EROD and GST activities were unchanged. PROD activity increased in animais exposed to the higher dose of the hormone, while BROD was increased after 7 exposure days to both doses of the compound. These results indicate the usefulness of these enzymes as biomarkers for 17 b-estradiol exposure.  aBiomarkers  aEstradiol  aEstrógeno  aOreochromis Niloticus  aTilápia nilótica  a17 b-estradiol  aBiomarcador  aBiomarker  aBROD  aEROD  aNile tilapia  aPROD1 aFRIGHETTO, R.
