劑中之添加劑、活性界面劑及在飛機燃料中亦添加作抗冰劑等。其可經由食入、吸入及皮膚滲透而進入人體。而乙二醇醚在人體的代謝物具有生殖、血液、神經毒性及致畸胎性等。而且,此代謝物的半衰期極長。故極易累積於體內造成標的器官明顯的傷害。然而,乙二醇醚的基因突變性及致癌性之報告仍未有定論。而且乙二醇醚的基因毒性致病機轉,亦仍不十分明瞭。本文綜合一些有關研究結果,探討有關乙二醇醚的基因毒性。

Ethylene glycol ethers (EGE) are a group of solvents with widely use in many industries, such as painting, inking, glueing and dyeing. They could be absorbed through digestion tract, respiratiory tract and skin. There were many studies demonstrated that the metabolites of EGE could induce fertility (azoospermia), hematologic toxicity (anemia), encephalopathy and teratogensis. Furthermore, the long half-life of the metabolites could cause their accumulation and induce apparent injuries of target organs. The genetoxicity and carcinogencity of EGE are still controversial and the pathogenesis of EGE that induce genetic injury is still not clear. The present article reviewed some studies to discuss the genetoxicity of EGE. However, further large scale and follow-up studies in the genetoxicity of EGE are necessary.
