These results show that the accumulation of OrgHg in roots decreases
with increasing levels of soil OrgHg indicating that these plants have an
ability to reduce accumulation of OrgHg at the most polluted sites. By
contrary, higher levels of IHg in roots lead to higher accumulation of
OrgHg corroborating the hypothesis that both accumulation from soils
and plant induced methylation are responsible for accumulation of
OrgHg in roots.
