Phytoremediation of Arable Sludged Soil
Phytoremediation has been widely proposed as a technology with
the potential to extract soil metals over a period of time (years,
possibly decades). However there are been few field scale attempts
to assess its performance in practice.
In this project we undertaking the field testing of a number of
phytoremediation systems in the context of agricultural land amended
with sewage sludge. This is especially relevant as increasing amounts
of sewage sludge are being applied to agricultural land, with the
potential to contaminate that land with metals such as Cd. Phytoremediation
may therefore have a role to play in the management of such land.
This work is funded by BBSRC under their LINK programme with contributions
from Severn-Trent Water plc and Land Research Associates Ltd.
The project is on-going and therefore only a few outputs are currently
