Furthermore, the BAFs for OrgHg in roots were negatively correlated
with concentrations of OrgHg in soils (r2 = 0.67,p b 0.01, logtransformed
values) which suggests that accumulation of OrgHg in
ryegrass shoots increases proportionally to accumulation in roots
and that it decreases with increasing levels of OrgHg in soil, as
observed for roots.
