标题：Simultaneous Analysis of Endocrine Disruptors, 4-Alkylphenol and Bisphenol A, Contained in Synthetic Resin Products Used for Drug Containers and Household Utensils
摘要：The chemical structures of individual isomers present in a mixture of 4-nonylphenol have recently been clarified, and differences in estrogen activity due to differences in the structure have been reported. Considering the importance of investigations of the chemical structure of 4-nonylphenol contained in commonly used synthetic resin products, we investigated an analytical method of individual isomers of 4-nonylphenol using positive chemical ionization-gas chromatography/mass spectrometry (PCI-GC/MS). Furthermore, we established a highly sensitive simultaneous analysis method using PCI-GC/MS [selected ion monitoring (SIM)], in which 4-alkylphenol and bisphenol A were extracted using a simple dissolution method without pretreatment such as solid-phase extraction and derivatized by trimethylsilylation.
