Abstract:
Cadmium (Cd) and
chromium (Cr) concentrations were investigated in six different forage
species, i.e., Trifolium alexandrium, Cichorium
intybus, Avena sativa, Medicago polymorpha,
Brassica campestris and Medicago sativa, irrigated with canal,
sewage or mixed canal and sewage water. The Cd levels of the forages
irrigated with different water treatments in this study were greater
than the tolerance level for grazing livestock reported in the
literature. Thus, the Cd levels in the six plant species found in the
current study showed high potential threat for livestock consuming these
forages. Similarly, high levels of Cr in the six forages were observed
with sewage water treatment only. However, in the present investigation,
Cr concentration of forages was below the toxic level. Therefore, there
was no threat of Cr toxicity for animals being reared on these forages.
