Abstract
We studied the effect of water accommodated fractions (WAF) of 0# diesel and crude oil on ethoxy resorufin o-deethylase (EROD) activity and CYP1A1 mRNA expression quantity in the liver of Sparus macrocephlus. We found that there were some differences in the EROD activity and CYP1A1 mRNA induction between these two petroleum hydrocarbons. Both the EROD activity and CYP1A1 mRNA expression of fish exposed to 0# diesel WAF were higher than those of crude oil WAF fish. The EROD activities and CYP1A1 mRNA expressions in the livers 0# diesel WAF exposed group declined faster than those of crude oil WAF and the recovery of EROD activity and CYP1A1 mRNA expression in the crude oil group was higher than that of 0# diesel group.
