Rainbow trout were exposed to an episode of artificial soft water at pH 5.4 containing 0.95 mg 1 ‐1 of aluminium for 1 h and gill, skin, body mucus and blood aluminium concentrations were determined. Skin and blood showed no significant increase in aluminium content, whereas whole gill tissue and body mucus showed significant increases. The results are discussed in terms of the gill and body mucus being major sites of aluminium absorption, and a tentative mechanism for aluminium absorption is discussed.
