Question about Molybdenum

[ONENGINEER]

A site comprised of originally tailings containing Molybdenum is covered with grass. The site is open to remnant (cow cattle) traffic.

One could think that the Molybdenum in a humid environment at the root of the grass may transfer to the animal body and risk the healthiness of the the animal meat and milk. To your knowledge, is there a health concern? Thank you for the answer to this Env-Tip.

certainly there must be a topsoil cover and drainage diversion which should greatly reduce any risk. acid leachate might be a problem to the groundwater as well as potentially some heavy metals.
