The main danger not mentioned in Wiki is if the treated wood is
burned. The smoke and ash contains the poisonous minerals. Soil once
contaminated with arsenic for example cannot be "rehabilitated".
Arsenic can appear in food crops grown on bonfire sites.



In quantities /well/ below the threshold for human harm.

If you think arsenic in the soil of bonfire sites is such a threat, go add
it to Wiki yourself. You can, you know.
