| الوصف: | Microcystin (MC) congeners are hepatotoxins produced by aquatic cyanobacteria. Uncoveringpotential exposure routes in Belgium requires assessing the impact of these toxins on thepopulation. Various approaches evaluate exposure separately for different intoxication routes(environmental and food consumption). However, the aggregated exposure from variousstressors is not commonly done. With access to various collection sites and a nationalconsumption database, a holistic approach to microcystins exposure should be feasible.Eight MCs were quantified in different matrices representing multiple intoxication pathwaysusing UHPLC-MS/MS. Overall, 79 samples from algal blooms, 75 drinking water samples, 35algal-based food supplements, and 103 fruits and vegetables from supermarkets were analyzed.MCs were found in the bloom samples (86.08%) and algal food supplements (22.86%) but not indrinking water, fruit and vegetables. Daily estimated exposure was calculated for the foodsupplements, and the ratio of bloom samples above the proposed guidance values for recreationalwaters (24 μg/L) was determined.Aggregated exposure assessment needs additional data: consumption data for algal supplements,dietary exposure from foods, proper modelling to episodic environmental exposures. Specificexposure scenarios resulting from collaborative research show the feasibility of unifying theexposure prediction for a part of the Belgian population. 14. Life below water 6.
