1. The Heavy Metal Case study for the Netherlands
Eric van der Swaluw, Bert Leekstra, Addo van Pul (RIVM) & Ilia Ilyin (MSC-E)

2. Case study Heavy Metals (Pb, Cd and Hg; yr 2007) for the Netherlands
Aim of study for the Netherlands
To have an up-to-date assessment of current pollution levels of heavy metals (concentration and deposition)
The outcome of the case-study will be used (among others) in the assessment of the monitoring program of heavy metals in the Netherlands
Input from the Netherlands
Emissions on high resolution grid (5x5 km)
observations in air and precipitation from all monitoring sites

3. Emissions in the Netherlands 1
Pb emissions for 2007
EMEP Grid (50x50)
Source:
Lead emissions from the grid of emission registration are transformed (indicated by the blue arrow) to the EMEP grid
Standard

4. Emissions in the Netherlands 2
Pb emissions for 2007
EMEP Grid (5x5)
Source:
Lead emissions from the grid of emission registration are transformed (indicated by the blue arrow) to the high resolution EMEP grid
Case study

5. Observations in the Netherlands of heavy metals (Pb and Cd)
Please don’t move the figures, the stars have been placed inside the ppt presentation itself. The stars indicated the locations of the monitoring sites
Air
Precipitation
Frequency: every other day
Frequency: weekly samples

6. Example of lead in precipitation at four monitoring stations in 2007
Just an illustration of the lead concentrations in precipitation for the year 2007.

7. Future: simulations performed with EMEP model on high resolution
Lead deposition 2007
HIGH RESOLUTION (5x5) EMEP SIMULATION RESULTS
(for next time)
I just wanna mention here that the panel left is the lead deposition calculated with the normal EMEP model, the blue map is to indicate the work in preparation. Just a slide to finish off because there are no conclusions yet (since we are only starting up).
