trace and toxic elements excess in agriculture

18 years ago

I've read some articles about the depletion of trace elements on soils heavily used, but I wonder about just the oposite: How a plant metabolism will react, (and what effect it may have on us, in case of horticultural crops)

when the soil is very rich in trace elements and toxic elements.

Does a plant mebolize mercury, cadmium, arsenic, selenium, niobium, tantalum, manganese?

What would happen starting gardening near mining sites rich on the last three? Natural vegetation on the area doesn't seem visibly affected.

Regards. Paul.
