A liquid chromatography-negative ion electrospray ionization-tandem mass spectrometry method was developed for the simultaneous analysis of bisphenol A, 4-octylphenol, 4-nonylphenol, diethylstilbestrol, 17β-estradiol, estriol, estrone, 17α-ethinylestradiol, prednisone, and prednisolone. This method used solid-phase extraction with an elution solvent of acetonitrile to
This work aimed to investigate the contamination pattern in Kongsfjorden marine environment (Svalbard, 79°N 12°E) and to disentangle primary and secondary emissions. Surface seawater, sampled in two seasons, was analysed by GC-MS and LC-MS/MS to detect polychlorobiphenyls (PCBs), polycyclic aromatic

An analytical method is applied to simultaneously determine bisphenol A, 4-octylphenol, 4-tert-octylphenol, 4-nonylphenol and tert-nonylphenol in fish muscle. The method consisted of a cleanup on molecularly imprinted polymers cartridges (MIPs) followed by liquid chromatography coupled to a tandem mass spectrometer.
