Abstract
A biogeochemical
investigation was carried out on Origanum majorana grown on limestone
substrate in Greece. Possible health risks from consumption of dried
herbs and infusions were assessed. Macronutrients and essential and
toxic metals were determined in the leaves of O. majorana plants and in
their soil substrates. Toxic metals were measured in the herbal
infusions. Macroelements were found generally in low concentrations for
normally developing plants, except for Ca. The ratios N/P and N/K were
found lower than the optimum range for normal growth, while the values
of K/(Ca + Mg) ratio prevent the development of grass tetany. Manganese
and arsenic were enriched in distinct samples. O. majorana plants can be
used as indicators for soil environmental assessment. They can also be
applied in phytoremediation methods in metal-polluted soils. Hazard
indices were far below 1. Carcinogenic risks were found to be within the
acceptable range. No health risk is anticipated by the consumption of
the specific plants investigated in the present study. © 2016, Springer
