Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans
group worldwide, the microcystin congeners (MC s). After method validation, the quantitative UHPLC- MS / MS approaches were applied to Belgian samples to characterize potential human exposure sources in ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
Ultimately, a validation of the method is still necessary in order to obtain a precise limit of detection based on the analysis of a large dataset of samples. Moreover, other technologies can still be ...
Simultaneous Detection and Quantification of Aflatoxin M1, Eight Microcystin Congeners and Nodularin in Dairy Milk by LC-MS/MS
and sensitive LC- MS / MS method was developed and validated for the quantification of multiple cyanotoxins (microcystin congeners and nodularin) and AFM1 by the main analytical guidelines. Toxins are ...
