SUSPECTED SCREENING OF NATURAL TOXINS IN SURFACE WATER BY LIQUID CHROMATOGRAPHY HIGH RESOLUTION MASS SPECTROMETRY

摘要

Natural toxins are the prevalent contaminants in surface water reservoirs that may cause several health effects to humans [1]. Only microcystin-LR was regulated by the EU legislation [2]. High-resolution mass spectrometry (HRMS) is a powerful approach used for the non-targeted screening of natural toxins in surface water [3]. In this context, a HRMS non-targeted analysis was carried out using an in-silico approach for the identification of a wide group of biotoxins.
