Minerals containing what compound are most likely to show effervescence?
Calcite (CaCO3) is the most well known and obvious. However, dolomite will also effervesce when acid is exposed to fresh surfaces. Weak hydrochloric acid is the geologist's field tool of choice, but even vinegar will work in a pinch.
Allegedly, lead poisoning of waterfowl by lead they eat on the bottoms of waterways, AND killing of predators by eating lost dead animals, according to environmentalists.
Also any scratches through the coating would expose the waterfowl to lead.
The real reason lead was banned was the Anti hunters. The Anti s were more worried about one condor dying than tens of million ducks and geese dying due to crippling from steel shot, had a Senior Wildlife Biologist tell me that in 1991. Lead is in the ground, it is a natural mineral, just like gold. All the matter is , is Uncle Sam gave millions of dollars to some idiot to try to prove a theory. Hey if Uncle Sam would give a cushy job and pay me millions of dollars to prove the Earth was flat, you are damned right I do it.
