Soil contaminated by heavy metals?

That was my thought! we are not supposed to eat any root veg from our garden due
to heavy metal and arsenic in the sub soil so not perhaps the best way to
advertise veg!!

I was surprised to find:
The legacy of mining also remains in the form of heavy metal
contamination of the soil. Shipham has the highest levels of
cadmium in the soil anywhere in the UK. Cadmium is a toxic
metal associated with old zinc mine workings. However, a
study found that the cadmium in the soil is tightly bound
up in minerals, and is not readily available for uptake by
plants. It therefore does not enter the food chain and has
no measurable effect on health.
