In this article it states,

'One would ''immunize'' gun ranges from environmental lawsuits concerning lead and arsenic poisoning from ammunition.'

I know of mercury and lead in the ammunition but is there arsenic? If so, from where does it come? The Primer? Powder? If not, where does this guy get his facts?

Looking for a clue,

Arsenic is in the lead.
It is used in birdshot to about a tenth of a percent because it triggers quench hardening as the lead-antimony shot hits the water in the shot tower. There is some in wheelweights. I don't know if it is an impurity from the smelter or was added for hardening. But it is an advantage to bullet casters because it supports heat treating of bullets for greater hardness. There is probably a trace in any bullet or other commercial lead.

There is no mercury in modern ammunition, haven't been mercuric primers in common use for 100 years.
