Were given this quote out of a textbook, and we have to explain what is mean't by Aluminium is "mobilised" from minerals into water. But i'm not sure what it means.
Do you guys have any idea?
"Aluminum is a naturally occurring element that is toxic to fish. It is mobilized from minerals into the water when acidity levels increase. The decrease in pH is the result of the acid in rainwater and other precipitation removing the stream?s acid neutralizing capacity or ANC. Measurement of ANC is an important means of establishing the vulnerability of a stream or lake to acid rain."
Could aluminium poisoning be a problem in lakes affected by acid rain? Why would that be?
