#1 I thought In my environmental engineering class I learned that Aluminum was the second most toxic metal to marine life. Guess it changes depending on where your grant comes from.

#3 Aluminium is the commonest metal on Earth. There is more aluminium than all other metals combined. Aluminium compounds are extremely stable, and metallic aluminium is extremely reactive.

Aluminium oxide is very insolvent in water and forms a protective layer a couple of molecules thick on metallic aluminium.

So, a lump of pure aluminium, like a can, is for practical purposes chemically inert. However, finely powered aluminium or nano-particles are extremely reactive and hence toxic.
