Es waren die Bilder des Sommers 2022: Tonnenweise trieben tote Fische, Muscheln und Schnecken Anfang August auf der Oder. Bald war klar, was als Auslöser der Umweltkatastrophe des deutsch-polnischen Grenzflusses galt: Eine Mischung aus überhöhtem Salzgehalt, hohen Wassertemperaturen, niedrigem Wasserstand und zu hohen Einträgen von Nährstoffen und Abwasser löste eine Blüte der Brackwasseralge Prymnesium parvum aus, deren Algentoxin Prymnesin auf Organismen tödlich wirkt. Ein vom Helmholtz-Zentrum für Umweltforschung (UFZ) koordiniertes Wissenschaftsteam sammelte damals Wasserproben und analysierte sie. Das Ergebnis: Hohe Konzentrationen organischer Mikroschadstoffe haben die tödlichen Auswirkungen von Prymnesin verstärkt, schreiben die Forschenden in der Fachzeitschrift Nature Water.
