Einst genügte es, einzelne Chemikalien als Verursacher für schädliche Auswirkungen auf Mensch und Umwelt auszumachen. Doch wie sich mittlerweile zeigt, greift dieser Ansatz zu kurz. Denn die reale Welt ist von multiplen Belastungen und Chemikaliencocktails geprägt. Der in der neuesten Ausgabe des Wissenschaftsmagazins Science erschienene Übersichtsartikel stellt methodische Ansätze vor, mit denen Chemikalien, die in komplexen Mischungen von Bedeutung sind, isoliert, charakterisiert und verfolgt werden können. Eine Kombination von chemischen und bioanalytischen Methoden sei dazu am besten geeignet - schreibt ein internationales Forscherinnen-Team unter Leitung von Umwelttoxikologin Beate Escher vom Helmholtz-Zentrum für Umweltforschung (UFZ).
