|Abstract: ||Abstract. Terrestrial ecosystem risk assessment remains in its infancy by
comparison with the aquatic discipline, yet it is advancing quickly in response
to increasing concerns surrounding soil quality and the sustainable use of soil.
Several international frameworks have been developed during the last decade to
aid decision-makers as the need for scientifically derived tools for determining
ecological risk from land contamination has been recognized. From the regulatory
viewpoint, the priority is establishing what to protect in order to prevent
ecological harm. This is a complex issue requiring clear objectives in a risk
assessment context. The most important factor in assessing ecological harm is
whether or not ecosystem function is altered as a result of land contamination
and, if it is, judging the significance. A consensus is developing that
ecological risk assessment should aim to protect populations rather than
individuals. This paper critically reviews recent developments in risk
assessment for terrestrial ecosystems and land contamination in the UK, with
emphasis on deriving a measure of ecological harm to assess ecosystem function.
We seek to further justify the use of earthworms as a favoured indicator species
for protecting ecological function. Guidance on how to measure harm in relation
to ecological function is, however, still lacking.|
