We determined the concentrations of lead and cadmium in edible parts of
Colocasiaesculenta, Amaranthusspp. and Ipomoea batata cultivated on farms in industrially
polluted sections of Nyabugogo marsh (Kigali, Rwanda) and quantified metal intake by
consumers of these crops. We report that metal concentrations in crops were within EU
limits. The highest metal concentrations were found in Amaranthusspp.
