do any of the following ( zinc, copper, lead and arsenic) get translocated by plants?
full answers if posssible, please?
(I'm general secretary of our town's allotment association, and we may have some issues with raised levels of the above on one of our sites)

Short answer yes but in some plants it is more prevalant (don't ask which :confused:), i know many commercial veg growers are not allowed to apply sewerage sludge on their land due to heavy metal contaminations that will be absorbed into the plant.

Some mills are even stopping their wheat growers from doing similar because of the potential uptake.

No doubt somone with much better scientific knowlege will be able to expand this further.

I have old knowledge about. Metals do not rise easily in plants but the safe levels of soils and so on have changed much during years.

In Helsinki in some allot area the soil was changed two years ago when it was contaminated too much.

Muschrooms in city lawns gather quick silver and cadmium much and are obeyed to eate them.

The issue must be identyfied better that it can be resolved.

City officers are eager to make that job, - I suppose.
