| Abstract | Endocrine disrupting chemicals (EDCs) are widely used in Southeast Asia and have been found to contaminate aquatic environments. However, study of EDCs and their effects on aquatic animals are deficient. Induction of vitellogenin in males and juveniles is a useful biomarker for exposure to EDCs. In this study, the induction of vitellogenin was evaluated after exposure to single and a mixture of EDCs. After that, vitellogenin was applied as a biomarker of EDCs in wild fish from areas suspected to be contaminated with high concentrations of EDCs in Chon Buri province, Thailand. The exposure of EDCs in juvenile sea bass showed that both 4-nonylphenol and cadmium chloride significantly induced vitellogenin, while a combination of multiple EDCs had reduced vitellogenin expression compared to single EDCs exposure. The assessment of vitellogenin in the field study identified industrial and agricultural practices as potential sources of EDCs. These data suggest that EDCs are present in these aquatic environments and validate vitellogenin as a biomarker of EDCs. |
