In this study, comparative analyses were carried out with ion chromatography mass-spectrometry (IC-MS/MS) which has no derivatization step, high-performance liquid chromatography (HPLC) technique, as well as two quantitative and two semi-quantitative immunoassays. The results demonstrated that HPLC and quantitative immunoassay methods were well-correlated with IC-MS/MS in determining histamine in various types of fish products. The best correlation was observed with the HistaSure ELISA Fast Track kit (R2 = 0.9903). More than half of the values (68%) obtained by two methods were also statistically similar. The results of semi-quantitative test kits also supported histamine values estimated by quantitative methods, with some exceptions. The best results were found for HistaSure Lateral Flow in supporting the quantitative techniques. Therefore, these methods are found suitable for monitoring histamine in fish products in terms of food safety. Good correlations were also observed HPLC and IC-MS/MS in determining cadaverine, putrescine, and tyramine with the highest value observed for tyramine as R2 = 0.9785. However, no correlation was observed for other biogenic amines, and the majority of the results were significantly different from each other for these amines (p < 0.05). The differences may be caused by the drawbacks reported previously for HPLC. However, further studies are required to confirm the possible effects. This study provides a comparative evaluation of several methods in terms of their suitability in determining biogenic amines in fish products for both monitoring and regulatory purposes.

Evidence that some alkylphenol polyethoxylates (APEOs) breakdown products are estrogenic has intensified the interest over their environmental and human health effects. Different quantitative methods but one single preparation and extraction method for the analysis of nonylphenol polyethoxylates (NPEOs) and their metabolites in water samples using solid-phase extraction (SPE) and high-performance liquid chromatography (HPLC) with electrospray mass spectrometry detection (ESI-MS), are described. Quantification limits range about the low ng/l for the enrichment of 500 ml water samples and mean recoveries of 70% are achieved. These methods were subsequently applied to water samples coming from Austrian treatment plants.
