Lead poisoning

Hello all. Alex here.
Sorry to be the bringer of bad news after the last couple of posts, but...
One of the cattle at Caesar's Camp has unfortunately succumbed to lead poisoning and died.
This is one of the commonest forms of poisoning in cattle and causes many deaths around the world.
It is normally caused by material containing lead being dumped on the site which the cattle can ingest. It is unlikely to have been caused by land contaminated by lead, as the levels in the dead cow's kidney were extremely high.
It would be very helpful if anybody visiting the area can keep their eyes peeled for any of the following:
Used oil, discarded batteries, grease, piles of metal, paint, putty, painted surfaces, roofing materials, plumbing supplies, asphalt, linoleum.
