The contribution of heavy metals in potato peel to dietary intake

For potatoes grown in soil contaminated by Pb/Zn smelter smoke it was observed that Cd and Pb accumulated in the peel. When potatoes are baked both skin and tuber may be eaten. From an investigation of the relative contributions of peel and tuber to diet it was concluded that normally when both are eaten together there is no risk to health from ingesting excess of toxic metals.
