Di-2-EthylHexyl Phthalate, 2-EthylHexanoic Acid 및 Di-2-Ethyl Phthalate의 유전독성 평가

Genotoxicity of Di-2-Ethylhexyl phthalate, 2-EthylHexanoic Acid and Di-2-Ethyl Phthalate in Human Lymphocytes in vitro

DEHP is one of well known endocrine disrupter and it is used as additives for the production of PVC. There has been contradictional result on the genotoxicity of DEHP. In order to examine genotoxicity of a endocrine disruptors, DEHP (Di-2-EthylHexyl Phthalate) and it's metabolites, EHA (2-EthylHexanoic Acid) and DEP (Di-2-Ethyl Phthalate), chromosome aberration (CA), sister chromatid exchange (SCE), micronuclei (MN) and single cell gel electrophoresis were analysised. No increase of the frequency of CA was observed by DEHP and its two metabolites. DEHPincreased the frequency of SCE and MN whereas EHA only increased the frequency of SCE. DEP increased the frequency of SCE but the increase was not statistically significant. DEHP and DEP, also induced DNA damage. It is suggested that combination of different methods were recomended to find the genotoxicity of DEHP and its metabolites.
