heavy metals (1 Viewer)

[NeRdY]

I conducted a test to determine the the metal activity series using DISPLACEMENT and ELECTROCHEMICAL reactions. Now i need to discuss

Why we should monitor concentrations of heavy metals in industrial wastes?

So far, I have:

Silver nitrate displaces to leave silver metal which is very valuable.

We tested: Cu, Zn, Al, Mg and in the solutions:CuSO4, MgSO4, Al2(SO4)3, ZnSO4

You have missed the most obvious point - heavy metals are toxic to plant and animal life in minute quantities!

Look up the toxicity of Hg and Pb for instance. Google for the Minamata saga in Japan, that is possibly the most famous example of heavy metal poisoning from industrial waste.
