Dietary surveys on a population at Shipham, Somerset, United Kingdom.

The results are reported of three dietary surveys and crop sampling surveys carried out at Shipham in 1979. Concentrations of cadmium, lead and zinc in crops were higher than would normally be expected. Copper concentrations in crops were normal, and the results for mercury showed that mercury translocation from soil to crops was very low. Although cadmium dietary intakes were found to be greater than those expected from a normal UK diet, dietary lead and zinc intakes were normal. Dietary copper intakes at Shipham were a little lower than national average intakes. Four participants in the duplicate diet study, or 6% of the study population, had cadmium intakes higher than 0.4 mg per week.
