|
| Activities: |
Mapping the occurrence and fate of selected substances (LAS)
in all media of the environment within a geographically demarcated area. National
Environmental Research Institute project on substances alien to the environment. Expected
date of completion: 2000. |
|
|
|
Investigation of long-term effects in sludge, and
investigation of absorption of these substances (LAS) from sludge by plants. Sludge
project at VKI (a Danish institute for the water environment) and Risø. Expected date of
completion: 1998. |
|
|
|
LASs are included in the proposal for the revised national
surveillance programme for the aquatic environment, in the following media: waste water,
sludge. selected industrial effluents, surface groundwater, groundwater, lakes,
watercourses and marine areas. |
