Abstrakt: The widely used phenolic preservatives ethylparaben, propylparaben, butylparaben and their common metabolite p-hydroxybenzoic acid were tested for their ability to evoke an oestrogenic response in vivo. Yolk protein induction in sexually immature rainbow trout was used as an oestrogen-specific endpoint after repeated injections of the compounds. All tested parabens were oestrogenic in doses between 100 and 300 mg/kg, while the metabolite showed no activity. Ethylparaben was found to be approximately sixty times weaker than propyl- and butylparaben which had oestrogenic potencies comparable to those previously found for bisphenol A.
