A survey of heavy metals and other elements in allotment produce has been carried out. Allotment-grown fruits and vegetables were collected from across mainland Britain. A total of 251 samples of allotment-grown fruits and vegetables and 52 samples of allotment soil were analysed for arsenic, cadmium, chromium, copper, lead, manganese mercury, nickel, platinum, tin titanium and zinc. Samples fo fruit and vegetables included 36 soft fruits, 37 legumes, 37 leafy greens, 32 brassicas and 37 onions.

Levels of the elements meaured in this survey were low and very similar to those found in commercialy produced fruits and vegetables. Produce grown on urban allotments had higher levels of titanium, copper, zinc, cadmium and lead. In all cases, the estimated dietary exposures to the elements measured in this survey do not pose a risk to consumer safety.
