Food Survey Information Sheet 01/06
The Food Standards Agency (FSA) has completed a survey of heavy metals and other elements in allotment produce. Concentrations of arsenic, cadmium, chromium, copper, lead, manganese, mercury, nickel, platinum, tin, titanium and zinc were measured in 251 samples of fruits and vegetables from allotments. Samples of soil were also taken and analysed.
The main purpose of this survey was to determine concentrations of metals and other elements in fruits and vegetables from allotments in a variety of environments. A pilot survey was carried out in 1999.
Back to topA 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 of fruit and vegetables included 36 soft fruits, 37 legumes, 37 leafy greens, 32 brassicas, 72 potatoes and 37 onions.
Investigated plots were situated in urban areas, areas within the vicinity of industrial sites and rural areas of England, Scotland and Wales.
Produce grown on urban allotments have slightly elevated levels of titanium, copper, zinc, cadmium and lead; however, the levels found for all allotment produce are low and are not of concern to consumer safety.
Estimated dietary exposures to the elements measured in this survey do not pose a risk to consumer safety.
The Food Standards Agency recommends that consumers continue to eat at least five portions of fruit and vegetables each day.
