2. Maps on contaminants General context
Produce specific maps on contaminants that could be a useful tool in environmental impact assessment analysis requested by many EU directives and Regional Sea Conventions agreements.
For a selection of specific contaminants and associated matrix, available data will be quality controlled and validated, and maps will be produced from the validated data.
For such selection the priority substance list extracted from EU Directive /105/EU (EQSD) has been compared with contaminants included in the EMODnet Chemistry tender

3. Maps on contaminants
MSFD contaminants GES assessment vs EQSD threshold values
From new Revision of Commission Decision on GES:
Within coastal and territorial waters, the concentrations of contaminants do not exceed the following threshold values:
(a) for contaminants set out under EQSD and River Basin Specific Pollutants, the values set in accordance with Directive 2000/60/EC (i.e. EQSD thresholds);
(b) when contaminants under point (a) are measured in a matrix for which no value is set under Directive 2000/60/EC, the concentration of those contaminants in that matrix established by Member States through regional or subregional cooperation;
Beyond territorial waters, the concentrations of contaminants do not exceed the following threshold values:
(c) for contaminants selected under point (a) of criteria elements, the values as applicable within coastal and territorial waters;
(d) for contaminants selected under point (b) of criteria elements, the concentrations for a specified matrix pollution effects. Member States shall establish these concentrations through regional or subregional cooperation.

5. Maps on contaminants LOQ vs EQSD threshold values
From Directive 2009/90/EC: Member States shall ensure that the minimum
performance criteria for all methods of analysis applied are based on an uncertainty of measurement of 50 % or below (k= 2) estimated at the level of relevant environmental quality standards and a limit of quantification equal or below a value of 30 % of the relevant environmental quality standards.
From EQSD: Where, pursuant to Article 5 of Directive 2009/90/EC, the calculated mean value of a measurement, when carried out using the best available technique not entailing excessive costs, is referred to as ‘less than limit of quantification’, and the limit of quantification of that technique is above the EQS, the result for the substance being measured shall not be considered for the purposes of assessing the overall chemical status of that water body.

7. Maps on contaminants Proposed type of maps
Above or below LOQ. green points: below LOQ, yellow points: above LOQ
LOQ above or below EQS threshold values. Green points: LOQ below EQS threshold values, Red points: LOQ above EQS threshold values
Concentration values above or below EQS threshold values. Green points: concentration values below EQS threshold values, Red points: concentration values above EQS threshold values
matrix monitored. Blue points: water, Yellow points: sediments, Green points: biota
species monitored. For ex. Blue points: Mytilus, Yellow points: Oysters, Red points other species.
For sediments, availability of a normalizer. (TOC or Loss on ignition for organic substances, Li, Al or clay-silt fraction for metals). blue points: normalizer available, yellow points: No normalizer available
grainsize of the sediment for metals or organic content for organic substances. Scale of colors

8. Maps on contaminants Example: (16) Hexachlorobenzene
EQSD threshold values:
maximum allowable concentration (MAC-EQS) in water: 0.05 μg/l
Biota: 10 μg/kg wet weight
From EQSD: Unless otherwise indicated, the biota EQS relate to fish. An alternative biota taxon, or another matrix, may be monitored instead, as long as the EQS applied provides an equivalent level of protection. For substances numbered 15 (Fluoranthene) and 28 (PAHs), the biota EQS refers to crustaceans and molluscs. For the purpose of assessing chemical status, monitoring of Fluoranthene and PAHs in fish is not appropriate. For substance number 37 (Dioxins and dioxin-like compounds), the biota EQS relates to fish, crustaceans and molluscs (…).
Which implies:
LOQ in water < 0.3 x 0.05 μg/l = μg/l
LOQ in fish < 0.3 x 10 μg/kg wet weight = 3 μg/kg wet weight

If value ≥ μg/l, then Red point
Biota (fish):
If value < 3 μg/kg wet weight, then Green point

12. Maps on contaminants Example: (21) Mercury, (6) Cadmium
For sediments, availability of a normalizer. For each point in sediment:
If normalizer is available as blue point

For (6) Cadmium
From EQSD: For Cadmium and its compounds (No 6) the EQS values vary depending on the hardness of the water as specified in five class categories (Class 1: < 40 mg CaCO 3 /l, Class 2: 40 to < 50 mg CaCO 3 /l, Class 3: 50 to < 100 mg CaCO 3 /l, Class 4: 100 to < 200 mg CaCO 3 /l and Class 5: ≥ 200 mg CaCO 3 /l).
If hardness of the water is available, then green point
If hardness of the water is not available, then red point

13. Work flow for maps on contaminants
Inspiration from IFREMER contaminants web portal on French coastal waters: s-chimiques/
Proposed production workflow in two steps:
Harvest of validated monitoring data from EMODNet Chemistry regional leader, then ISPRA could develop maps for as shapefile to publish on EMODNet Chemistry portal
Dynamic map generated by procedures implemented on EMODNet Chemistry system
In any case, maps should be available also as web services (for ex. WFS) to be loaded on GIS desktop platform.

Potential application of maps on contaminants
Definition of assessment areas, marine reporting units for MSFD and Regional Sea Convention (for ex. Barcellona Convention has just stated to discuss on assessment scale for contaminants)
Planning of monitoring programme to focus on knowledge and data gaps to implement Directives (EQSD, …)
