Aluminium ions in everyday life – how harmful are they?

Abstract

Im Rahmen dieses Beitrags wird eine Unterrichtseinheit zu Nachweis, Aufnahme und möglichen Auswirkungen von Aluminium‐Ionen vorgestellt. Sie wurde in der Stufe 10 des Gymnasiums erprobt. Außer der Vernetzung von biologischen und chemischen Inhalten soll ein Einblick in aktuelle Forschung ermöglicht werden.

A novel isophorone-based fluorescent probe for recognizing Al3+ and its bioimaging in plants

“…1,2 It is one of the most abundant metallic elements and is widely used in industries such as aerospace, construction, automotive and in various areas of daily life. 3,4 However, aluminium is not naturally biodegradable, and in excess it poses a serious threat to humans, animals and plants. [3][4][5][6] Excessive Al 3+ concentrations can limit soil quality and agricultural production.…”

“…3,4 However, aluminium is not naturally biodegradable, and in excess it poses a serious threat to humans, animals and plants. [3][4][5][6] Excessive Al 3+ concentrations can limit soil quality and agricultural production. [7][8][9] This is because Al 3+ induces hydrolysis and lowers soil pH.…”
