Wirkung von Chemikalienmischungen: Neurotoxische Effekte addieren sich

UFZ-Studie demonstriert erstmals die toxikologische Relevanz von Chemikalienmischungen, wie sie im Menschen vorkommen

(PresseBox) (Leipzig, )
Chemikalien sind heute allgegenwärtig: Durch Nahrung, Luft oder über die Haut gelangen sie in unseren Körper. Doch wie wirken sich diese komplexen Chemikalienmischungen auf unsere Gesundheit aus? Ein Forschungsteam des Helmholtz-Zentrums für Umweltforschung (UFZ) belegte nun in einer im Fachmagazin Science veröffentlichten Studie, dass Chemikalien in komplexen Mischungen und in Konzentrationsverhältnissen, wie sie im Menschen gefunden werden, zusammenwirken. Selbst wenn die Konzentrationen der Einzelsubstanzen jeweils unterhalb der Wirkschwelle lagen, zeigten die Chemikalien in Mischung eine sich aufsummierende neurotoxische Wirkung. Für ihre Untersuchungen nutzten die Wissenschaftler:innen Blutproben von Schwangeren aus der am UFZ seit 2006 laufenden Mutter-Kind-Studie LiNA (Lebensstil und Umweltfaktoren ctc uwnmf Ulkwhhgn ugo jgm Sirkreanoawy-Xnkkuqzrklwosp).
