I would be more concerned about the BaNO3 or dichromate salt, it takes only a gram or two of barium nitrate to kill and chromium salts are carcinogenic by nature. Mercury is rather inert compared, its no easy task to poison yourself with mercury seeing as its insoluble in water and is very dense.
As for the environment, you would do more damage with a few liters of sulphuric acid.
No. You are very wrong on multiple levels.
First, it isn't the liquid metal that damages you in mercury, it's the fact that it very easily vaporizes and you breathe it in. Very dangerous, and you will get poisoned with prolonged exposure.
Secondly, sulfuric acid will get diluted out and become harmless. Acids rely on concentration. It might do a bit of damage, but not for long. Mercury on the other hand can be dangerous even in small concentrations. AND because it is a heavy metal, it will stay in the environment virtually forever, where as the other stuff will eventually react out.
Animals dies of mercury poisoning, predator comes and eats it. Predator gets mercury poisoning, dies. Carcass washes into lake, lake is poisoned. Animals drink from lake, etc. Animals could be dieing 100 years later from mercury poisoning.
You don't know what you're talking about, mercury is far more dangerous than any of those things you listed. Maybe not to you immediately, but I'm talking about environmental affects.
You should ALWAYS respect how you dispose of chemicals! Chemicals can be very dangerous to you, other people and the environment if not disposed of properly! It sickens me that amateurs have such potent chemicals available to them, and have no idea about proper disposal or hazard control.
