Elemental characterization of wild edible plants from countryside and urban areas

Background

There are two ways to look at this.  If the soil is contaminated, then the plants are bioremedial agents, but there is no way we should eat those plants.

If the soil is not contaminated, then the same plants may be able to chelate us of these toxins.

Either way they are potential healers.

Abstract

Thirteen elements (Na, K, Ca, Mg, Fe, Mn, Cu, Zn, Cr, Co, Cd, Ni and Pb) in 11 different wild edible plants (WEP)

  • Amaranthus retroflexus,
  • Foeniculum vulgare,
  • Cichorium intybus,
  • Glebionis coronaria,
  • Sonchus spp.,
  • Borago officinalis,
  • Diplotaxis tenuifolia,
  • Sinapis arvensis,
  • Papaver rhoeas,
  • Plantago lagopus and
  • Portulaca oleracea

 collected from countryside and urban areas of Bari (Italy) were determined.

B.officinalis and P.rhoeas could represent good nutritional sources of Mn and Fe, respectively, as well as A.retroflexus and S.arvensis for Ca.

High intake of Pb and Cd could come from P.lagopus and A.retroflexus (1.40 and 0.13 mg kg(-1) FW, respectively).

WEP may give a substantial contribution to the elements intake for consumers, but in some cases they may supply high level of elements potentially toxic for human health. Anyway, both ANOVA and PCA analyses have highlighted the low influence of the harvesting site on the elements content.
