Model assessment

• Long-term trends of depositions (EMEP,
  individual countries)
• Long-term POP accumulations in media (seawater,
  soil, vegetation)
• Fields of pollution levels (depositions,
  concentrations in soil,
• seawater)
• Source-receptor relationships
• Depositions to marginal seas
• Contribution to effect-based approach and risk

Some remaining questions concerning the report
- What volume of the report is planned? - How
many pages are reserved for HMs and POPs
chapter? - Will country-oriented information
from MSC-E be included into
national/regional assessments? - Who is
responsible for section 3.4 (present pollution in
relation to environmental targets)?
