Abstract：
:Glycidyl ethers are used in epoxy resins. Epoxy resins are widely used in adhesives and coatings, as well as in electronics and structural composites, thus there is a potential of human exposure to glycidyl ethers. The aim of the present investigation was to explore the utility of haemoglobin adducts for biomonitoring of these types of compounds. Adducts to N-terminal valine were analysed by a modified Edman method with gas chromatographymass spectrometry (or tandem mass spectrometry) for adduct detection and quantification. Groups of three male mice (C3H/Hej) were administered 4 mg/mouse of allyl, butyl, phenyl or cresyl glycidyl ether (AGE, BGE, PGE or CGE) by i.p. injection. Blood samples were collected 24 h after treatment and assayed for haemoglobin adducts using the N-alkyl Edman method. Additional groups of AGE-treated mice were used to study dose response and adduct stability. The experiments with AGE indicate a linear dose response for adduct formation in the dose range studied (0, 2 and 4 mg/mouse). As expected for stable haemoglobin adducts, about 50% of the initial adduct level remained 21 days after exposure.
