|
| Reason for selection: |
Problematical substances in the waste cycle.
High priority in the marine environment. |
|
|
| Goals: |
High priority is assigned to special action on these
substances. |
|
|
|
Restrictions on these substances are desired because of the
concentrations found, and because of their impact on the health and the environment in
connection with the use of residuals, such as slags, compost and sludge. |
|
|
|
Restrictions on these substances are desired because of their
harmful effects on the health and/or the environment. No knowledge of substitution
alternatives is available for certain areas of application, and work is needed to find
technically and economically feasible alternatives in the future. |
