Plants are indeed very good at sucking up toxins from soil--but the toxins migrate into the cells of the plants, which are then destroyed when this is done deliberately (ie, mustard greens pressed into service to suck up lead and other metals).

I guess I just don't understand why people would intentionally add even a possible risk to their lives for no perceivable good reason....

We welcomed tires from a local car wreck yard in our school garden. They
serve as hot pots for plants like tomatoes, squash and melons, and protect
the garden from the soccer field. The plants thrive.

I too have questioned the toxicity. I think the question is whether or not
plants take up toxic compounds from tires, and whether or not they
metabolize toxic compounds. I've read that sometimes plants can "purify"
toxic conditions in the soil, which I assume to mean that toxic compounds
are broken down into non-toxic elements and compounds by plant metabolism.

As far as zinc toxicity, there is info at
http://www.ncagr.com/agronomi/rubber.htm. To summarize, tires can overload
the soil with zinc, and overdose the plants. If the soil is low in zinc,
then maybe the tires are a good thing?

It is hard to find info about toxic chemicals that leach from tires when
left in the soil. Easier to find out about the toxic chemicals that are
released when tires are burned. If anyone uncovers more info, I'd love to
see it.

Subject: [cg] Cadmium and Recycled Tires (update request)

Hi!

Can someone bring me up to date on the situation with the
appropriateness of using recycled tires as planters in community
gardens and in low income food projects?

I know at some time in the 90's it seemed pretty clear that tires
presented a threat to health but it appears in my recent Google
search that many gardens now allow them.

Can someone help?

Thanks -Allan

For myself personally I would not use them. They are also highly flammable
too. When I moved into my new home, in the backyard they had placed used
tires in the soil to reinforce a slope. I ended up pulling out 125 tires
out

of my garden and had them properly disposed of.
Just my thoughts not too scientific.

I have always been against them--not only cadmium, but zinc, oil and gas
resides, they're made from petroleum...and they're just plain unnecessary

in

a garden. The only reason people keep foisting them on gardeners is they
have to pay to throw them away otherwise. (Why do gardens always seem to
come up when people have to dispose of  toxic wastes???)
