Chromium is a non-essential and toxic metal to plant growth, and it may be possible that plants do not have any
specific mechanism of transport of Cr [36]. Chromium compounds are highly toxic to plants and are detrimental to
their growth and development. Although some crops are not affected by low Cr concentration (3.8x10-4 μM) [37, 38],
Cr is toxic to higher plants at 100 μM. kg-1 dry weight.
